Description

How to Evaluate Shoes

The present invention relates to a shoe evaluation method, and more particularly, to a shoe evaluation method which provides shock to the lower or upper surface of a shoe sole and measures the amount of shock penetrating the opposite surface of the shock application to calculate a shock absorption amount, generates shock absorption grade information of a shoe based on the calculated shock absorption amount, thereby presenting a standardized criterion for the shock absorption performance of a shoe, and further generates and provides information on the decline time required for the shock absorption grade to decline as the durability of the shoe is consumed, thereby providing a criterion for a user to determine when to replace the shoes he or she is wearing.

The structure of shoes is developed in various ways depending on the purpose of use. If we look at the structure of a typical shoe, the shoe is composed of the upper part, which wraps the entire upper part of the foot and maintains the external design and shape of the shoe, and the sole part. The sole is then layered in the order of the outer sole, midsole, innersole, and insole from the bottom.

Shoes are used for various purposes such as warmth, slip prevention, and fashion, and are mainly used to protect the user's feet from various hazards during physical activities such as walking and running, or to absorb and alleviate the shock generated by the user's body weight when the feet touch the ground.

In particular, shock absorption of shoes is a very important function for users with diseases of the plantar, joints, and spine, and therefore users with diseases of the plantar, joints, and spine should select and purchase shoes with high shock absorption when purchasing shoes.

However, since there has been no standardized standard for evaluating the shock absorption performance of shoes in the past, it is difficult to objectively compare shock absorption performance. Accordingly, since users have been purchasing shoes based on the feeling of wearing them temporarily for a short period of time before purchasing, there is a problem that they may fail to purchase shoes with appropriate shock absorption performance.

In addition, as shoes become less durable and less shock-absorbing with use, users must rely on their own senses to judge this reduction in shock-absorbing performance. This can lead to problems such as missing the timing of shoe replacement, which can cause strain on the soles, joints, and spine.

Republic of Korea Patent No. 10-1935050

The present invention is intended to solve the problems of the prior art mentioned above, and an object of the present invention is to provide a shoe evaluation method capable of presenting a standardized criterion for the shock absorption performance of a shoe by providing shock to the lower or upper surface of the shoe sole according to set evaluation conditions, measuring the amount of shock penetrating the opposite surface of the shock application, calculating the amount of shock absorption, and generating shock absorption grade information of the shoe based on the calculated amount of shock absorption.

In addition, another purpose of the present invention is to provide a shoe evaluation method that can provide a criterion for a user to determine when to replace a shoe by generating and providing information on the decline time required for the shock absorption grade to decline as the durability of the shoe is consumed.

In addition, another object of the present invention is to provide a shoe evaluation method in which a user terminal determines a decrease in shock absorption level according to a user's wearing time based on information on the wearer's wearing time of the shoe, and outputs an alarm to the user regarding the decrease in shock absorption level.

A shoe evaluation method according to one embodiment of the present invention includes a step of performing a shoe evaluation on shock absorption of a shoe sole, wherein the step of performing the shoe evaluation may include a step of setting evaluation conditions, a step of applying a provided impact amount according to the set evaluation conditions to a lower surface or an upper surface of the shoe sole and measuring a penetration impact amount on a surface opposite to the impact providing surface, a step of generating shock absorption grade information of the shoe based on the provided impact amount and the measured penetration impact amount, and a step of generating shoe evaluation information including the shock absorption grade information.

At this time, the step of measuring the penetration impact amount and the step of generating shock absorption grade information can be re-performed as the durability of the shoe is consumed, and the shoe evaluation information generated in the step of generating shoe evaluation information can include information on the decline time required for the shock absorption grade to decrease as the durability of the shoe is consumed.

In addition, the step of performing the shoe evaluation may further include a step of causing the shoe sole to rub against a friction surface to wear out the durability of the shoe, a step of determining whether the generated shock absorption grade information has decreased compared to previously generated shock absorption grade information, and a step of generating information on the time it took for the shock absorption grade to decrease due to use of the shoe if the shock absorption grade information has decreased.

Additionally, the step of consuming the durability can consume the durability of the shoe by bringing the sole of the shoe into contact with the friction surface of a friction belt driven in a conveyor manner for a set period of time.

Additionally, the step of consuming durability can be accomplished by placing the sole of the shoe on a friction belt so that the sole of the shoe rubs from back to front.

In addition, the step of performing the shoe evaluation further includes a step of determining whether to proceed with the durability consumption step based on the shock absorption grade information generated in the step of generating the shock absorption grade information, and the step of determining whether to proceed may determine not to proceed with the durability consumption step further if the shock absorption grade information is the lowest grade.

Additionally, the step of setting the evaluation conditions may include a step of setting a user's weight, a step of setting a shoe size, a step of setting a usage pattern of one of walking and running, and a step of determining the provided impulse amount based on the set user's weight, shoe size, and usage pattern.

In addition, in the step of measuring the penetration impact, the impact can be applied to the part where the user's heel is worn and the penetration impact can be measured.

In addition, the shoe evaluation method may further include a step of the user terminal determining a decrease in the shock absorption grade of the shoes worn by the user based on shoe evaluation information of the shoes worn by the user, and notifying the user of the decrease in the shock absorption grade of the shoes worn when the shock absorption grade of the shoes worn is decreased.

In addition, the step of notifying a grade downgrade may include a step of calculating the wearing time of the shoes, a step of determining whether the calculated wearing time exceeds the downgrade time according to the current shock absorption grade of the shoes, and a step of outputting a grade downgrade alarm if it is determined that the wearing time has reached the downgrade time.

Additionally, the step of calculating the wearing time can calculate the wearing time based on the elapsed time from the time of first wearing the shoes.

In addition, the step of calculating the wearing time can calculate the wearing time based on a detection signal provided to the user terminal from a separate motion detection sensor mounted on the wearable shoe.

According to the present invention, a shock is applied to the lower or upper surface of the sole of a shoe according to set evaluation conditions, and the shock amount penetrating through the surface opposite to the shock application is measured to calculate the shock absorption amount, and shock absorption grade information of the shoe is generated based on the calculated shock absorption amount, thereby presenting a standardized standard for the shock absorption performance of the shoe, thereby enabling the user to easily and objectively select a shoe having the shock absorption performance he or she needs.

In addition, the present invention can provide a standard for a user to determine when to replace shoes by generating and providing information on the time it takes for the shock absorption level to decrease as the durability of the shoe is consumed, thereby preventing a situation in which the user misses the time to replace shoes and causes strain to the soles, joints, and spine.

In addition, the present invention allows a user terminal to determine a decrease in shock absorption level according to a user's wearing time based on information on the wearer's wearing time of the shoes, and output an alarm to the user regarding the decrease in shock absorption level, so that the user can easily check the exact time to replace the shoes.

The shoe evaluation method according to the present invention will be examined in more detail with reference to the attached drawings below.

FIG. 1 is a functional block diagram of a shoe evaluation system to which a shoe evaluation method according to one embodiment of the present invention is applied.

Referring to FIG. 1, a shoe evaluation system to which a shoe evaluation method according to the present embodiment is applied may be configured to include an evaluation unit (10) that performs a shoe evaluation, a server (30) in which the evaluation results are stored, and a user terminal (50) that communicates with the server (30) to provide shoe evaluation information on shoes worn by the user.

The evaluation unit (10) can perform a shoe evaluation on the shock absorption performance of the shoe sole and generate shock absorption grade information for each shoe.

Specifically, the evaluation unit (10) can calculate a shock absorption rate by comparing the shock amount provided from the upper or lower surface of the shoe sole with the penetrating shock amount measured on the opposite surface of the shock providing surface as the shock amount penetrates the shoe sole. Then, the evaluation unit (10) can determine a shock absorption grade according to the calculated shock absorption rate and generate shock absorption grade information.

For example, the evaluation unit (10) may determine the shock absorption grade as Grade 5 if the calculated shock absorption rate is 40% or more, determine the shock absorption grade as Grade 4 if the calculated shock absorption rate is 30% or more but less than 40%, determine the shock absorption grade as Grade 3 if the calculated shock absorption rate is 20% or more but less than 30%, determine the shock absorption grade as Grade 2 if the calculated shock absorption rate is 10% or more but less than 20%, determine the shock absorption grade as Grade 1 if the calculated shock absorption rate is 1% or more but less than 10%, and determine the shock absorption grade as Grade 0 if the calculated shock absorption rate is less than 1%.

In this way, the determined shock absorption grade information for each shoe is provided to the server (30), and the server (30) can provide the shock absorption grade information for each shoe to the user by disclosing the shock absorption grade information for each shoe. Therefore, through the shock absorption grade information for each shoe provided, the user can easily and objectively select a shoe with the shock absorption performance that he or she needs.

The evaluation unit (10) can generate shock absorption grade information in the initial state of the shoe as well as shock absorption grade information of the shoe whose durability has been consumed, and based on this, can generate decline time information required for the shock absorption grade to decrease according to the use of the shoe. Specifically, the evaluation unit (10) can generate shock absorption grade information every time a predetermined unit period (e.g., 1 month) of wearing time has elapsed after generating shock absorption grade information in the initial state of the shoe. In other words, the evaluation unit (10) can generate shock absorption grade information every time the durability of the shoe is consumed according to the unit period of wearing.

At this time, the durability consumption according to the unit period of wearing of the shoe may be the durability consumption according to the actual wearing of the test user, but may be the durability of the shoe simulated to be consumed according to the durability consumption calculated by calculating the durability consumption according to the unit period of wearing. Specifically, the evaluation unit (10) can calculate the durability consumption according to the unit period of wearing of the shoe, and simulate the calculated durability consumption for a short period of time through a separate durability consumption unit. Here, the durability consumption calculation according to the unit period of wearing may be determined by an experiment, or may be determined based on the average daily wearing time of the shoe, the average number of steps during the unit period, the friction time between the sole of the shoe and the road per step, the average roughness of the road, etc.

Through this process, the evaluation unit (10) can generate information on the time required for the shock absorption grade to drop by one level. At this time, the information on the time required can be generated for each stage. That is, for a shoe whose shock absorption grade information is initially generated as stage 3, information on the time required for the drop from stage 3 to stage 2, information on the time required for the drop from stage 2 to stage 1, and information on the time required for the drop from stage 1 to stage 0 can be generated, respectively.

The evaluation unit (10) generates shoe evaluation information including shock absorption grade information and drop time information for each shoe and provides it to the server (30), and the server (30) can store the provided shoe evaluation information and provide the shoe evaluation information of each shoe stored to the user. Accordingly, the wearer can predict the shock absorption grade of the worn shoe as well as the point in time when the shock absorption grade decreases as the durability of the worn shoe is consumed through the provided shoe evaluation information, and can determine the correct time to replace the worn shoe with reference to this.

The user terminal (50) is a device that the user individually possesses, and when the user inputs shoe information including product information of the shoe to be worn, start time of wearing information, etc., through the user terminal (50), shoe evaluation information about the entered shoe to be worn can be provided from the server (30). In addition, the user terminal (50) that has received the shoe evaluation information can provide the user with shock absorption grade information and drop time information of the shoe to be worn based on the provided shoe evaluation information, and can also determine a drop in the shock absorption grade of the shoe to be worn based on the drop time information of the shoe to be worn and can provide the user with an alarm regarding a drop in the grade of the shoe to be worn.

Various devices that can communicate with the server (30) and input and output information can be applied as the user terminal (50). In particular, a smart watch or smartphone that is advantageous for the user to carry at all times can be applied as the user terminal (50), and the user can use an existing smart watch or smartphone as the user terminal (50) by installing a specific application.

The user terminal (50) can determine the point in time when the level of the worn shoes decreases based on the information on the time of wear and the start time of wear, and provide the user with an alarm about the level decrease. Accordingly, the user can easily check the point in time when the shock absorption level of the worn shoes decreases through the alarm of the user terminal (50) without directly calculating it.

At this time, the user terminal (50) can provide an alarm whenever the shock absorption level of the worn shoes decreases. For example, if the initial shock absorption level of the worn shoes is level 3, an alarm can be provided when the level decreases from level 3 to level 2, an alarm can be provided when the level decreases from level 2 to level 1, and an alarm can be provided when the level decreases from level 1 to level 0.

FIG. 2 is a flowchart illustrating a shoe evaluation method according to one embodiment of the present invention.

Referring to Fig. 2, the shoe evaluation method of the present invention will be examined. When the evaluation unit (10) performs an evaluation for each shoe to generate shoe evaluation information (S10), the server (30) can receive and store the shoe evaluation information (S20). At this time, the server (30) can publicly disclose the stored shoe evaluation information so that users can select shoes by referring to the shoe evaluation information.

The user inputs information about the shoes worn into the user terminal (50), and the user terminal (50) with the input information about the shoes worn can make a request to the server (30) to receive shoe evaluation information about the shoes worn. Then, the user terminal (50) that has received shoe evaluation information about the shoes worn can determine the point in time when the shock absorption level of the shoes worn has decreased based on the shoe evaluation information of the shoes worn and output an alarm (S30).

FIG. 3 is a functional block diagram of an evaluation unit according to one embodiment of the present invention, FIG. 4 is a diagram illustrating an example of an impact provision and measurement according to one embodiment of the present invention, and FIG. 5 is a diagram illustrating an example of a durability wear appearance of a shoe according to one embodiment of the present invention.

As described above, the evaluation unit (10) according to the present embodiment can generate shoe evaluation information including shock absorption grade information and drop time information.

To this end, the evaluation unit (10) may be configured to include a condition setting unit (11) that sets evaluation conditions, an impact calculation unit (12) that calculates the provided impact amount, an impact providing unit (13) that provides the provided impact amount to the shoe, an impact measuring unit (14) that measures the penetrating impact amount, a grade determining unit (15) that determines the shock absorption grade, and an evaluation information generating unit (16) that generates shoe evaluation information, as illustrated in FIG. 3.

The condition setting unit (11) can set detailed conditions for shoe evaluation. Specifically, the condition setting unit (11) can set the user's weight, shoe size, and usage type of either walking or running.

The impulse calculation unit (12) can calculate the provided impulse based on the detailed conditions set in the condition setting unit (11). At this time, the provided impulse can be the provided impulse per unit area. Specifically, the impulse calculation unit (12) can determine the provided impulse in proportion to the user's weight set in the condition setting unit, inversely proportional to the shoe size, and with a stronger intensity when running is set rather than walking.

The shock providing unit (13) can provide the calculated provided shock amount to the lower or upper surface of the sole of the shoe to be evaluated. And the shock measuring unit (14) can measure the penetrating shock amount on the opposite surface of the shock providing surface of the sole of the shoe to which the shock providing unit (13) provides the shock.

More specifically, referring to FIG. 4, the shock providing unit (13) may be equipped with a shock providing module (131) that applies a shock according to a determined amount of shock to the lower or upper surface of the sole of the shoe, and the shock measuring unit (14) may be equipped with a shock measuring sensor (141) that is arranged on the opposite surface of the shock providing surface of the sole to measure the amount of shock that penetrates the sole in the thickness direction by the shock applied by the shock providing module (131).

At this time, when the shock providing module (131) strikes the sole of the shoe downward to provide shock to the lower surface of the sole of the shoe as illustrated in FIG. 4, a separate stand (F1) for holding the shoe (S) so that the lower surface of the sole of the shoe is positioned upward may be provided, and the stand (F1) may be manufactured in the shape of a human leg so that the shoe (S) may be worn. In addition, when the stand (F1) is manufactured in the shape of a human foot, the shock measuring sensor (141) may be placed at a portion of the stand (F1) that comes into contact with the sole of the shoe.

However, most of the shock that occurs when a user walks or walks is concentrated on the heel. Therefore, the shock providing module (131) strikes the heel of the shoe on which the user's heel is worn, and the shock measuring sensor (141) is also placed on the heel of the shoe to measure the amount of shock that penetrates the sole of the heel of the shoe.

The grade determination unit (15) can determine the shock absorption grade of the shoe based on the penetration impact amount measured by the shock measurement sensor (141). Specifically, the grade determination unit (15) receives the penetration impact amount measured by the shock measurement sensor (141), calculates the shock absorption rate through the reduction rate of the penetration impact amount compared to the provided impact amount, and can generate shock absorption grade information based on the calculated shock absorption rate.

The evaluation information generation unit (16) generates shoe evaluation information using the shock absorption grade information determined by the grade determination unit (15). At this time, shoe evaluation information including not only shock absorption grade information but also fall time information can be generated as described above.

To this end, the evaluation unit (10) may additionally be equipped with a friction time calculation unit (17) that calculates the friction time, a durability consumption unit (18) that consumes the durability of the shoe based on the calculated friction time, a decline time judgment unit (19) that determines the decline time of the shock absorption grade, and a termination judgment unit (20) that determines whether the evaluation is terminated.

The friction time calculation unit (17) can calculate the friction time for durability consumption during a predetermined unit period (e.g., 1 month). Specifically, the friction time calculation unit can calculate the friction time based on the average daily wearing time of the shoe, the average number of steps during a unit time, and the friction time between the sole of the shoe and the road surface per step.

The durability consumption unit (18) can wear out the sole of the shoe by friction for the friction time calculated by the friction time calculation unit (17). Specifically, the durability consumption unit (18) can be configured to include a wear conveyor (181) that can be driven in a conveyor manner to cause friction on the sole of the shoe. At this time, as shown in FIG. 5, the wear conveyor (181) can be driven in a conveyor manner by a friction belt (1811) having a friction surface, and can wear out the durability of the shoe by bringing the sole of the shoe into contact with the friction surface of the friction belt (1811) for the friction time. At this time, the friction surface roughness of the friction belt (1811) can be determined based on the average roughness of the road surface on which a typical user wears shoes and walks (for example, the average roughness of a sidewalk block).

A pressurizing means (F2) for pressing the shoe (S) with the friction belt (1811) to bring the sole of the shoe into close contact with the friction surface of the friction belt (1811) may be separately provided, and the pressurizing means (F2) is manufactured in the shape of a human leg so that the shoe (S) can be worn. At this time, the pressurizing means (F2) is configured to be movable in the up-and-down direction, and can press the shoe (S) against the friction belt (1811) by a set distance, and the setting of the close contact distance of the pressurizing means (F2) can be determined so that the close contact strength is improved in proportion to the user's weight set in the condition setting unit (11).

Preferably, the wear-resistant wear portion (18) may be positioned and pressed against the friction belt (1811) so that the sole of the shoe rubs against the ground from back to front, as shown in FIG. 5. This is because the user typically moves forward, and thus the shoe rubs against the ground from back to front.

When durability consumption through the durability consumption unit (18) is completed, shock provision through the shock provision unit (13) and shock measurement through the shock measurement unit (14) are performed again for the shoes whose durability has been consumed, and the grade determination unit (15) can determine the shock absorption grade of the shoes whose durability has been consumed based on the shock measurement performed again. Such processes of durability consumption, shock provision and measurement, and shock absorption grade determination can be repeated two or more times, and the drop time determination unit (19) can generate drop time information when the shock absorption grade determination result of the grade determination unit (15) decreases due to durability consumption of the shoes.

At this time, the drop time information generated by the drop time determination unit (19) can be generated for each level as the actual wearing time required for the shock absorption grade to drop by one level, and the drop time determination unit (19) can generate the drop time information based on the total friction time from the time the previous shock absorption grade was first determined until the shock absorption grade drops by one level.

The termination judgment unit (20) can determine the end of the evaluation of the shoes to be evaluated based on the shock absorption grade determined by the grade judgment unit (15). Specifically, the termination judgment unit (20) can determine the end of the evaluation if the shock absorption grade determined by the grade judgment unit (15) is the lowest grade (grade 0).

When the evaluation information generation unit (16) determines that the evaluation is over in the end judgment unit (20), the evaluation information generation unit (16) can generate shoe evaluation information by collecting the initial shock absorption grade information for the shoes to be evaluated and the drop time information for each grade.

At this time, the shoe evaluation information generated may be shoe evaluation information according to the conditions set by the condition setting unit (11). That is, the shoe evaluation information may be generated by dividing it by weight, shoe size, and usage status such as walking/running. Preferably, the condition setting unit (11) determines a standard shoe size and a standard weight, sets the determined standard shoe size, standard weight, and walking status as standard settings, and the shoe evaluation information may determine the shoe evaluation information generated from such standard settings as the standard shoe evaluation information.

FIG. 6 is a flowchart illustrating a shoe evaluation process according to one embodiment of the present invention in more detail, and FIG. 7 is a diagram illustrating an example of a process for performing grade judgment and durability consumption in a shoe evaluation process according to one embodiment of the present invention.

Referring to Figure 6, the shoe evaluation process is examined. First, in order to perform the shoe evaluation, the condition setting unit (11) can set the evaluation conditions (S11).

When the evaluation conditions are set, the shock calculation unit (12) calculates the provided shock based on the set evaluation conditions, the shock providing unit (13) provides shock to the shoe according to the calculated provided shock, and the shock measuring unit (14) can measure the penetrating shock (S12). In addition, the grade determination unit (15) can generate shock absorption grade information based on the penetrating shock measured by the shock measuring unit (14) (S13).

The drop time determination unit (19) and the durability consumption unit (18) can determine whether the shock absorption grade information generated by the grade determination unit (15) has decreased compared to the previous shock absorption grade information (S14). If the shock absorption grade information has decreased compared to before (S14-Y), the durability consumption unit (18) waits and the drop time determination unit (19) can generate drop time information according to the decrease in the shock absorption grade information (S15). On the other hand, if the shock absorption grade information generated by the grade determination unit (15) has not decreased (S15-N), the drop time determination unit (19) waits and the durability consumption unit (18) can consume the durability of the shoe (S17). And when the durability consumption is finished, the shock providing and measuring process can be performed again. Therefore, in the shoe evaluation process in the present embodiment, the shock absorption grade determination and durability consumption process can be repeatedly performed multiple times as illustrated in FIG. 7.

Meanwhile, when the fall time information is generated, the termination judgment unit (20) can determine whether the shock absorption grade information is the lowest grade (S16). If the shock absorption grade information is not the lowest grade (S16-N), the durability consumption unit (18) can consume the durability of the shoe, and on the other hand, if the shock absorption grade information is the lowest grade (S16-Y), the evaluation information generation unit (16) can generate shoe evaluation information (S19) and end the shoe evaluation process for the target shoe.

Here, the process operation and each judgment in the shoe evaluation process according to the present embodiment are described as being automatically performed in each component of the evaluation unit (10), but some or all of the process operation and each judgment in the shoe evaluation process may be performed by an administrator.

FIG. 8 is a functional block diagram of a user terminal according to one embodiment of the present invention, and FIG. 9 is a diagram illustrating an example of a grade downgrade alarm according to one embodiment of the present invention.

As described above, the user terminal (50) can determine the point in time when the level of the worn shoes is lowered based on the information on the time of wear and the start time of wear, and provide the user with an alarm regarding the level drop.

To this end, the user terminal (50) may be configured to include, as illustrated in FIG. 8, a user information generation unit (51) that generates user information, a shoe information generation unit (52) that generates worn shoe information, a communication unit (53) that transmits and receives various information with the server (30), a storage unit (54) in which various information is stored, a wearing time calculation unit (55) that calculates the wearing time of the worn shoes, a grade decline determination unit (56) that determines a decline in the shock absorption grade of the worn shoes, and an alarm unit (57) that provides an alarm according to a grade decline.

The user information generation unit (51) can generate user information based on user input. At this time, the user information may include the user's shoe size, the user's weight, etc.

The shoe information generation unit (52) can generate worn shoe information based on user input. At this time, the worn shoe information can include product information of the worn shoes worn by the user, information on the start time of wearing the worn shoes, etc.

The communication unit (53) requests shoe evaluation information from the server (30) based on the user information generated by the user information generation unit (51) and the worn shoe information generated by the shoe information generation unit (52), and the server (30) can provide the requested shoe evaluation information. At this time, the shoe evaluation information provided by the server (30) to the user terminal (50) may be shoe evaluation information based on the user's shoe size, weight, and product information of the worn shoe.

The storage unit (54) stores shoe evaluation information provided from the server (30) via the communication unit (53). In this case, if there are multiple pieces of worn shoe information generated by the shoe information generation unit (52), shoe evaluation information for multiple worn shoes can be stored in the storage unit (54). In addition, the storage unit (54) can store worn shoe information generated by the shoe information generation unit (52).

The wearing time calculation unit (55) can generate wearing time information for the worn shoes based on the wearing start time information of the worn shoes.

Specifically, the wearing time calculation unit (55) can determine the elapsed time from the start time of wearing the shoes and calculate the wearing time by applying the wearing time per unit elapsed time stored in advance to the determined elapsed time. For example, the wearing time calculation unit (55) can calculate that 4 hours of wearing time have elapsed every time 24 hours have elapsed.

In addition, the wearing time calculation unit (55) can calculate the wearing time based on a detection signal provided to the user terminal (50) from a separate motion detection sensor (not shown) mounted on the wearable shoe. The wearing time calculation unit (55) can calculate the wearing time by adding up the time during which the detection signal is provided from the motion detection sensor. At this time, the motion detection sensor can be built-in when the shoe is manufactured, but is preferably configured to be detachable from a shoelace or the like so that the user can attach it to each wearable shoe and use it. In addition, the motion detection sensor can be connected to the user terminal (50) through short-range communication using Bluetooth or the like so as to provide a detection signal to the user terminal (50).

Preferably, when entering information on the shoes to be worn, the user can input whether or not the shoes have a motion detection sensor attached, and the wearing time calculation unit (55) can calculate the wearing time based on a detection signal received from the motion detection sensor for shoes to which the motion detection sensor is attached, and can calculate the wearing time based on wearing start time information for shoes to which the motion detection sensor is not attached.

The grade downgrade judgment unit (56) can judge a grade downgrade based on the wearing time information of the worn shoes calculated by the wearing time calculation unit (55) and the shock absorption grade information and downgrade time information of the worn shoes stored in the storage unit (54).

Specifically, the grade downgrade judgment unit (56) can determine that the shock absorption grade has been downgraded when the wearing time reaches the downgrade time based on the downgrade time information required for the current shock absorption grade of the worn shoes to be downgraded by one level and the wearing time information calculated by the wearing time calculation unit (55).

The alarm unit (57) can output a grade drop alarm to the user when the grade drop determination unit (56) determines that the shock absorption grade has dropped. Specifically, when the grade drop determination unit (56) determines that the shock absorption grade has dropped, the alarm unit (57) can output a grade drop alarm to the user that includes product information of the shoes being worn, information on the existing shock absorption grade, and information on the dropped shock absorption grade, as shown in Fig. 9.

In this way, the present invention calculates the wearing time of the shoes by the user terminal (50) to determine a decrease in the shock absorption level, and outputs an alarm to the user when the shock absorption level decreases, so that the user can easily check the exact replacement time of the shoes without having to calculate the wearing time separately.
