Therefore, the tip portion of the right side auxiliary piece 52 (the right end of the auxiliary member 5) is repositionably attached to the right side standing piece 223.

Next, the operation of this embodiment will be described.

The foot supporter A1 of the present embodiment is used by being attached to the foot, for example, when practicing kendo. FIG. 5 is a side view showing a state in which the foot supporter A1 is attached to the foot, and the foot is represented by a virtual line.

The foot supporter A1 includes a supporter main body 1 including a heel covering portion 2 and a foot back covering portion 3, and cushioning materials 41 and 42 are provided on the sole corresponding portion 21 of the heel covering portion 2. As a result, the impact on the heel portion when the foot is stepped on can be alleviated.

The supporter body 1 (heel covering portion 2 and foot back covering portion 3) is made of an elastic material. The heel covering portion 2 has a peripheral edge standing portion 22 that stands up from the peripheral edge extending from both the left and right sides of the foot sole corresponding portion 21 to the rear, and the peripheral edge standing portion 22 has a tubular shape with the foot back covering portion 3. According to such a configuration, when the foot supporter A1 is attached to the foot, the peripheral edge standing portion 22 and the foot back covering portion 3 are extended. As a result, a contraction force acts on the peripheral edge standing portion 22 as shown by an arrow N1 in FIG. 5, and a contraction force acts on the foot back covering portion 3 as shown by an arrow N2 in the same figure. A1 fits so as to wrap around the back of the foot from the heel. On the other hand, the ankle portion of the foot is exposed without being covered by the foot supporter A1. Therefore, the area around the ankle can be moved without any trouble, and the foot does not hurt even if it is worn for a long time.

An auxiliary member 5 is provided on the peripheral edge standing portion 22 of the heel covering portion 2. The auxiliary member 5 is made of a stretchable material, and is arranged so as to overlap in a range extending from the rear end of the peripheral edge standing portion 22 to both the left and right sides. According to such a configuration, when the foot supporter A1 is attached to the foot, the auxiliary member 5 is extended, and a contraction force acts on the auxiliary member 5 as shown by an arrow N3 in FIG. Therefore, the cooperation between the contraction force of the peripheral edge standing portion 22 (arrow N1) and the contraction force of the auxiliary member 5 (arrow N3) prevents the peripheral edge standing portion 22 (heel covering portion 2) from coming off from the heel portion. At the same time, it is possible to prevent the foot supporter A1 from being displaced.

In the present embodiment, at least one of the left and right ends (the tip portion of the left auxiliary piece 51 and the tip portion of the right auxiliary piece 52) of the auxiliary member 5 is attached so as to be repositionable with respect to the peripheral edge standing portion 22. According to such a configuration, the degree of extension of the auxiliary member 5 and the contraction force acting on the auxiliary member 5 when the foot supporter A1 is attached to the foot can be appropriately adjusted.

In the present embodiment, the rear end of the auxiliary member 5 is fixed to the peripheral edge standing portion 22 (rear standing piece 221), and both the left and right ends (the tip portions of both the left side auxiliary piece 51 and the right side auxiliary piece 52) stand on the peripheral edge. It is attached to the portion 22 (left side standing piece 222 and right side standing piece 223) so as to be repositionable. According to such a configuration, the mounting position of the auxiliary member 5 with respect to the peripheral edge standing portion 22 can be changed independently for the left side (left side auxiliary piece 51) and the right side (right side auxiliary piece 52). Therefore, the contraction force of the auxiliary member 5 can be finely adjusted on both the left and right sides.

In the foot supporter A1 of the present embodiment, a length adjusting means for adjusting the length of the foot back covering portion 3 in the left-right direction is provided. According to such a configuration, the length of the foot back covering portion 3 can be adjusted so as to match the size of the user's foot, and the contraction force of the foot back covering portion 3 can be adjusted.

The length adjusting means in the foot back covering portion 3 is composed of a hook-and-loop fastener. According to such a configuration, the foot supporter A1 can be easily attached to the foot and the foot supporter A1 can be easily removed from the foot, which is excellent in usability.

FIG. 6 shows another example of the foot supporter according to the present invention. In the foot supporter A2 of the present embodiment, the configuration of the auxiliary member 5 is different from that of the above-mentioned foot supporter A1. In FIG. 6, the same or similar elements as those in the above embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

In the foot supporter A2, the auxiliary member 5 is composed of a series of auxiliary pieces 55 extending from the rear end to the left and right on both sides, without the rear end at the center in the longitudinal direction being fixed to the peripheral edge standing portion 22 (rear standing piece 221). Will be done. The left end of the auxiliary piece 55 is a fixing portion 56 fixed to the left standing piece 222 of the peripheral edge standing portion 22 by suture. A fastener portion 57 is attached to the right end of the auxiliary piece 55. Similar to the fastener portion 54 in the foot supporter A1, the fastener portion 57 can be detachably attached to the right side standing piece 223 of the peripheral edge standing portion 22 (a loop of a hook-and-loop fastener is formed on the outer surface). A loop portion 58 is fixed to the rear standing piece 221 of the peripheral edge standing portion 22 by suture, and an auxiliary member 5 (auxiliary piece 55) is passed through the loop portion 58.

The foot supporter A2 of the present embodiment also exerts the same action and effect as the above-mentioned foot supporter A1. Further, the auxiliary member 5 is attached so that the right end (the right end of the auxiliary piece 55) can be repositioned with respect to the peripheral edge standing portion 22 (right side standing piece 223). According to such a configuration, the degree of extension of the auxiliary member 5 and the contraction force acting on the auxiliary member 5 when the foot supporter A1 is attached to the foot can be appropriately adjusted.

Although the specific embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications can be made without departing from the idea of the invention. The specific configuration of each part of the foot supporter according to the present invention can be freely redesigned.

In the above embodiment, the configuration in which the loop of the surface fastener is formed over the entire surface of the supporter main body 1 facing the outside has been described, but the present invention is not limited to this. For example, instead of forming a loop on the outer surface of the supporter main body 1, a fastener portion having a loop formed on the outer surface of the supporter main body 1 may be attached.
