Description

An insole capable of adjusting sole balance and its preparation method

technical field

The invention relates to the field of clothing, in particular, the invention relates to an insole capable of adjusting sole balance and a preparation method thereof.

Background technique

The human foot bears the whole weight of the human body, especially when walking, the heel, arch and sole of the foot bear the weight of the human body in different periods of walking respectively. As a tool to assist the feet to walk, shoes need to provide a balanced support plane for the feet. The joint composed of calcaneus and ankle bone of foot valgus and valgus is slightly deviated, causing unbalanced force on the heel. Long-term unbalanced force will lead to different degrees of wear on the inside or outside of the sole , As a result, the plane of the inner sole of the shoe cavity is inclined, which aggravates the uneven force on the foot. Most of the insoles on the market cannot fully consider the unbalanced force of the calcaneus, let alone make dynamic adjustments based on the wear of the sole, so that as the wear of the sole increases, the inclination angle of the insole plane increases. Larger, leading to increased valgus or varus of the calcaneus.

test case

The insole of the present embodiment 1 was placed in the shoe cavity, and the subjects were allowed to try them on respectively. And collect the subjective feelings and evaluations of the subjects:

The shoes that the subjects tried were: flat shoes with no obvious wear on the heel, flat shoes with severe wear on the heel (outside or inside), and flat shoes with the insole of this embodiment and no obvious wear on the heel 1. Wear the flat shoes that add present embodiment insole and the heel is seriously worn (outside or inside). According to the condition of the sole of the wearer, adjust the padding at the bottom of the insole according to the embodiment scheme, and carry out the interval test with the flat shoes without the insole of the embodiment.

The process of the subject trying on is: standing still for 5 seconds → walking back and forth at a normal speed (20% amplitude fluctuation control of speed 0.6m/s) along the straight passage (5-8m), reciprocating 3 times → on the force plate Stand on one foot (at least 3 seconds) → go up the stairs through the force plate → go down the stairs and pass the force plate. After the try-on, a subjective questionnaire survey was conducted, and the feeling of wearing the shoes was recorded on the corresponding state of the comfort questionnaire.

The subject marked the subjective feeling choice on the corresponding line segment (anywhere on the line segment can be used). Finally, the comfort of "an insole with independent inner and outer arch support" is sorted out and analyzed.

The questionnaire uses a 5-point comfort evaluation scale (as shown in Figure 6). 0 means very comfortable, 1 means comfortable, 2 means moderately comfortable, 3 means uncomfortable, and 4 means very uncomfortable. Subjects can mark their subjective feelings anywhere on the line according to their own feelings. The results are shown in Table 1-3 below:
