In this embodiment, the cushion material 41 is made of a material with excellent impact absorption properties, such as silicone rubber, and has an appropriate thickness. The cushion material 42 is made of a stretchable material and has a shock absorbing effect. The cushioning material 42 may be made of the same material as the material forming the supporter body 1 (the heel covering part 2 and the dorsum of the foot covering part 3). Note that the material and thickness of the cushioning materials 41 and 42 can be appropriately selected and changed in various ways. Further, instead of the configuration including two cushioning materials 41 and 42, a configuration including a single cushioning material or a configuration including three or more cushioning materials may be used.

The auxiliary member 5 is made of a stretchable material and is arranged so as to overlap the peripheral upright portion 22 of the heel covering portion 2 . Specifically, the auxiliary member 5 overlaps a range extending from the rear end (rear upright piece 221) of the peripheral edge upright portion 22 to both left and right sides (left side upright piece 222 and right side upright piece 223). In this embodiment, the auxiliary member 5 is made of, for example, a rubber band, and is more stretchable than the supporter main body 1 (the heel covering part 2 and the dorsum of the foot covering part 3). Further, in this embodiment, the rear end of the auxiliary member 5 at the center in the longitudinal direction is fixed to the rear end (rear upright piece 221) of the peripheral edge upright part 22 by suture, and the left side auxiliary member extends leftward from the fixed part. 51, and a right side auxiliary piece 52 extending to the right side.

Therefore, the tip portion of the left auxiliary piece 51 (the left end of the auxiliary member 5) is attached to the left upright piece 222 so that its position can be changed. Furthermore, the fastener portion 54 can be removably attached to an appropriate position on the right side upright piece 223 (a hook-and-loop fastener loop is formed on the outer surface) of the peripheral edge upright portion 22 . Therefore, the distal end portion of the right side auxiliary piece 52 (the right side end of the auxiliary member 5) is attached to the right side upright piece 223 so that its position can be changed.

Next, the operation of this embodiment will be explained.

The foot supporter A1 of this 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 an imaginary line.

The foot supporter A1 includes a supporter body 1 including a heel covering part 2 and a dorsal foot covering part 3, and a sole corresponding part 21 of the heel covering part 2 is provided with cushioning materials 41 and 42. Thereby, it is possible to reduce the impact on the heel region when stepping on the foot.

The supporter main body 1 (the heel covering part 2 and the dorsal foot covering part 3) is made of a stretchable material. The heel covering part 2 has a peripheral edge standing part 22 that stands up from the peripheral edge extending from both left and right sides of the sole corresponding part 21 to the rear, and this peripheral edge standing part 22 has a cylindrical shape with the dorsum of the foot covering part 3. According to such a configuration, when the foot supporter A1 is worn on the foot, the peripheral edge standing portion 22 and the dorsal foot covering portion 3 are extended. As a result, a contractile force acts on the peripheral edge standing portion 22 as shown by the arrow N1 in FIG. 5, and a contractile force acts on the dorsal foot covering portion 3 as shown by the arrow N2 in the same figure, so that the foot supporter A1 fits from the heel to the dorsum of the foot. On the other hand, the ankle region of the foot is not covered by the foot supporter A1 and is exposed. Therefore, the area around the ankle can be moved without any hindrance, and even if worn for a long time, there will be no pain in the foot.

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 disposed so as to overlap with the peripheral edge upright portion 22 in a range extending from the rear end thereof to both left and right sides. According to such a configuration, when the foot supporter A1 is attached to the foot, the auxiliary member 5 is expanded, and a contraction force acts on the auxiliary member 5 as shown by the arrow N3 in FIG. Therefore, the above-mentioned contraction force of the peripheral edge standing portion 22 (arrow N1) and the contraction force of the auxiliary member 5 (arrow N3) work together to prevent the peripheral edge standing portion 22 (heel covering portion 2) from coming off from the heel region. At the same time, displacement of the foot supporter A1 can be prevented.

In this embodiment, the auxiliary member 5 is attached such that at least one of its left and right ends (the tip of the left auxiliary piece 51 and the tip of the right auxiliary piece 52) is movable relative to the peripheral edge standing portion 22. According to such a configuration, the degree of expansion of the auxiliary member 5 and the contractile force acting on the auxiliary member 5 when the foot supporter A1 is attached to the foot can be adjusted as appropriate.

In this embodiment, the rear end of the auxiliary member 5 is fixed to the peripheral edge upright part 22 (rear upright piece 221), and both left and right ends (tip portions of both the left side auxiliary piece 51 and the right side auxiliary piece 52) are erected on the peripheral edge. It is attached to the portion 22 (left side upright piece 222 and right side upright piece 223) so that its position can be changed. According to such a configuration, the attachment position of the auxiliary member 5 to the peripheral edge upright 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, it is possible to finely adjust the contraction force by the auxiliary member 5 on both the left and right sides.

The foot supporter A1 of this embodiment is provided with a length adjusting means for adjusting the length of the foot dorsum covering portion 3 in the left-right direction. According to such a configuration, the length of the dorsal foot covering part 3 can be adjusted to match the size of the user's foot, and the contractile force of the dorsal foot covering part 3 can be adjusted.

The length adjusting means in the dorsal foot covering portion 3 is constituted by 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 removed from the foot, and the foot supporter A1 is easy to use.

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

In the foot supporter A2, the auxiliary member 5 has a rear end at the center in the longitudinal direction that is not fixed to the peripheral upright portion 22 (rear upright piece 221), and is composed of a series of auxiliary pieces 55 that extend from the rear end to both sides in the left and right directions. be done. The left end of the auxiliary piece 55 is a fixing part 56 fixed to the left side upright piece 222 of the peripheral edge upright part 22 by stitching. A fastener portion 57 is attached to the right end of the auxiliary piece 55. The fastener part 57, like the fastener part 54 in the foot supporter A1, can be removably attached to an appropriate position of the right side upright piece 223 (with a hook-and-loop fastener loop formed on the outer surface) of the peripheral upright part 22. A loop portion 58 is fixed to the rear upright piece 221 of the peripheral edge upright portion 22 by stitching, and the auxiliary member 5 (auxiliary piece 55) is passed through the loop portion 58.

The foot supporter A2 of this embodiment also has the same effects as the foot supporter A1 described above. Further, the auxiliary member 5 is attached so that its right end (the right end of the auxiliary piece 55) can be changed in position relative to the peripheral edge upright portion 22 (right side upright piece 223). According to such a configuration, the degree of expansion of the auxiliary member 5 and the contractile force acting on the auxiliary member 5 when the foot supporter A1 is attached to the foot can be adjusted as appropriate.

Although specific embodiments of the present invention have been described above, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the invention. The specific configuration of each part of the foot supporter according to the present invention can be modified in various ways.

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