Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a sole provided as an insole or midsole suitable for footwear, mainly athletic shoes.

<Prior art> Conventional insoles and insoles are made of a single material such as cellular rubber or cellular resin and have unevenness on the sole-contacting surface that mimics the unevenness of the sole of the foot, or the sole of these materials. Products with a thin woven fabric attached to the side surface were provided.

<Problems to be solved by the invention> The above-mentioned conventional single material, the insole and insole that simply have a sole-contacting surface, are formed into an uneven shape that follows a certain sole of the foot. However, the unevenness of the soles of individual shoe wearers varies widely, so it is impossible to mold the soles of every shoe wearer. Not only can the foot not be sufficiently supported and the foot may slip, causing injury to the head of the toe, but also the toe and sole may be injured due to strong pressure stimulation caused by irregularities such as the insole. Ta.

In addition, insoles or insoles made of cellular rubber or cellular resin and bonded with woven or knitted fabric on the side along the sole of the foot with adhesive etc. can be used to create irregularities such as textures or stitches on the flat sole of the foot. Therefore, they merely try to prevent the wearer's feet from slipping during normal walking, and for that reason, when wearing athletic shoes for running, etc., which require strenuous footwork, especially strong kicking force from the toes, However, it is not possible to sufficiently prevent the toes from slipping, which not only reduces running speed but also causes damage to the toes.

The present invention prevents the foot of the shoe wearer from slipping on the sole-supporting surface such as the insole or insole of the footwear mentioned above, adapts to the footwork of the foot, prevents the reduction of stiffness, and furthermore This prevents damage to the fingers.

<Means for solving the problem> In order to solve the above-mentioned problem, the present invention provides shoes with extremely high flexibility and resilience, which have an outer peripheral portion 2 that is larger than the outer peripheral edge 1 of the sole of the shoe wearer. Just by cutting a good rubber-like elastic body into a bottom shape,
To provide a sole A that can fit and hold a shoe wearer's foot without providing a groove in the shape of a footprint such as the sole of the shoe wearer's foot in advance.

<Embodiment> As shown in FIG. 1, the sole A of the footwear of the present invention is made of a rubber-like elastic material such as polyurethane foam in a part slightly larger than the outer peripheral edge 1 of the sole of the foot B of the shoe wearer. It is cut into a bottom shape with 2. Therefore, as shown in FIGS. 2 and 3, when the sole A of the present invention is pressed by the foot B of the shoe wearer, the sole supporting surface 3 of the sole A is pressed by the foot B and It sinks into a sole-shaped depression 6 that follows the unevenness of the sole of foot B, but there is still 3 to 5 mm below foot B (between the sole support surface 3 and the lower surface 4). The outer peripheral edge 1 of the sole is formed on two sides of the outer peripheral part on the outer periphery, and is surrounded by the outer peripheral wall 5 of the sole-shaped recess 6. There is.

In addition, the base A is flexible and deforms into an uneven shape that follows the sole of the foot according to the pressure applied, for example, from the foot B, but when the pressure from the foot B is removed, it returns to its old shape. It is molded from a rubber-like elastic material with extremely good flexibility and resilience that does not cause permanent deformation even after repeated deformation and restoration, and even when the sole supporting surface 3 is compressed by the pressure of the foot. It is preferable to cut it to a thickness of about 10 mm or more and less than 20 mm so that there is still a thickness of about 3 mm to 5 mm between the sole supporting surface 3 and the lower surface 4.

<Effects of the invention> After the sole A of the present invention is inserted as an insole or an insole into the sleeve of footwear, especially athletic shoes, the foot of the shoe wearer is placed on the sole A inside the sleeve. be given At this time, when the athletic shoes land or land on the floor, the sole A
is compressed between foot B and the sole of the shoe, and in particular, the surface 3 along the sole of the sole A has an uneven shape that follows the unevenness of the sole of foot B, as shown in FIGS. 2 and 3. Although it is compressed, it still has a thickness of about 3 mm or more at the smallest point between the surface along the sole of the foot 3 and the lower surface, so it not only can reduce the impact from the ground and prevent injury to the foot B, At this time, the base A is as shown in Figures 2 and 3.
As shown in the figure, all the outer peripheral edges 1 of the foot B are surrounded by the inner peripheral wall 5 of the outer peripheral part 2 (the foot B is sunk inside the base A), so that the foot B can be Even if the foot B tries to move in the direction, it is completely inhibited by the outer circumferential wall 5 of the sole-shaped recess 6 of the outer peripheral portion 2 and the sole-shaped recess 6, and does not slip. This prevents your fingers from colliding with the shoes and causing scratches on your shoes (so-called shoe blisters), and since the toes do not slip, you can use the strong force of the toes to help you run. It helps increase speed and makes footwork smoother.

Claims (1)

[Scope of Claim for Utility Model Registration] 1. Having an outer peripheral part 2 that is larger than the outer peripheral edge 1 of the sole of the footwear wearer, and which forms a sole-like depression when the foot B of the shoe wearer applies pressure. 6 and the outer circumferential wall 5 of the recess 6, the sole is made of a rubber elastic body with extremely good flexibility and restorability, and can support the foot B so as to wrap it therein. 2. The base according to claim 1, wherein the rubber-like elastic body has a thickness of 10 mm or more and less than 20 mm. 3. The base according to claim 1 or 2, wherein the rubber-like elastic body is made of polyurethane foam that hardly causes permanent deformation.
