照）。2. Description of the Related Art Athletic shoes provided with a midsole are highly deformed at the stepping portion when walking or running, and are liable to cause fatigue to the user. In recent years, there has been a shoe in which the shank is fixed to the lower surface of the midsole to prevent the deformation (for example, see Japanese Patent Application Laid-Open No. 7-079804).

が損なわれる。As an example of such a shank, a strip-shaped or wire-shaped shank is provided on the bottom side of the midsole, so that the rear foot can be easily returned to the front foot.
"Tilt exercise" in which the legs flex slightly while walking, etc.
A shoe sole structure that facilitates the above is known. However, this structure does not provide resistance to in-plane bending along the plane of the sole. On the other hand, if the shank is made into a hard rod shape and the resistance to in-plane bending is increased, the plate-like body fixed before and after the rod-shaped shank becomes an obstacle, and the ease of return is impaired.

As shown in FIG.
As shown in (b), the entire sole 35 starts to land. afterwards,
The center of load of the foot 3 moves inward as if the rear foot 32 rotates inward, as indicated by an arrow A1 in FIG. 6C. Thereafter, the heel starts to float due to the bending of the metatarsophalangeal joint. At this time, first, the third to fifth metatarsophalangeal joints bend first, so that the rear foot portion 32 of the foot is outward as indicated by arrow A2. , And the load center moves to the toe ball 33 outside the foot. Thereafter, when the first and second metatarsophalangeal joints also bend and the foot bends as shown in FIG. 6 (e), the hind foot part 32 of the foot slightly rotates inward as indicated by arrow A1, and the inside of the foot The center of load moves to the toe ball 34 of FIG. 6, and the forefoot is kicked out using the toe ball 34 as the center of load, so that the foot floats in the air as shown in FIG.

As shown in FIGS. 7A and 7B, when the foot lands from the outside of the heel, and the foot is stepped on and the entire sole lands, the heel of the foot rotates to the inside IN. In accordance with this, FIG. , The two rotating blades 1M and 1R slightly rotate toward the inside A1. Subsequently, when the whole sole touches the ground as shown in FIGS. 7B to 7C, the two rotating blades 1M and 1R return to the original state, and the heel of the foot is moved inward IN due to the rigidity of the rear blade 1R. Prevents spinning pronation. Subsequently, in the initial stage of kicking out in FIG. 7D, the heel starts to float. At this time, first, the third to fifth metatarsophalangeal joints are bent, and the toe ball (the front of the foot) The center of load starts to move to the outside of the part. At this time, if the rear foot portion 22 of the sole attempts to rotate outward in response to the movement of the foot, the rear blade 1R rotates outward as shown in FIG. Tolerate. Furthermore,
When the first and second metatarsophalangeal joints also bend and the step 21 begins to float as shown in FIG. 7 (e), as the weight shifts from the little toe ball to the toe ball, as shown in FIG. (B) The two rotating blades 1M and 1R slightly rotate inward, and the feet "tilt".
Is prevented, and the middle wing 1M does not rotate outward, so that the forefoot or middle foot is prevented from being twisted to the outside of the foot, and the force to be applied to the toe ball is applied to the outside of the foot. Prevent escape. Thereafter, when the foot floats in the air, the two blades M and R return to the original origin positions (angles).

(Rear) The wings allow the forefoot movement and the hindfoot movement of the forefoot and the hindfoot to be relatively twisted during walking, while the shank bar prevents the bent part of the foot from bending. Less fatigue. In particular, since a bar-shaped portion or a blade having a large bending rigidity of the shank provides a large resistance to in-plane bending along the plane of the shoe sole, unnecessary deformation of the sole and foot due to the in-plane bending can be prevented. It becomes easy to walk from.

止し得る。The provision of the intermediate blades rotatable inward not only increases the effect of preventing the in-plane bending of the stepping portion, but also when the entire sole lands, and It can allow the rear foot of the foot to rotate inward as it begins to float. In particular, when the foot is stepped on, the forefoot can be prevented from escaping to the toe ball side (outward) and the forefoot can be kicked out with the toe ball as the center of load, preventing foot fatigue I can do it.
