PURPOSE: A mid-sole with round walking function is provided to have a mid-sole part of hardness level between mid-sole part and front-sole part, thereby obtaining walking promoting force by repulsive elasticity at the same time. CONSTITUTION: A mid-sole(12) consists of a front sole part(22), a back sole part(23), and a mid-sole part(21). The mid-sole part has the shore hardness of 30-80 Hs, and consists of one shape of arch, arc, and a square. The back-sole part has the shore hardness of 15-45 Hs, absorbs impact by generating enough compression due to weight during walking, and of which floor is formed to be horizontal with ground. The front-sole part has the shore hardness of 20-60 Hs, generates compression at walking thereby promoting walking by repulsive elasticity at separating from ground, and of which floor is formed to be horizontal with the ground. |
