Propulsive sole for impact distribution and round walking
A shoe sole 3 of the present invention comprises a midsole 4 and an outsole 5 , in which the outsole 5 includes a cushion member 10 formed beneath the midsole 4 , in a shape of a series of zigzags, with a determined thickness and width. The cushion member may disperse the wearer's weight uniformly to the whole area of the shoe sole and may provide comfortable deformation of the shoe sole according to the wearer's walking behavior due to spaces defined in the cushion member. Since the cushion member gets opened and shrunk repeatedly while walking, the wearer can propel one's round walking, thereby that the shoe sole can reduce the fatigue of the wearer's feet and protect the wearer's joints like ankles and knees safely.
1. A shoe sole with propelling function for impact dispersion and round walking, the shoe sole comprising:
a midsole;
and an outsole,
wherein the outsole includes a cushion member formed on a bottom of the midsole, wherein the cushion member extends in a continuous zigzag shape along the bottom of the midsole with peaks of the zigzag shape transitioning into troughs of the zigzag shape in a lateral direction across a width of the midsole.
2. The shoe sole of claim 1 , wherein the cushion member provides a space defined inside a zigzag curved section to have one lateral opening, thereby to disperse impact.
3. The shoe sole of claim 2 , wherein zigzag curved sections at both lateral sides in the outsole are relatively thicker and wider than a middle section in the outsole.
4. The shoe sole of claim 2 , wherein the opening of the space is narrower than inside of the space.
5. The shoe sole of claim 1 , wherein the thickness of the cushion member increases gradually from a medial portion to a heel portion, and
the thickness of the cushion member increases and then decreases gradually from the medial arch portion to a toe portion.
6. The shoe sole of claim 1 , wherein toe and heel portions of the cushion member are formed wider than a middle portion thereof.
7. The shoe sole of claim 1 , wherein the zigzag shaped cushion member is provided independently with a support member which is formed on the cushion member in a shape of a sole of the foot.
8. The shoe sole of claim 7 , wherein the midsole is provided on the cushion member.
9. The shoe sole of claim 1 , further comprising a non-slip pad attached on the whole or part of bottom of the cushion member.
10. The shoe sole of claim 1 , wherein the cushion member is shaped in a series of zigzags from the heel portion to the toe portion.
