Abstract (en)
[origin: WO2008044854A1] A footwear sole having a dual- structure midsole, in which a seesaw movement can be performed to enhance an exercise effect during walking. The seesaw-motion footwear sole includes a main midsole having a convex projection in the central portion of the underside thereof to define a walking axis; a sub-midsole coupled to the underside of the main midsole and made of a softer material than that of the main midsole in order to exhibit a primary shock absorbing function, wherein the sub-midsole allows the main midsole to perform a seesaw movement on the basis of the walking axis in backward and forward directions during walking; and an outsole coupled to the sub-midsole. The seesaw-motion footwear sole can be applied to a variety of shoes such as running shoes, and can advantageously provide an excellent exercise effect, which is superior to that provided by heelless shoes of the prior art.
