Patent abstract

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.
