<P>PROBLEM TO BE SOLVED: To provide a shoe sole having a structure that promotes a flapping motion. <P>SOLUTION: The shoe sole is divided into regions R1 to R5 with reference to a border line CL1 of which a vector direction is changed in walking; is structured to properly project, toward a toe direction or a heel direction, a slant face 5 of a projection 1 having a cross section consisting of a trapezoid consisting of an upper sole 2 and a lower sole 3 in parallel, a vertical piece 4 connecting the upper sole 2 and the lower sole 3 and the slant face 5 in the respective regions R1 to R5; and is made stable so as to hardly shake toward a floor reaction force along a track of the flapping motion. <P>COPYRIGHT: (C)2013,JPO&INPIT |
