What is claimed is: 
     
       1. A sporting shoe comprising: an upper housing;   a relatively rigid sole disposed beneath and secured to said housing.[., the bottom surface of said sole being convexly arcuately curved in a longitudinal direction so that its longitudinal center portion provides a pedestal, whereby when a runner wearing the shoe lands upon a running surface with the heel portion of said sole the runner's foot and the shoe will then roll forward in a pivotal movement about said pedestal.].;   a first resilient auxiliary sole member secured to the heel portion of said rigid sole; and   a second resilient auxiliary sole member secured to the toe portion of said rigid sole.Iadd.; and   the bottom surface of said rigid sole being convexly arcuately curved in a longitudinal direction so that its longitudinal center portion provides a pedestal;   whereby when a runner wearing the shoe lands upon a running surface by engaging same with said first auxiliary sole member, the runner's foot and the shoe will then roll forward in a pivotal movement about said pedestal.Iaddend..   
     
     
       2. A shoe as in claim 1 wherein said auxiliary sole members are spaced apart sufficiently to leave said pedestal exposed to direct contact with the running surface.
