A shoe sole for enhanced turning traction and release characteristics with an instep and an out step and further having a toe section and a heel section, the toe section bearing from two to a plurality of downwardly asymmetrically extending vacuum limiting traction arrays. Toe traction arrays are of generally circular basis, generally concentric with a point in a vertical axis with the balance point of the shoe sole and with the asymmetric extension from a plane comprising the shoe sole affording greater angle to the instep than the out step. This differential of angle allows improved turning characteristics with less turning strain for the wearer. In a further aspect of the invention, the heel section of the shoe bears vacuum limiting traction arrays to enhance the traction characteristics of the shoe when the shoe sole is applied generally flush with the traction surface.
