发明名称 Shoe sole
摘要 A primary pivot pad (28) is positioned on the sole (12) of a shoe (10) below the ball region of the user's foot. A secondary pivot pad (30) is positioned on the sole (12) forwardly of the primary pivot pad (28). A second secondary pivot pad (20, 20') is positioned on the sole (12) both rearwardly and laterally inwardly from the primary pivot pad (28). The secondary pivot pad (20) may be positioned primarily rearwardly and somewhat laterally (FIG. 2) or may be positioned primarily laterally and only slightly rearwardly (FIG. 13). Each pivot pad presents a downwardly directed pivot surface having a pivot center. The primary pivot pad (28) extends into each secondary pivot pad (20, 20', 30) and truncates each secondary pivot pad (20, 20', 30).
