ABSTRACT:
A sole for a sport shoe to provide increased traction and stability comprises a main sole member having a heel portion including a heel curve and a forward position underlining the ball of the foot including a toe curve. The main sole member has a center point defined by the intersection of an optical center line and a transverse line. The optical center line and the transverse line defines four quadrants, namely, a forward lateral, a forward medial, a rearward lateral, and a rearward medial. A forward medial cleat is located generally on a first radial line 30 degrees to the medial side of the optical center line about the center point and spaced generally 44% of the length of the transverse line from the center point. A rearward lateral cleat is located on a second radial line generally 130 degrees to the lateral side of the optical center line about the center point and spaced generally 59% of the length of the transverse line from the center point. A rearward medial cleat and a forward lateral cleat are respectively located in the rearward medial quadrant and the forward lateral quadrant.
