Abstract
A golf shoe includes an outsole having a forefoot, a shank, and a heel. A stability ridge is disposed on the outer surface and along the perimeter of the forefoot, the heel, or both the forefoot and the heel. This ridge provides additional traction and stability, particularly when the golfer swings his club to take a shot.

An outsole, comprising:
- a forefoot having an outer surface, an inner edge, and an outer edge;
- a heel;
- a shank disposed between the forefoot and the heel;
- at least one flex groove disposed in the outer surface of the forefoot, extending from the inner edge of the forefoot to the outer edge of the forefoot, and having first and second opposite sides;
- a first ridge disposed on the outer surface of the forefoot and intersecting the at least one flex groove adjacent to the inner and outer edges of the forefoot, respectively, the first ridge being discontinuous at the points of intersection;
- at least one ridge protrusion disposed along the first ridge;
- and
- one or more surface protrusions disposed on the outer surface of the forefoot, each of the surface protrusions including,
- a first side having first and second edges,
- a second side having a first edge that abuts the first edge of the first side at a first angle, the second side having a second edge,
- a third side having a first edge that abuts the second edge of the second side at a second angle,
- a fourth side having a first edge that abuts the second edge of the first side at a third angle, and
- wherein the sum of the first, second, and third angles is less than 180.degree..
