1. A golf shoe comprising:
an upper,
an outsole,
and a midsole connected to the upper and outsole, the upper, midsole, and outsole each having forefoot, mid-foot, and rear-foot regions and lateral and medial sides; and
the outsole comprising a first set of spiral pathways (A), each spiral pathway having a point of origin with a plurality of spiral segments radiating from that point, and wherein each segment has a different degree of curvature and contains sub-segments;
a second set of spiral pathways (B), each spiral pathway having a point of origin with a plurality of spiral segments radiating from that point, and wherein each segment has a different degree of curvature and contains sub-segments; and
the first set of spiral pathways (A) being normal and the second set of spiral pathways (B) being an inverse of the first set of spiral pathways, so that when the spiral pathways are superposed over each other, the sub-segments of spiral segments from set (A) and the sub-segments of spiral segments from set (B) form four-sided tile pieces on the surface of the outsole, the tile pieces containing traction members, wherein a plurality of tile pieces comprise a first protruding traction member,
four zones provided in the outsole, a first lateral forefoot region zone, a second medial rear-foot region zone, a third medial forefoot region zone, and a fourth lateral rear-foot region zone, the first, second, third and fourth zones having at least two different hardness values.
