Golf shoe outsole
Golf shoes having improved outsole constructions are provided. The golf shoes include upper, midsole, and outsole sections. The outsole includes a first set of arc pathways extending along the outsole in one direction. A second set of arc pathways extend along the outsole in a second direction. When the first and second arc pathways are superposed over each other, four-sided tile pieces are formed, and these tiles contain protruding traction members. In one embodiment, the tiles comprise a first protruding traction member, an opposing second protruding traction member, and a non-protruding segment disposed between the first and second traction members. Different traction zones containing different traction members are provided on the outsole. These zones provide improved multi-surface traction. In one embodiment of the outsole, there is no channeling and no trenching of the golf course turf. There is less damage to the golf course for a given amount of traction. In another embodiment, a heel step region without traction members may be provided on the outsole. Additionally, spike receptacles may be provided on the outsole in addition to the traction members.
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, an opposing second protruding traction member, and a non-protruding segment disposed between the first and second traction members,
wherein the outsole further comprises a heel step region, the heel step region being without tile pieces.
2. The golf shoe of claim 1 , wherein the first traction member has a hardness greater than the second traction member.
3. The golf shoe of claim 1 , wherein the first and second traction members each comprise a thermoplastic polyurethane composition.
4. The golf shoe of claim 1 , wherein the non-protruding segment disposed between the first and second traction members comprises an ethylene vinyl acetate composition.
5. The golf shoe of claim 1 , wherein the first and second traction members have substantially the same heights.
6. The golf shoe of claim 1 , wherein the first and second traction members have substantially the different heights.
