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;
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;
the outsole comprising a first set of arc pathways having a center point located on the medial side of the forefoot region and extending along the forefoot region in a longitudinal direction, the radius of each arc pathway increasing from the center point as the arcs extend along the forefoot region;
a second set of arc pathways having a center point located on posterior end of the forefoot region and extending along the forefoot region in a transverse direction, the radius of each arc pathway increasing from the center point as the arcs extend along the forefoot region;
so that when the first and second set of arc pathways are superposed over each other, intersecting points between the first and second set of arc pathways are formed; the intersecting points forming four-sided tile pieces on the surface of the forefoot region, 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 forefoot region further comprises at least three spike receptacles.
2. The golf shoe of claim 1 , wherein the first and second traction members have a hardness, the hardness of the first traction member is greater than the hardness of 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 different heights.
6. The golf shoe of claim 5 , wherein the first and second traction members each have a height, the height of the first traction member is about 0.25 to 1 mm greater than the height of the second traction member.
7. The golf shoe of claim 1 , further comprising a heel step region adjacent the forefoot region on the outsole, the heel step region not being provided with tile pieces.
8. The golf shoe of claim 1 , wherein the rear-foot region further comprises at least three spike receptacles.
