Abstract
Golf shoes having improved constructions are provided. The golf shoes include upper, midsole, and outsole sections. The upper may be made of a soft, breathable leather material. The midsole includes an upper region formed from a first material such as a foamed ethylene vinyl acetate (EVA); and a lower region formed from a second material such as a foamed ethylene vinyl acetate (EVA), wherein the materials have different hardness levels. A fiber-reinforced composite plate such as, for example, a carbon fiber plate is disposed in the midsole. The outsole contains different traction members arranged in a precise geometric structure that helps provide improved stability and traction.
Claims17
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 midsole comprising:
- i) an upper region formed from a first material and having an upper surface;
- ii) a lower region formed from a second material and having a lower surface;
- and iii) a fiber-reinforced composite plate disposed between the upper and lower regions, wherein a Shore C hardness of the second material is greater than a Shore C hardness of the first material,
- wherein the composite plate is positioned so that it has a first end in the forefoot region of the midsole and a second end in the rear-foot region of the midsole, wherein a forefoot distance from the first end of the composite plate to the lower surface of the midsole is less than a rear-foot distance from the second end of the composite plate to the lower surface of the midsole rear-foot region
- wherein the outsole comprising a Track A containing a first set of traction members, and a Track B containing a second set of traction members, wherein Track A extends from a periphery of the medial side of the forefoot and through the mid-foot region to the periphery of the lateral side of the rear-foot region and Track B extends from the periphery of the lateral side of the forefoot and through the mid-foot region to the periphery of the medial side of the rear-foot region such that Tracks A and B criss-cross each other in the mid-foot region;
- wherein Track A has an outer edge and an inner edge and Track B has an outer edge and an inner edge such that one of Track A and Track B crosses over the other.
