Abstract

A golf shoe outsole comprises a thin, flexible base layer having many discrete platforms projecting downwardly from the base layer for providing traction elements. The platforms are separated by channels and open regions to allow the discrete platforms to readily flex relative to one another about the thin base layer, providing enhanced flexibility to the outsole and improved traction performance during a dynamic act such as a golf swing.

First claim

We claim:

1. A golf shoe outsole having a heel end, opposite toe end, lateral side and opposite medial side, the outsole member defining a lateral-medial midline through the outsole that divides the outsole into a forefoot region forward of the midline and a heel-arch region rearward of the midline, the forefoot region having an outer perimeter that extends from the medial side of the midline around the toe end to the lateral side of the midline;
wherein the outsole comprises a thin, flexible base layer that extends across the forefoot region to the outer perimeter;
wherein the forefoot region comprises at least seven platforms disposed around the outer perimeter and projecting downwardly from the base layer, the platforms being separated from one another by portions of the base layer such that channels are defined extending inwardly from the outer perimeter between adjacent pairs of the platforms; and
wherein a first plurality of the platforms each comprise two or more static traction elements extending downwardly from the respective platform, the first plurality of the platforms including at least one platform on the medial side of the midline and at least one platform on the lateral side of the midline; and
wherein a second plurality of the platforms are each configured to mount a dynamic traction element extending downwardly from the respective platform, the second plurality of the platforms including at least one platform on the medial side of the midline and at least one platform on the lateral side of the midline.

2. The outsole of claim 1 , wherein the channels each have a minimum width adjacent the base layer of between 1.0 mm and 4.0 mm.

3. The outsole of claim 1 , wherein the channels on a lateral half of the forefoot each have a minimum width adjacent the base layer of at least 2.5 mm.

4. The outsole of claim 1 , wherein a majority of the channels have a minimum width adjacent the base layer of at least 2.9 mm.

5. The outsole of claim 1 , wherein the base layer has a thickness of less than 2.5 mm and each platform extends downwardly at least 3.0 mm from the base layer.

6. The outsole of claim 1 , wherein the at least seven platforms comprises at least three platforms each configured to mount a dynamic traction element and at least four platforms each comprising four or more static traction elements.

7. The outsole of claim 1 , wherein a group of at least four of the platforms that are adjacent to one another each comprise three or more static traction elements.

8. The outsole of claim 1 , wherein the forefoot region further comprises a central basin that is devoid of traction elements, the central basin bordering at least three of the platforms and communicating with the channels between the platforms and having about the same thickness as the channels between the platforms.

9. A golf shoe outsole having a heel end, opposite toe end, lateral side and opposed medial side, the outsole member defining a lateral-medial midline through the outsole that divides the outsole into a forefoot region forward of the midline and a heel-arch region rearward of the midline;
wherein the forefoot region comprises a plurality of discrete platforms extending downwardly from a thin, flexible base layer that extends across the forefoot region;
wherein the plurality of platforms and the base layer define a forked channel extending below the base layer and between the platforms, the forked channel comprising a stem portion extending inwardly from the medial perimeter of the forefoot, a forward branch extending from the stem portion to the lateral perimeter of the forefoot, and a rearward branch extending from the stem portion to the lateral perimeter of the forefoot rearward of the forward branch;
wherein the forked channel further comprises an intermediate branch that extends from the rearward branch to the lateral perimeter and is positioned between the forward and rearward branches;
wherein a first one of the platforms is positioned along the lateral perimeter between the rearward branch and the intermediate branch, and a second one of the platforms is positioned along the lateral perimeter between the forward branch and the intermediate branch; and
wherein the first one of the platforms or the second one of the platforms is configured to mount a dynamic traction element extending downwardly from the platform.

10. The outsole of claim 9 , wherein the rearward branch and the stem portion are aligned and form a linear channel extending across the forefoot region.

11. The outsole of claim 9 , wherein the forward branch comprises at least three discrete aligned sub-channels, each sub-channel defined by a separate pair of the platforms.

12. The outsole of claim 9 , wherein a platform having a generally triangular base defines a fork between the forward branch and the rearward branch.

13. The outsole of claim 9 , wherein the forked channel is bordered by at least ten platforms extending downward from the base layer.

14. A golf shoe comprising an upper, a midsole, and an outsole, the outsole having a heel end, opposite toe end, lateral side and opposite medial side, the outsole defining a lateral-medial midline through the outsole that divides the outsole into a forefoot region forward of the midline and a rear portion rearward of the midline, the rear portion having a heel region proximate the heel end and an arch region between the heel region and the midline;
wherein the forefoot region and the heel region each comprise at least one dynamic traction element; and
wherein the arch region comprises at least at least two discrete platforms projecting downwardly along the medial side of the arch region with the at least two platforms each including at least one static traction element, and a lateral half of the arch region is free of traction elements.

15. The golf shoe of claim 14 , wherein the outsole comprises a thin, flexible base layer extending the width and length of the outsole, and wherein the the at least two platforms in the arch region project downwardly from the medial side of the base layer.

16. The golf shoe of claim 14 , wherein at least two static traction elements extend downwardly from each platform in the arch region.

17. An athletic shoe outsole having a heel end, opposite toe end, lateral side and opposite medial side, the outsole member defining a lateral-medial midline through the outsole that divides the outsole into a forefoot region forward of the midline and a heel-arch region rearward of the midline, the forefoot region having an outer perimeter that extends from the medial side of the midline around the toe end to the lateral side of the midline;
wherein the forefoot region comprises a plurality of discrete platforms extending downwardly from a thin, flexible base layer that extends across the forefoot region, the plurality of platforms comprising a first group of platforms disposed around the outer perimeter of the forefoot and a second group of platforms clustered at a central portion of the forefoot within the first group of platforms; and
wherein the plurality of platforms and the base layer define a forked channel extending below the base layer and between the platforms, the forked channel comprising a stem portion extending forwardly from the midline between the second group of platforms, a medial branch extending from adjacent a forward end of the stem portion through the first group of platforms to the medial perimeter of the forefoot, a lateral branch extending from adjacent a forward end of the stem portion between the first group of platforms to the lateral
