FIELD

The present disclosure relates generally to methods, systems and devices for footwear. More specifically, various embodiments of the present disclosure relate to a threaded insert for selective connection to or insertion within preexisting footwear. Certain embodiments provide gripping elements that are operable to be inserted into and/or combined with preexisting footwear and increase the traction, grip, or performance thereof.

BACKGROUND

It is known to provide extensions or cleats with articles of footwear. Some articles of footwear are known to comprise spikes or extensions that are formed with or permanently connected to a bottom portion of the article, such as those commonly used with certain athletic shoes. Other known shoes provide female recesses in a lower portion thereof, and the female recesses are operable to selectively receive a spike or cleat with a male threaded portion. One such device is shown and described in U.S. Pat. No. 8,020,322 to McMullin, which is hereby incorporated by reference in its entirety.

Various known devices that comprises a system having a shoe sole with a pre-formed female portion or threaded receptacle are relatively difficult and expensive to manufacture. Additionally, these devices are also difficult and expensive to manufacture. Additionally, the cleats or spikes that are provided with such systems are useless without the corresponding shoe and appropriately sized pre-formed receptacle.

SUMMARY

Accordingly, there has been a long-felt and unmet need to provide methods, systems and devices of extensions, cleats or gripping elements that can be selectively inserted into a preexisting article of footwear, and wherein the article of footwear is not designed for or otherwise specific to the gripping element(s). As used herein, the terms “cleat” and “gripping element” generally refer to articles that are operable to extend from a lower portion or sole of a shoe to increase traction, friction, grip, and/or performance of a shoe. Although various embodiments of the present disclosure contemplate an extension or gripping element with a plurality of projections, contact points, or traction elements, other embodiments contemplate as few as one projection wherein a single spike or conical member extends from a threaded portion. Accordingly, no limitation with respect to the shape or appearance of devices of the present disclosure is provided herewith. Additionally, no limitation with respect to the intended use or application of methods and devices of the present disclosure is provided. Although certain embodiments of the present disclosure contemplate gripping elements that are well suited for use with golf and provide enhanced traction and grip on turf and golf courses, the present disclosure is not limited to golf or any particular endeavor. Devices of the present disclosure are contemplated for use with golf, hiking, fishing, running, everyday use and any other use or purpose in which increased traction is desired.

In some embodiments, cleats are provided that are relatively easy and cost-effective to manufacture at least as compared with known devices. In certain embodiments, cleats are formed using an injection molding process. In some embodiments, a two-shot mold is provided wherein a first portion of a cleat is formed by injecting a first material. The cleat is fully formed or completed by then injecting a second material. In this manner, a cleat of unitary construction is formed that comprises two different materials with two different material properties. For example, in some embodiments, a first portion is provided that comprise a threaded male extension and a first hardness. A second portion is then formed that comprises a plurality of ground-contacting extensions having a second hardness. In some embodiments, the first hardness is greater than the second hardness.

In various embodiments cleat materials and cleats are provided with one or more colors. The present disclosure contemplates the provision of different cleats that may be useful for different applications, and wherein an intended use or application is indicated by a color. For example, green cleats are contemplated as being provided for use on turf; blue cleats are contemplated as being provided for use on ice, etc.

In some embodiments, a cleat is provided that comprises a first material and a second material. The first material is provided as a base or core member and comprises at least a male threaded member for threadably engaging a shoe (for example).
