CROSS REFERENCE

This application is a Continuation-in-Part of U.S. patent application Ser. No. 18/620,499 filed on Mar. 28, 2024, which application is incorporated herein by reference in its entirety for all purposes.

BACKGROUND

The sport of golf can involve a variety of actions that a subject (e.g., a golfer) can perform, such as swinging a golf club, walking a golf course, and/or crouching down to line up a putt. The equipment used to play golf can affect how well or how easily a golfer can perform golf-related actions or movements.

Golf shoes are one example of a piece of equipment that can affect a golfer's performance. In some cases, a functional structure may be embedded in or integrated with the sole assembly of the golf shoes to provide various performance benefits that can enhance a golfer's ability to execute one or more golf-related actions or movements.

SUMMARY

Recognized herein are various shortcomings and disadvantages of conventional shoes with functional structures embedded in or integrated with the sole assembly of the shoes. In some cases, conventional shoes may incorporate a structure such as a plate or an insert into the sole assembly to provide additional control, support, and/or stability for golf-related actions or movements. However, the construction of these shoes may involve lamination, over injection, or the application of adhesives/glues to join various components of the shoe together, which can result in a sole assembly that is overly stiff and relatively inflexible. In some cases, the stiffness and inflexibility of the sole assembly can diminish or even negate the fundamental performance benefits that the functional structures were designed or configured to provide.

The present disclosure addresses the abovementioned shortcomings of conventional shoes by providing various embodiments of shoes with functional structures that can be integrated with the sole assembly without compromising the overall flexibility of the shoe.
