Benefits of technology
The present invention provides a stronger and more durable heel tip for high-heel wearers that can be used for several years without wearing out. The heel tip is made of longer-wearing, resilient materials that protect the body from the harmful shock waves that cause chronic injuries. The micro honeycomb structure also decreases the amplitude of the high frequency forces and their ability to propagate up into the body, thus eliminating chronic pain and injuries that can diminish the high-heel wearer's ability to function at a normal level. Additionally, the heel tip is securely attached to the heel and aligns with it, using various combinations of anti-rotation, securing, and alignment promoting features. The invention also provides a threaded insert or expansion anchor to prevent rotation or slippage of the heel tip, and the option to easily remove it for replacement or swapping with a different style.
Problems solved by technology
Currently, there is no commercially available heel tip that does not wear out within a few weeks of use.

Embodiment Construction
[0048]FIG. 1 is a perspective view of an example high heel footwear 100 having a relatively narrow heel that incorporates a heel tip assembly 102 according to an aspect of the present disclosure. The term “footwear” encompasses shoes, boots, sandals, flip flops, and any other apparatus worn on the foot and designed or intended to be worn by either men or women or both. The term “high heel” has its ordinary meaning to those skilled in the art of footwear, and those of ordinary skill in the art of footwear will appreciate the dimensions and characteristics of a footwear item having a high heel. For example, stiletto type heels can have a heel height of about 4-6 inches or even higher. Squatter, high heel boots (including those worn by men), for example, can have a heel height of about 3-4 inches. According to some aspects, a minimum heel height to qualify as a high heel is about 2 inches. The present disclosure also contemplates so-called platform footwear, so long as there is a disti...

Abstract
A high heel footwear including a top lift having any one or more of a securing feature, an anti-rotation feature, an alignment feature, and a cushioning feature. The securing feature secures the top lift to the heel of the footwear so that during usage, the top lift remains securely in place against the heel stem. The anti-rotation feature prevents rotation of the top lift relative to the heel, particularly when a twisting force is applied to the top lift by the footwear wearer. The alignment feature co-aligns the top lift to the heel, a particularly useful feature when the heel has an irregular or non-regular cross-section. A cushioning feature is also provided, for example, in the form of a honeycomb structure composed of a tire tread material and / or a top composed of a tire tread material having a tire tread pattern for added grip and traction.
Description
FIELD OF THE INVENTION[0001]The present disclosure relates to high heel footwear, and more particularly to a top lift assembly of a heel stem having an anchoring mechanism and a cushioning feature.BACKGROUND[0002]Existing designs of the heel tip for a high heel have many drawbacks and flaws, including the materials used, design and engineering of the heel tip, and how it is attached to the heel. Heel tips are used for protection against the severe abrasive pressure on the heel during normal walking. Various types of heel tips have been devised, but at the present time, conventional heel tips consist of a hard polyurethane or plastic / rubber mix molded around a metal nail head with the nail stem protruding beyond the polyurethane material. To securely fasten the heel tip to the heel, the nail stem is driven into a bore extending along the inside of the heel.[0003]A large amount of stress and pressure is concentrated on a heel tip from the impact against the ground, especially when wal...
