Benefits of technology
[0007]Aspects of the present disclosure solve or overcome at least the above-stated problems and disadvantages. Currently, there is no commercially available heel tip that does not wear out within a few weeks of use. A wearer must or ought to replace the heel tips, on average, every 30 days if that heel tip can even stay attached to the heel that long. An objective of aspects of the present disclosure is to provide a stronger heel tip that can take years of use and abuse before it starts to deteriorate, cannot get pulled out of the heel when worn and used and will help to absorb the harmful shock waves that are sent throughout the entire body with every step.
[0008]The heel tip is made of longer-wearing, resilient materials. One of these materials protects the body from the harmful shockwaves that are caused by every step, jump or stride that the high-heel wearer takes. It has been demonstrated in several studies that the rubber material of this invention stops the harmful shock waves that accumulate over time as damage to the body from our feet to the base of our skull from the repeated exposure the shock waves caused by daily activity.
[0009]Conventional heel tips are made of solid polyurethane, which does not deter the damage from the exposure of the shock waves that can cause numerous chronic injuries. By contrast, according to the present disclosure, some aspects provide a micro honeycomb internal structure in the heel tip to decrease the shock waves the body is absorbing as the high-heel wearer walks, runs or jumps. The micro honeycomb significantly decreases both 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.
[0010]Furthermore, conventional heel tips have a nail or a steel pin that protrudes from the polyurethane material and is hammered or driven into the bore of the heel to hold the heel tip in place against the heel. By contrast, aspects of the present disclosure provide various combinations of anti-rotation, securing, and alignment promoting features to prevent rotation or slippage of the heel tip, secure the heel tip to the heel in a fixed, unmovable manner, and align the heel tip to the heel. According to some aspects of the present disclosure, a threaded insert or expansion anchor can be set in the heel and the heel tip, which can include a square or propeller head screw, with the micro honeycomb structure, is then rotated until the threaded insert locks the screw into place or the expansion anchor opens, locking the screw and heel tip securely into the heel. Optionally, the heel tip can be removed easily, by counter-rotating it, for example, to replace it with a new one or swap it entirely out for a different style.

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...

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...
