Heel stabilizer

Abstract

The present invention relates to heel stabilizing technology that can be used on many kinds of footwear. This heel stabilizing technology can be incorporated during manufacture of the footwear. This heel stabilizing technology can also be manufactured as a separate component, and then added to many kinds of footwear. The heel stabilizer of the present invention increases the stability of the wearer when walking by minimizing the side-to-side teetering a person experiences when wearing flat heels to any height heel shoe, sneakers, boot, overshoe, galoshes or any combination thereof. Implementation of the heel stabilizing technology results in the heel of the footwear being set to a raised position and then flexed downward at heel strike. The resulting vertical stretch at the heel helps lessen side-to-side teetering of the wearer and thereby increases stability. The disclosed heel stabilizer includes at least one anchoring means, at least one heel lift means, a stretch segment, and a sole. An alternative embodiment includes an upper that conceals the structural features of the overshoe; a sole; a stay to center and stabilize the foot atop the shoe; and a well in the sole's heel to receive the high heel and the bottom of the stay component or, in an alternative embodiment, a hole in the sole so that the high heel and the bottom of the stay component penetrates the hole to form a watertight joint, the protruding heel cup then forms the visible sole of the overshoe.

Gone are the days when a raincoat, umbrella and rain boots are nothing more than a utilitarian way to keep dry. The contemporary equivalent of the British-inspired Wellington boot hit the U.S. market in Fall 2000. These “pattern wellies” or printed novelty rain boots were sellouts with their floral print d...

AI Technical Summary

Benefits of technology

[0026]The present invention meets these needs; by utilizing heel stabilizing technology. Several varying embodiments are disclosed herein. In one exemplary embodiment, relatively stiff, flexing elements are used to both support the ankle and align it atop the heel of the shoe. These stays resist lateral ankle flex and heel toppling by translating any out-of-column lateral movement into tension and compression forces acting on the two stays. The stays are designed to resist this tension and compression loading, resulting in significantly greater stability and wearer confidence. In essence, the heel of the shoe becomes an axial (straight line) extension of the wearer's lower leg. The outer sole of this “stay” embodiment can be either flexible or non-flexible.

Problems solved by technology

However, when women dress in business attire or evening wear, accessorized with high heel shoes averaging well in excess of 1½″, the need for protective footwear for rain which provides both aesthetic satisfaction and physical functionality has yet to be adequately addressed.

In the past, overshoes have been regarded as a clumsy, low cost contrivance with little or no structure.

Further, falls result in enormous economic and personal losses.

Often a fall for an older adult can result in a hip fracture or other serious injury, even death.

In addition, there are many whose mobility is threatened due either to advanced age, neurodegenerative disorder, or other disorder that effects coordination and / or balance.

Some may refuse to use walking aids such as a cane or a walker because the aid is seen as unsightly.

However, the overshoe of the '930 patent has a multitude of cumbersome fasteners, does not have a means for fastening the overshoe to the wearer's ankle or calf, and does not prevent or minimize teetering in high heel shoes.

U.S. Pat. No. 2,068,238 (the '238 patent) shows an overshoe that is waterproof, but that does not have the capability of protecting a shoe with a high heel.

However, the overshoe of the '422patent does not have a slip-resistant sole, is devoid of any type of fastener, and does not minimize teetering in high heel shoes.

In addition, the disclosure of the '422 patent does not contemplate the flexibility / rigidity needs of the sole to provide shoe stability.

However, the overshoe of the '527 patent has a fastener only at the ankle of the boot which would not secure a high heel shoe inside the boot, and the overshoe does not have a means of minimizing teetering in high heel shoes.

However, it would be very difficult to insert a high heel shoe into the opening of the overshoe of the '336 patent and down the body of the boot.

Although the overshoe cover of the '336 patent can accommodate shoes with heels of unspecified height, has a slip-resistant sole and ankle fastener, it does not have a means of minimizing teetering in high heel shoes.

Further, the boot of the '336 patent is not disposable, the elastic band that gathers the boot material onto the arch of the boot could be hazardous if bulky gatherings get caught on an uneven slippery surface.

Additionally, the separate heel and sole portions do not provide the same amount of security as would a heel and sole constructed in the same piece.

Lastly, a tall, narrow heel such as a spike heel would not be strong enough to hold down the heel portion of the boot and can cause a tripping hazard.

DE 3,606,837 (the '837 patent) show an overshoe that has the advantage of being extendible in bootleg coverage, but it is not disposable or compact for carrying in a purse.

Furthermore, the soles of these overshoes, although they have tread patterns, do not provide for increased ground contact effectively making the wearer walk on snow and ice in high heels with treads.

The overshoes of the '556 patent and the '997 patent have extendible heels, are devoid of any type of fastener, and do not minimize teetering in high heel shoes.

The overshoe of the '240 patent is for indoor use, does not have a slip-resistant sole, does not accommodate high heel shoes, and does not have a means of creating tension at the heel to provide the wearer of high heel shoes with greater stability.

The '240 patent has gripping action on the interior surface of the sole of the overshoe, however, it does not provide for securing the overshoe around a front section of the shoe and on the leg so that the wearer's shoe is not positively engaged by any portion of the overshoe.

Although the overshoe of the '258 patent can accommodate high heel shoes and has a slip-resistant sole, the overshoe does not have a fastener at the opening of the leg shaft and does not have a means of providing tension at the heel.
