Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to U.S. provisional patent application Ser. No. 62/086,118 filed Dec. 1, 2014, which is incorporated herein in its entirety by this reference thereto.

FIELD

The disclosed embodiments concern high heel shoes with supportive cushioning integrated into the footwear.

BACKGROUND

High heel shoes, also called high-heeled footwear or high heels, are footwear that raises the heel of the wearer's foot significantly higher than the toes. High heels are ubiquitous in everyday life and used whether as part of business dress or as a fashion statement. However, because high heels increase the angle of the heel to the foot much higher than is natural, wearers of heels suffer from unnatural walking strides, stresses to the musculoskeletal system, pain, blisters, and other related conditions.
A cottage industry exists to ease the wearing of heels, such as the insertable orthotics. These orthotics can be slips that fit into the entire portion of the shoe, or can be inserted into certain areas to provide support in particular areas. The orthotics cushion the stress areas and reduce pain and the likelihood of blisters.
The orthotics are often formed of fabrics, foam, gel or another polymer. These orthotics provide insufficient weight support and slip around the shoe.
Fabric and foam cushioning are easy and cheap to manufacture and use, but provide suboptimal support for the user because they provide little shock support. These variety of orthotics also degrade easily, thereby requiring users to regularly purchase replacements. Additionally, such orthotics generally provide insufficient traction for the user and allow for slippage.
Gel orthotics do not provide sufficient shock absorption because of the nature of the material and the form and shape in which they are currently produced; gel orthotics are usually flat or otherwise formed such that the gel does not bounce back well. Both gel and foam orthotics also dampen the energy the user puts into his or her stride, thereby requiring more energy from the wearer to walk and causing the wearer's muscles to tire more readily. These orthotics also easily slip around inside the shoe and against the user's foot.
Polymer orthotics also suffer from problems similar to those described above.
Moreover, because orthotic inserts generally mold to the user's foot, they provide limited support that degrades over time because the material does not bounce back against pressure points. Additionally, because most orthotics are not attached to the shoe, or are attached to the shoe by means of a weak adhesive, orthotics readily slip around the shoe while the wearer is using them. Though a variety of orthotics uses a small loop attached to the user's toes to stay secure, these are problematic because they are uncomfortable to wear and are not securely attached. Orthotics that are attached to the shoe by means of an adhesive are susceptible to the problem that a strong or long-lasting adhesive damages the shoe.

Summary

The disclosed embodiments concern high heel shoes, especially platform shoes, with incorporated supportive cushioning.

DETAILED DESCRIPTION OF THE DRAWINGS

Various example embodiments will now be described. The following description provides certain specific details for a thorough understanding and enabling description of these examples. One skilled in the relevant technology will understand, however, that some of the disclosed embodiments may be practiced without many of these details.
Likewise, one skilled in the relevant technology will also understand that some of the embodiments may include many other obvious features not described in detail herein. Additionally, some well-known structures or functions may not be shown or described in detail below, to avoid unnecessarily obscuring the relevant descriptions of the various examples.
The terminology used below is to be interpreted in its broadest reasonable manner, even though it is being used in conjunction with a detailed description of certain specific examples of the embodiments. Indeed, certain terms may even be emphasized below; however, any terminology intended to be interpreted in any restricted manner will be overly and specifically defined as such in this Detailed Description section.

Cushioning Material

The cushioning can be composed of various polymers, including Styrene Ethylene Butylene Styrene (“SEBS”), which is a form of thermoplastic elastomer (TPE) with styrene added. SEBS is safe and non-toxic, and has been used as a PVC substitute. SEBS has been used for toys, sports mouth guards, teethers, and handlebar grips. SEBS has a chemical resistance similar to natural rubber. A benefit of SEBS is that it provides superior weight resistance and resiliency to being deformed, particularly over existing materials used for cushioning such as foam. Additionally, SEBS provides traction that can keep a user's foot in place, which prevents slipping, crushing of the user's foot, and blisters. The traction that SEBS provides is superior to those of current orthotics. One brand name of SEBS is Kraton. Another polymer includes rubber. Other polymers include Polyurethane (“PU”), Silicone, and Ethylene Vinyl Acetate (“EVA”).

Manner of Incorporating Cushioning

There are numerous ways of incorporating the cushioning technology. In some embodiments, the cushioning can be manufactured as part of the high heel shoe's body. In some embodiments, the cushioning can also be manufactured separately from the high heel shoe's body, but fixedly attached onto the shoe by methods including an adhesive, sewing, or binding of the materials including by chemical reaction or the application of temperature. In some embodiments, if the cushioning is fixedly attached onto the high heel shoe, the body of the shoe has recesses into which the cushioning is placed. Recesses facilitate the placement, security, and the visibility or invisibility of the cushioning. Those skilled in the art can appreciate that one cushioning can be fixedly attached within a recess and positioned in any of the locations described below, while other cushioning can be fixedly attached to one or more of the interior lining, the counter, the insole, or the outsole, and positioned in any of the locations described below.
The cushioning can be fixedly attached on top of the inner surface of the high heel shoe such that they are visible to the user. The cushioning can also be fixedly attached below the inner surface of the high heel shoe such that they are not visible to the user.

Embodiments of Cushioning

The disclosures provide various embodiments for the cushioning. The cushioning can be located at certain portions of the high heel shoes, as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5, which disclose five general locations for various embodiments. However, these locations are by no means limited to the disclosed locations: depending on the style of the shoe, the user's personal preferences, and/or other factors, the cushioning can be placed at other areas of the shoe. FIG. 1, FIG. 2, FIG. 3, FIG. 4, and FIG. 5 merely reflect locational possibilities incorporated by some embodiments.
