A variety of insert pads are known for use with shoes. Many of the known insert pads are used underneath a wearer's foot for absorbing shock or odors.
Typically, an insert pad is placed along a top surface of a sole of a shoe. This allows for a wearer to comfortably place his/her foot over the insert pad.
While known insert pads resolve shock and odor problems, they do not necessarily solve other shoe related problems such as irritation and chafing to a wearer's foot (particularly the heel of the foot). There are certain types of shoes that tend to cause this irritation and chafing such as dress shoes, athletic shoes, and high heeled shoes. For example, a high-heeled shoe tends to cause irritation to the wearer's foot due to a heel of the shoe digging in and rubbing against the wearer's heel.
A known solution to these irritation and chafing problems is a heel pad. The heel pad is positioned within a heel section of a shoe. In particular, the heel pad is typically a narrow-shaped pad that is positioned along an inner surface of the heel counter of the shoe. The heel pad provides a comfortable fit between a wearer's heel and the shoe thus limiting friction between the wearer's heel and the shoe. This can result in less irritation and chafing on the wearer's heel (thus eliminating the formation of blisters and calluses).
In one example, the heel pad includes a gel substance for comfortably fitting around a wearer's heel. The gel heel pad typically includes an adhesive strip for anchoring the gel heel pad along the inner surface of the heel counter of the shoe.
Another example heel pad includes a urethane material (e.g., Poron® urethane macroporous material available from Rogers Corporation of Rogers, Conn.) for providing a comfortable fit around the wearer's heel. Similar to the gel heel pad, this urethane heel pad includes an adhesive strip for anchoring the urethane heel pad to the inner surface of the heel counter of the shoe.
The known heel pads experience some shortcomings. For example, the known heel pads do not stay firmly in the heel counters of shoes. In particular, the adhesive strip of each known heel pad does not provide adequate adhesion with respect to anchoring the heel pads in the shoes. This is the result of the adhesive strips losing their adhesion properties over time and in some cases shortly after first use. Thus, the known heel pads tend to shift position during use or the heel pads detach completely from the heel counters of shoes. In addition, due to their typically narrow shape, known heel pads do not provide adequate amount of coverage to protect the entire heel of a wearer's foot. Also, the narrow shape of known heel pads translates into less cushioning material being incorporated within the heel pads.
The present invention is directed toward further solutions to address these needs, in addition to having other desirable characteristics. Specifically, the present invention heel pad includes a malleable member that allows the heel pad to adequately maintain its position within a heel section of a shoe. In particular, the malleable member functions to anchor the heel pad directly to the shoe such that the heel pad securely maintains its position in the shoe. In one example, the present invention heel pad uses the malleable member to affix itself to an outer surface of the heel section of the shoe for fastening the heel pad in place. Furthermore, the present invention heel pad is configured to provide adequate coverage for protecting the entire heel area of a wearer's foot.
In general, according to one aspect, the invention features a heel pad for placement within a shoe. The heel pad includes a pliable body, a filler element contained within the pliable body, and a malleable member fastened within the pliable body and extending along at least part of a length of the pliable body.
The malleable member is typically fastened to the pliable body with stitching. In one example, the malleable member includes a metal material. In another example, the malleable member includes metal material inserted within a fabric covering.
The pliable body has a shape configured to fit the hack of a wearer's heel. In one example, the pliable body is constructed from a fabric sheet.
The filler element typically includes a material having soft, flexible, and moldable properties. The filler element can include a polyester pile, beads, foam, multiple sheets of polyester, microfiber, or gel.
In one embodiment, a shoe side of the pliable body is mounted to an inner surface of a heel section of the shoe such that the heel pad is integrated with the heel section of the shoe. In another embodiment, a shoe side of the pliable body is releasable attached to an inner surface of a heel section of the shoe using a fastener such that the heel pad is attached and detached from the heel section of the shoe.
In general, according to another aspect, the invention features an article of footwear that includes a shoe having an insole coupled to a heel section. The article of footwear includes a heel pad positioned in the heel section of the shoe. The heel pad has a pliable body, a filler element contained within the pliable body, and a malleable member fastened within the pliable body and extending along at least part of a length of the pliable body. The malleable member is bent to fold a longitudinal end of the pliable body along an upper edge of the heel section of the shoe and affix the end of the pliable body to an outer surface of the heel section of the shoe.
In one embodiment, the article of footwear includes an extender heel pad. The extender heel pad can include a pliable body having a filler element therein. In one example, the pliable body of the extender heel pad has a generally hemispherical shape. The extender heel pad is positioned along part of a foot side of the heel pad.
In one embodiment, the extender heel pad is mounted to part of the foot side of the heel pad and a shoe side of the heel pad is mounted to an inner surface of the heel section of the shoe such that the heel pad and extender heel pad are integrated with the heel section of the shoe. In another embodiment, the extender heel pad is mounted to part of the foot side of the heel pad and a shoe side of the heel pad is mounted to an inner surface of the heel section of the shoe such that the extender heel pad is attached and detached from the heel pad and the heel pad is attached and detached from the inner surface of the heel section of the shoe.
In general, according to another aspect, the invention features a method of using a heel pad for a shoe. The method includes providing the heel pad having a pliable body, a filler element contained within the pliable body, and a malleable member fastened within the pliable body and extending along at least part of a length of the pliable body. The heel pad is positioned along an inner surface of a heel section of the shoe. A longitudinal end of the heel pad is folded along an upper edge of the heel section of the shoe. The folded longitudinal end of the heel pad is affixed to an outer surface of the heel section of the shoe.

For example, the heel pad 10 has a relatively long and narrow shape for the high heeled shoe whereas the heel pad 10 has a relatively short and wide shape to accommodate the low heeled shoe. In examples, the heel pad 10 has a total length (from the first end 18 to the second end 20 and measured at max length of shape) between about 9 cm and about 12 cm. The heel pad 10 has a total width (from a first side 15 to a second side 17 and measured at max width of shape) between about 6 cm and about 10 cm that extends in parallel with an A-A axis. The heel pad 10 can be designed with other measurements as appreciated by one of skill n the art in order to accommodate other shoe types,
The heel pad 10 includes a foot side 14 for receiving the heel of a wearer's foot. The heel pad 10 includes a shoe side 16 for placement against an inside surface of a shoe.
The heel pad 10 includes a pliable body 12 forming a shape of the heel pad 10. The pliable body 12 is shaped to fit the back of a wearer's heel. In particular, the pliable body 12 tapers at the first end 18 to fit the back of the wearer's heel. The pliable body 12 has a generally ovoid shape. In other examples, the pliable body 12 has a triangular shape, polygonal shape, or other shape as appreciated by one of skill in the art.
The pliable body 12 can be constructed from a variety of materials. For example, the pliable body 12 can be constructed from one or more layers of cotton, soft leather, suede, micro suede, neoprene, polyester, or other materials as appreciated by one of skill in the art. The materials can be white in color as illustrated. In one embodiment, materials may be selected such that the color of the pliable body 12 matches and blends in with the color of the shoe. In still another embodiment, materials may be selected to produce a pattern and/or an image on the pliable body 12. Materials may be selected to produce other colors and/or designs for the pliable body 12 as appreciated by one of skill in the art.
As illustrated in the cross-sections, the pliable body 12 is constructed from two fabric layers 12A, 12B. Each fabric layer 12A/12B is folded on two opposing sides (first side 15 and second side 17). As shown, the upper fabric layer 12A is folded over itself at the first side 15 and folded over itself at the second side 17. Similarly, the lower fabric layer 12B is folded over itself at the first side 15 and folded over itself at the second side 17. The fabric layers 12A, 12B are stitched together at these folded sides using body stitching 23 (e.g., fabric stitching). In particular, the folded sides of the upper fabric layer 12A are stitched directly to the folded sides of the lower fabric layer 12B forming a seam along the body stitching 23. The upper fabric layer 12A is the foot side 14 of the pliable body 12 and the lower fabric layer 12B is the shoe side 16 of the pliable body 12.
In another example, the pliably, body 12 can be constructed from a single fabric sheet.
The heel pad 10 includes a filler element 22 contained within the pliable body 12 (i.e., between the upper fabric layer 12A and the lower fabric layer 12B). The filler element 22 typically includes a material that generally has soft, flexible, and moldable properties. For example, the filler element 22 can include a polyester pile, beads, than), multiple sheets of polyester, microfiber, gel, foam, feathers, silk, linen, rubber, synthetic plastic, or other materials as appreciated by one of skill in the art.
The heel pad 10 includes a malleable member 24. The malleable member 24 is fastened within the pliable body 12 and extends along at least part of the length of the pliable body 12 as well as at least part of the width of the pliable body 12. In
In
The malleable member 24 is constructed of a material having “malleable” properties. “Malleable” properties include the ability to hammer or press the material permanently out of shape without breaking or cracking the material. The “malleable” properties typically relate to metals that can be permanently bent and twisted into a variety of shapes without breaking. Examples of “malleable” metals can include gold, silver, aluminum, copper, tin, lead, zinc, iron, and other related alloys. A material having “malleable” properties is able to be bent into one shape such that the material maintains this shape until a new force is applied to bend the material into a different shape. Thus, for example, the “malleable” material can be bent permanently into a first shape and then bent permanently into a second shape different from the first shape. The term “malleable” and particularly the terms “malleable member” are to be interpreted throughout the specification based on this definition of “malleable” properties.
