Description
- This application claims the benefit of priority to U.S. Provisional Application No. 61/680,515, filed on Aug. 7, 2012, entitled EXPANDABLE SHOE WITH FLOATING OUTSOLE, the entire subject matter of which is incorporated herein by this reference for all purposes.
- The present invention relates to a shoe that expands and contracts along a lengthwise direction of the shoe,
- The construction techniques and materials utilized in modern footwear and shoes have enabled most shoes to outlive the wearer's individual needs for shoes of that size. Such needs may occur over an extended length of time, such as a child's gradual outgrowth of their current shoes, or on a daily basis, such as the need for a larger size shoe due to swelling of the feet, water retention, gout, arthritis, etc.
- Certain prior art designs of expandable shoes either add significantly to the manufacturing costs of the shoe or adversely affect the aesthetics or comfort of the shoe or even require specific reconfiguration of the shoe to achieve discrete incremental increases in the lengthwise size of the shoe.
- Accordingly, a need exists for a shoe design in which the shoe is expandable and contractible along the lengthwise axis of the shoe to accommodate either temporary or gradual changes in the foot size of the wearer.
- A further need exists for a shoe design in which the shoe is continuously expandable and contractible along the lengthwise axis of the shoe.
- Yet another need exists for a shoe design in which the shoe is expandable and contractible in a manner which does not adversely affect the aesthetics or comfort of the shoe or require specific reconfiguration of the shoe to achieve expansion or contraction of the shoe.
- U.S. Pat. No. 6,374,515 discloses a shoe with an insole configuration which enables expansion of the shoe's upper portions. The floating insole has a section that spans a gap between separate front and heel outsole parts. Although the insole does provide some degree of protection from pebbles rocks or other debris on the walking surface, the intermediate gap portion of the shoe is exposed.
- Accordingly, need exists for expandable shoe that adequately protects the under surface of wearer's foot, while still allowing for expansion of the shoe upper.
- Further need exists for an expendable shoe that provides a protective outsole over the entire length of the shoe while still allowing for expansion of the shoe upper.
- A shoe design is expandable along its lengthwise axis utilizing one or both of a sliding outsole configuration or a sliding insole configuration. In one embodiment, the shoe has a multipart upper and/or multipart outsole interconnected by an expandable section made of a stretchable material which surrounds a pair of insole members arranged in an overlapping manner, but allowed to move freely relative to one another as the expandable section expands or contracts. In another embodiment, the shoe has an outsole slidably received within the heel of the shoe in addition to the expandable section and/or overlapping insole members.
- More specifically, disclosed herein is a shoe design in which a shoe, having an upper portion that is expandable at least along a length of the shoe, further includes a multipart insole slidably disposed within the upper portion of the shoe so as to allow for lengthwise expansion of the insole as the upper portion of the shoe expands. In various embodiments, the upper portion itself may be made of an expandable material or may comprise front and back portions interconnected by an expandable segment. The outsole of the shoe may also have front and back portions or may utilize the sliding outsole design as described herein. In the contemplated embodiments, at least two insole pieces slide relative to each other, with each piece being attached to either a portion of the shoe upper or shoe outsole. In various disclosed embodiments, a front insole portion may be disposed either above or beneath a rear insole portion to allow motion relative thereto as the shoe expands lengthwise.
- According to another aspect of the disclosure, an insole for use in an expandable shoe comprises a front insole portion and a back insole portion disposed adjacent one another but not mechanically coupled so as to allow relative sliding motion therebetween when the portion of the shoe to which the insole portion is attached moves along a lengthwise axis of the shoe,
- Further disclosed herein is a shoe design in which a shoe, having an upper portion that is expandable at least along a length of the shoe, further includes an outsole slidably received within the heel of the shoe so as to allow for lengthwise expansion of the outsole as the upper portion of the shoe expands. In one embodiment, the shoe comprises a heel having a top surface and a breast surface, the heel defining a cavity that is open on one of the breast surface and top of the heel. The outsole extends from a front of the shoe upper to the heel, with a rear portion of the outsole being received within the cavity. An optional shield element, having a front portion connected to the outsole and a rear portion connected to heel, preventing water and dirt from entering the heel cavity. In other embodiments, the sides of the shield are connected to the shoe upper in manner that does not inhibit the longitudinal expansion of the upper. For example, the connection of the sides of the shield to the upper may be accomplished by a cross-stitch or a zig-zag stitch.
- According to another aspect of the disclosure, a shoe comprises an expandable upper having first and second ends, and an outsole having first and second ends, wherein a first end of the outsole is fixed relative to an end of the expandable upper and a second end of the outsole is unattached to the expandable upper and floats relative to the expandable upper in both expanded or contracted states.
- According to yet another aspect of the invention, a shoe comprises an expandable upper, a heel securable to the expandable upper and defining a cavity at least partially extending through the heel, and an out sole having a first end movably disposed within the heel cavity and a second end fixed relative to an end of the expandable upper.
- According to still another aspect of the invention, an expandable shoe comprises a front upper portion, a rear upper portion, a front outsole portion, and a rear outsole portion, an expandable portion between the front upper portion and the rear upper portion and between the front outsole portion and the rear outsole portion, a first insole on the front outsole portion, and a second insole on the first insole and the rear outsole portion, the rear insole being sized substantially the same as a foot contour, wherein the first insole is movable relative to a front portion of the second insole along a lengthwise direction of the expandable shoe. In one embodiment, the first insole is sized substantially the same as the front outsole. The rear outsole portion comprises a heel. The first insole is securely coupled to one or both of the front upper portion and the front outsole portion. A rear portion of the second insole is securely coupled to one or both of the rear upper portion and the rear outsole portion. The first insole frictionally contacts the front portion of the second insole. The expandable portion is made of a stretchable material.
