  • Patent number: 9185946
    Abstract: Customized, form-fitting athletic articles with a heat moldable material that a wearer may heat to soften after purchase to conform the heat moldable material so the contours of the wearer's body may provide many advantages for consumers, such as increased comfort, performance, or safety. The heat moldable material may be incorporated into the upper of an athletic shoe. The heat moldable material may be sufficiently flexible so as not to impede the necessary movements of a wearer or the athletic shoe while performing activities, such as running, walking, jumping, etc. The heat moldable material may be reusable in that it may be reheated and remolded multiple times so that the article may be re-customized or re-fitted as needed. The article may also include a temperature sensitive indicator that indicates when the heat moldable material has been softened.

  • Publication number: 20110265348
    Abstract: A customizable pointe shoe insert is provided. Such an insert achieves a “perfect fit” that is customized to each dancer's foot by using a moldable material to substantially fill the voids within the box of the shoe, so weight is optimally distributed across a greater percentage of the surfaces of the toes and forefoot when en pointe. Through use of such an insert, painful and damaging pressure points may also be removed. An insert may be constructed from an impression material that when applied, precisely contours itself to the foot and then quickly chemically cures into a rubbery, resilient solid. This highly customized fit greatly improves day-to-day comfort and reduces long-term damage to the foot, while also improving stability, support and alignment inside the shoe.

  • Patent number: 7634861
    Abstract: An article of footwear is constructed to dynamically provide width adjustment by cooperative expansion and contraction of a longitudinal split midsole with an expansion element integrated with an outsole that allows the midsole to expand from a narrow width to a wider width. The upper of the shoe has a corresponding section that can expand to a similar degree as the midsole and outsole to enable the volume of the upper to increase proportionally to the width of the sole.

  • Patent number: 7370440
    Abstract: In the exemplary embodiment of the present invention, an instep strap would be used to increase tension on a cord that would substantially encircle a circumference of an ankle portion of a shoe. In the exemplary embodiment, a first end of the cord would be attached to an instep portion of a first side of a shoe upper; a second end of the cord would be attached to an instep portion of a second side of the shoe; and the cord would pass through at least one channel substantially disposed around the circumference of the ankle portion of the shoe. In an alternative exemplary two-cord embodiment of the present invention, an instep strap would be used to increase tension on two cords. By tightening and fastening the instep strap, both cords would be somewhat distorted and a tension would be created, or increased, thereby causing a snug fit of the shoe.
