Abstract: An interchangeable shoe heel for a shoe having a shoe body with a heel part, the heel part having a metal rod extending over at least half the length of the shoe heel, and connected to the heel part, the rod protruding with its free end from the heel part. The shoe heel has a first part having an upper recess into which the rod engages with its free end and/or the heel part. The upper recess has a support surface, e.g., a collar or base wall, on its inner wall, on which the rod or a support area of the heel part is supported in the axial direction of the rod. A heel tip is arranged on the lower end of the first part, and the first part is covered by and connected to an encasing wall, extending from the heel tip up to the shoe body.

Abstract: The modular shoe assembly described herein has removable foot housing straps (a.k.a uppers), and a heel band. This allows a user to customize the shoe in limitless ways, as each of the uppers and heel bands can have any variety of colors, patterns, prints, embossments, or other ornamental decorations such as beads or pearls. When the shoe is a sandal or something, the upper can be removably connected to a toe strap or thong at the front of the shoe assembly and a heel on an underside of the sole. The shoe assembly may also be a ballet shoe, loafer, or similar design, where removably uppers are not needed, and the shoe thus only has a removable heel band.

Abstract: The systems and methods described herein attempt to provide data capture and analysis in a non-intrusive fashion. The captured data can be analyzed for qualitative conclusions regarding an object's actions. For example, a system for analyzing activity of an athlete to permit qualitative assessments of that activity comprises a first processor to receive activity-related data from sensors on the athlete. A first database stores the activity-related data. A second database contains pre-identified motion rules. A second processor compares the received activity-related data to the pre-identified motion rules, wherein the second processor identifies a pre-identified motion from the pre-identified motion rules that corresponds to the received activity-related data. A memory stores the identified pre-selected motion.

Abstract: A massage shoe equipped with germanium includes an outsole and a shoe pad made from high polymers (such as rubber or plastics). The outsole has a recess at the top surface surrounded by a flange to hold the shoe pad. The shoe pad has a plurality of bosses of different shapes formed at the top thereof. Each of the bosses has a plurality of massage bulged spots formed at the top surface. At least one of the bosses (or all) contains germanium which can radiate infrared light to provide massage and healthcare effect to users wearing the shoe.

Abstract: A women's shoe with flexible shank for use with replaceable heels of different height includes a sole with a forward support portion and a raised heel portion and an overlying insole. An elongated flexible spring steel shank is nested within a slot between the insole and sole and at one end anchored thereto. A high heel registers with the heel portion and interlocking fasteners upon the heel and heel portion upon limited rotation of the heel relative to the shoe removably anchors the heel upon the shoe. The heel upon limited angular rotation and disengagement of the fasteners is adapted for removal and replacement by a low heel having similar fasteners. The shank moves within the slot to compensate for the change in height. The interlocking fasteners include opposed interconnected lock segments and anchor flanges secured respectively to the heel and heel portion.

Abstract: A shoe replaceable heel device including a heel base including a replaceable heel mounted on the bottom of the heel portion of the sole of a shoe, a replaceable heel connecting means for removably screwing said replaceable heel to the underside of the heel base and fastening means for securing the heel base to the sole. The connecting means includes a circular base plate secured to the underside of the heel base and a circular replaceable plate secured to the top of said replaceable heel. The base plate has a male threaded perimeter and the replaceable plate has female screw threads adapted to mate with the threaded perimeter of the base plate. The connecting means for women's replaceable high heel is to secure base plate directly to heel portion of shoe sole and apply fastening means described.
