Disclosed is a multi-level footwear sole including a lower section having a top side and a bottom side for contacting the ground; an upper section having a top side and a bottom side for interfacing with one or more components of a two-wheel vehicle; and one or more interconnection elements/sections for orienting and retaining the upper level in relation to the lower level, such that the upper and lower levels are positioned at substantially parallel planes, at least partially overlap, wherein the bottom side of the upper section faces the top side of the bottom section, forming therebetween one or more hollow chambers to accommodate/house the interfaced components of the two-wheel vehicle.

An exercise apparatus includes a pair of step-up apparatuses wearable on feet of a user. Each step-up apparatus is configurable between an expanded configuration and a compressed configuration to simulate a selected motion when the user wearing the pair of step-up apparatuses travels by foot. One of the step-up apparatuses moves towards the expanded configuration while the other step-up apparatus moves towards the compressed configuration.

A retractable high heel shoe. The retractable high heel shoe includes a shoe having an upper portion extending perpendicularly upwards from a sole defining an interior volume that can receive a foot therein. A heel having a lower side is affixed to the sole at a rear side of the shoe. The heel includes a plurality of sections that can telescopically move between an extended position and a retracted position.

The present invention relates to visco-elastic inserts, in particular to shoe inserts, and in particular to heel supports having a main body with regions of dissimilar hardness.

Methods for providing footwear configured to treat leg length discrepancy include manufacturing a plurality of footwear members. Each footwear member has a sole thickness, with sole thicknesses of the plurality of footwear members spanning a predetermined range of thicknesses. A corrective pair of footwear may be formed by selecting a left member having a first sole thickness and a right member having a second sole thickness, wherein the difference between the first and second sole thicknesses corresponds to an amount of leg length discrepancy to be corrected.

The invention relates to a sole component for a shoe suitable for use with different heels. The sole component comprises a front, a middle and a rear sole portion and comprises a mechanism for adjusting the sole curvature in a transition region between the front and the middle sole portion. The mechanism comprises a rotatable supporting element which is provided in such a way that it may have a first angular position which causes a first sole curvature in the transition region and a second angular position which causes a second sole curvature in the transition region, wherein the first sole curvature is different from the second sole curvature.

A shoe capable of adjusting heel height includes a front bracket, a rear bracket, a telescopic linkage rack, a telescopic support member, a linking member and a locking mechanism. The rear bracket is rotatably connected to the front bracket. The telescopic linkage rack is pivotally connected to the rear bracket, and can be telescoped with the movement of the rear bracket. The telescopic support member is fixedly connected to the telescopic linkage rack, and can be simultaneously telescoped in the same direction and in the same proportion with the telescoping degree of the telescopic linkage rack. The linked member is pivotally connected to the front bracket and the telescopic support member, and arranged spaced to the rear bracket, and the linked member is spaced to the rear bracket. The locking mechanism can removably fix the telescopic support member for limiting the telescopic support member.

The inventor has realized that there is a need for adaptive footwear that can respond to variations in surfaces on which persons travel or exercise. The adaptation can extend to self-leveling functions to resolve surface asymmetry. According to some aspects, footwear, and for example, athletic shoes, can be improved to adjust the height of a person's foot based on dynamic adjustments made in the sole of the footwear. According to some aspects, differences in striking height (e.g., a distance between the user's foot and the ground) between shoes can induce asymmetry in leg length resulting in medical issues. An athletic shoe can provide self-leveling functions to automatically adjusts the shoe to even out an asymmetry that is detected by embedded sensors.
