A smart shoe has a height-adjustable heel having a plurality of co-axially oriented, concentric cylindrical wall sections of progressively different diameters comprising a skeleton framework. The wall sections are extendable from a collapsible position wherein the wall sections substantially completely overlap in an axial direction to an extended position wherein the walls sections are extended in an axial direction. Heel height is determined by the number of uncollapsed wall sections. A controller element provides incremental heel height adjustments through the sequential collapse of one wall section at a time starting with the uppermost wall section. The smart shoe includes reversibly expandable components for automatically modifying its width, length, and arch support height to provide an optimal fit of both shoes comprising the pair of smart shoes at every selected heel height.

Disclosed is a shoe-lifting device to be worn on a foot or footwear of a person. The shoe-lifting device includes a base platform having at least two indentations on an upper surface of the base platform. The base platform is configured to support the person and make contact with the ground. The shoe-lifting device also includes at least two straps configured to be connected to the base platform and to secure the shoe-lifting device to the foot or the footwear. The shoe-lifting device further includes at least one height-increasing insert having at least two protrusions. The at least two protrusions are positioned corresponding to the at least two indentations and are configured to be coupled with the at least two indentations. The insert is configured to be positioned in and/or on the base platform and to contact the bottom of the foot or the footwear.

A shoe includes a shoe upper that holds a wearer's foot when worn. A shoe sole is connected to the shoe upper and has a collapsible section including a body that at least partially defines a pocket in the collapsible section. An insert is installed in the pocket. The insert has a vertical thickness that expands the collapsible section and increases the vertical thickness of the shoe sole compared to when no insert is installed in the pocket. The shoe may be used for limb length correction.

A spring compression system for shoes that functions much like a car's suspension in absorbing the shock and impact that occurs when shoes contact the ground. Wherein form is the most important element of shoes and function is a distant afterthought, the ergonomically poor design of shoes desperately require the healthier environment for the wearer a spring compression system would offer with the additional ability to be adjusted to suit the weight of the wearer as well as the level of shock absorption desired.

A shoe configured to adjust from a first configuration having a first height to a second configuration having a second height includes a sole. Sole includes a toebox, a shank, and a seat. The shank is rotatably connected to the toebox and the seat. The shoe also includes a heel assembly mounted to the seat. The heel assembly includes a collapsible exterior shell that adjusts the shoe between the first configuration and the second configuration, the first height of the first configuration being greater than the second height of the second configuration.

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.
