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.

A shoe heel (1) which is height adjustable so as to have at least two positions, to which a respective height (h1, h2, h3) of the heel (1) corresponds, at which it can be locked, the heel (1) comprising: a hollow body (101 ) adapted to be fastened to the sole (2) of the shoe, provided with grooves (121a, 121b, 122a, 122b, 123a, 123b) arranged at different heights from one another; a group (102) of components at least partially inserted into the hollow body (101 ), the group (102) of components and the hollow body (101 ) being adapted to mutually slide; said group (102) of components comprising a lever (103); a button (104) connected to the lever (103), adapted to cause a rotation of the lever (103); - at least one locking element (106, 107) connected to the lever (103) so as to switch from a locked position, in which said at least one locking element (106, 107) is inserted into a groove (121a, 121b, 122a, 122b, 123a, 123b) of the hollow body (101 ), whereby the group (102) of components and the hollow body (101 ) are mutually locked in position; to a sliding position, in which the group (102) of components and the hollow body (101 ) can mutually slide; elastic means (108) arranged so as to exert a force which brings said at least one locking element (106, 107) from the sliding position to the locked position.

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.

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.

A convertible high heel and flat shoe, comprising a sole including a heel section; and a high heel piece positionable between a high heel mode where the high heel piece supports the heel section and a flat shoe mode where the high heel piece is received within the sole.

Novel semi-permanent and/or permanent high heel repair device and/or decorative cover slips over the original material on a high heel to either change the decoration, protect the original high heel material from damage, or to cover damage that occurred on the high heel or on the underlying high heel material. The invention comprises a tube of material in a variety of shapes (depending on the shape of the high heel) with one end of the tube closed, or both ends open. If one end is closed, the closed end has a small hole in it allowing for a heel tip dowel to pass through, stopping at the heel tip (neither the dowel nor the heel tip are part of the device), which helps secure the invention to the high heel. The invention may be semi-permanently attached using this method or permanently attached using this method or additional adhesive or another fixative. The shape of the invention can match the profile of the high heel or be a different profile from the high heel. The invention will be created in several sizes, heights, thicknesses and profiles to fit on several different high heels and either mimic the high heel's original shape or may change the original high heel shape.

A heel structure with an adjustable height includes a support rod, adjustment rod, and retractable element. The support rod is penetrated by a through hole. Tracks and engaging grooves are disposed on the wall of the through hole. The engaging grooves are in communication with the tracks and run horizontally. The adjustment rod penetrates the through hole and undergoes displacement. Resilient engaging bumps are disposed above the adjustment rod and thus resiliently pressed within the tracks. The tracks abut against the engaging bumps such that the engaging bumps retract. The retractable element is rotated such that circular pipes of different diameters decreasing downward and stepwise are fitted together so as to be folded and unfolded. A hollow-core mounting region is defined centrally at the circular pipes. A fitting hole is disposed at the lowest circular pipe and fixedly disposed on an outer wall of the bottom of the adjustment rod.
