A collapsible footwear and a method of altering the configuration thereof into a compact form, configured for transportation, is described; the collapsible footwear includes a top part and collapsible sole including: a top sheet, bottom sheet, lateral support elements, laterally extending channels, top hinge elements, bottom hinge elements and stopper element, reversibly assuming collapsed and erected configurations; the method includes providing a collapsible sole, providing at least one top part, compressing the collapsible sole to assume a collapsed configuration and altering the configuration of the collapsible sole to assume an erected configuration.

The invention relates to an apparatus and methods for putting on and removing a footwear product. The apparatus for putting on and removing a footwear product includes a sole element, a top element, a pedal element, a fixing element, an elasticity element, an interconnection element. In the design of the footwear product, the sole element is connected with the top element and the pedal element, the top element and the pedal element are connected with the interconnection element, the elasticity element is connected with the top element and/or the pedal element, the fixing element is configured to engage with the matching part and fix the pedal element in the pressed position. If the sole element is curved, it is configured to fix the foot in the footwear product in the “closed” state of the footwear product, the interconnection element is connected with the top element, the pedal element, and the sole element, and the elasticity element is connected with the top element and/or the pedal element and/or the sole element. The sole element serves as a foot support, the top element is configured to cover and fix the foot in the footwear product in the “closed” state of the footwear product, the pedal element is configured to receive energy from the pressure of the foot and bring the footwear product to the “closed” state, the fixing element is configured to fix the footwear product in the “closed” state, the elasticity element exhibiting potential energy is configured to bring the footwear product to the “opened” state, the interconnection element is configured to transfer motion from one element to another. The technical result is a reduction in the time and effort consumed for putting on and removing the footwear product.

Footwear with a heel portion having a clasp member with resilient arms having locking tabs that engage with locking slots in a receptacle member in a main portion, when the heel portion abuts against the main portion. The locking tabs disengage from the locking slots when simultaneously squeezed together by a tool that extends through locking tab access holes on both sides of the main portion. The locking tab access holes are too small for a child's fingers to enter. The clasp member and receptacle member can be in either the heel portion or the main portion.

Sole structures, foot support systems, articles of footwear, and/or other foot-receiving devices include: (a) a first footwear component having a ground-facing surface, wherein a forefoot portion of the ground-facing surface includes arched medial and lateral surfaces and (b) a second footwear component having an upper-facing surface, wherein a forefoot portion of the upper-facing surface includes arched medial and lateral surfaces that face (and optionally contact) the respective arched medial and lateral surfaces of the first footwear component. The first and second footwear components are movably engaged together such that: (a) the arched medial surface of the first footwear component moves with respect to and along the arched medial surface of the second footwear component and (b) the arched lateral surface of the first footwear component moves with respect to and along the arched lateral surface of the second footwear component.

A modular heel footwear system is provided which may comprise an outsole portion of a footwear article having a first interlocking groove which may comprise a plurality of cavities disposed therein. The plurality of cavities may be disposed symmetrically along the length of the first interlocking groove relative one another. Further, the system may comprise a modular heel device which may comprise a second interlocking groove, having a plurality of locking tabs protruding therefrom that may quantitatively correspond to the plurality of cavities. The plurality of locking tabs may be disposed symmetrically along the length of the second interlocking groove relative one another. Additionally, the first interlocking groove may structurally correspond to the second interlocking groove.

An article of footwear, including one or more interchangeable upper portions, the upper portion including loops on a bottom portion of the upper portion, a sole, the sole having engagement points around a perimeter of the sole, wherein the engagement points in the sole allow the loops to be inserted and/or removed; at least two spring lock systems, the spring lock systems located in the perimeter of the sole, wherein the spring lock systems include a spring, a flexible shaft, a lock and a spring plate, the lock and the spring plate being located in the engagement points, wherein the loops of the one or more upper portions to the sole engage with the lock and spring plate to secure and/or release the loops in position; and two or more sets of buttons on the sole to release or engage the spring lock system.

The present disclosure describes a shoe that may be transformed from a high heel shoe to a low heel shoe. The shoe may include three parts: a removable stelo, a removable high heel attachment, and the corresponding attachment systems integrated into the base shoe sole. The removable high heel attachment may be a standard heel of any design, width and height that has a locking system comprising a threaded post located at the heel base. When the stelo and heel attachment are attached, the shoe may be a high heel shoe. When they are removed, the shoe may be a low heel shoe, or flat shoe.

The invention relates to a set comprising a shoe (1) with a shoe sole (3), which has a support layer (31) and a plurality of support elements (4), wherein the support layer (31) comprises a plurality of cavities (310) having identical, constant cavity cross-sectional areas. At least one end face of each cavity (310) is recessed, whereby a structure of cavities (310) open on at least one side is created in the support layer (31). The support elements (4) are designed as rods with identical, constant cross-sectional areas and can be inserted into and removed from the cavities (310) in a form-fitting manner, wherein the support elements (4) are present in different strengths, such that the damping of the shoe sole (3) can be changed by the choice of the inserted support elements (4).

A footwear construction capable of incorporating one to three or more platform layers, or no platform layers at all. The invention comprises a kit including a sneaker member, optionally includable in the final construction first second and third platform members, guide members, optionally in sets of three, suitable for inclusion in a constructed footwear item with one, two or three platform members, and a tread its sole member, optionally replaceable by other types of soles.

The present disclosure relates to a custom article of footwear, a method of making the same, and a method of conducting retail and Internet business. In particular, the components of the custom article of footwear can be selected from a range of alternative options, and the selected components can be easily removed, replaced, and recycled.
