A shoe including an upper comprising an outersole, a toe portion, and a rigid plate; and a heel comprising a threaded shaft upwardly extending therefrom, wherein the rigid plate comprises a threaded barrel comprising a lower open end and an upper closed end opposite therefrom, and wherein the heel is removably attached to the upper based on the threaded shaft threading into the threaded barrel from the lower open end to the upper closed end, and wherein the rigid plate extends over the heel when the heel is removably attached to the upper, and wherein the rigid plate extends past the heel towards the toe portion along the outersole.

A convertible shoe may include a sole and a plurality of interchangeable heel portions, each selectively attachable to the sole. The heel portions may each include a mounting surface configured to interface with a heel receiver of the sole. The heel receiver may include a fixed hook and a movable hook, with the movable hook being operable by an actuator coupled to a bottom surface of the sole. In some examples, an upper is secured to the sole of the shoe by one or more clamping plates. In some examples, the sole of the shoe is configured to be biased into a default bend corresponding to a high-heeled state even when a low heel is attached to the heel receiver.

A sole construction (10) for use in a high heel shoe (60) comprises at least a first skeleton sole (11) formed from a composite material such as a carbon fibre material. The skeleton sole (11) has lasting allowances (15) defined around the perimeter thereof and adapted to receive the edges of a shoe upper (61) when incorporated in a high heel shoe (60). The skeleton sole (11) is further shaped so as to define one or more recesses (16) generally centrally therein. When incorporated into a high heel shoe (60), the enhanced strength, rigidity and flexibility of the sole construction (10) allow for the use of a range of interchangeable heel constructions (30,40,50) having different heel heights.

Heeled footwear such as a shoe or boot including a sole assembly and a heel part may be provided. In one implementation, the heel part may include an insert formed in a first material. The insert may include a core body delimited by an upper surface, a lower bottom surface, and an outer surface connecting the upper and lower surfaces. At least a part of the outer surface may be encased in a second material different from the first material. The outer material may form an outer contour layer of the heel part, and the sole assembly may include an outsole formed in the second material, the second material being softer than the first material. The outsole and the outer contour layer may be designed to be formed in one piece providing an outer sole unit being one component.

A high heel footwear including a heel tip assembly and a heel assembly. The heel tip assembly includes a top lift abutting against the heel, a rigid shaft member having a threaded portion, and a first wedge-lock feature configured to prevent the top lift from rotating. The heel assembly includes a threaded insert, a spring, a hollow insert, and a second wedge-lock feature. The threaded insert is received inside an opening formed in the heel to receive the threaded portion of the rigid shaft member. The spring is also received inside the opening and abuts against the threaded insert. The hollow insert abuts against the spring. The rigid shaft member passes through the threaded insert, the spring, and the hollow insert. The second wedge-lock feature locks with the first wedge-lock feature to retain the top lift on the end of the heel.
