An interchangeable heel device for a shoe is disclosed. The device has an upper heel block, a detachable heel, and a key. The key is in a top of the detachable heel or in a bottom of the upper heel block and a receiving recess is in the other of the detachable heel or upper heel block. The key is movable within the receiving recess between a released position and an engaged position. In the engaged position, each key first engagement portion is engaged with one of the receiving first engagement portions and each key second engagement portions is engaged with one of the receiving second engagement portions to join the key to the perimeter of the receiving recess and the heel to the sole. In the released position, each key first engagement portion is aligned with one of the receiving non-engagement recesses and the key is removable from the receiving recess.

A shielding cup is provided for use with a self-fusing member or collapsible heat-concentrating accessory. The shielding cup is attached to a shoe heel as a temporary fix for a worn heel tip. The cup can be attached to the heel by a self-fusing member that binds to itself. The cup can also be attached by using a heat source and collapsible heat-concentrating accessory to concentrate heat on the heat-shrink version of the shielding cup. The cup can also be press fit on to the heel tip without the use of a self-fusing member or collapsible heat-concentrating accessory. Embodiments of the cup that can be press fit on to the heel tip include a rigid portion adjacent the base of the cup that engages the heel tip and a flexible portion extending away from the base of the cup. The flexible portion can be achieved by tapering the sidewalls of the cup along a longitudinal axis of the cup. Some embodiments of the cup that can be press fit on to the heel tip include a widened base having an outer periphery that is larger than an inner periphery.

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.

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.
