A device for attaching removable interchangeable heels for shoes. A system for locking and unlocking interchangeable heels in order to change heels as desired, while keeping the same pair of shoes, includes a base with tenon, called the housing, wherein a flat locking spring is located, and a mortise part wherein a second flat spring is inserted. The mortise and tenon assembly is locked when the two flat springs, having complementary shapes, come into contact and immobilize one another. The user can act on the tab of the locking flat spring in order to rotate it and unlock the heel. The flat spring automatically returns to its initial position due to its elasticity, when the user releases it.

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.

A retrofit shoe heel system for stiletto-heeled shoes has a heel outsole piece, a heel midsection piece, and a heel top piece. The heel outsole piece has a column extending therefrom with an open-end, hollow shaft running longitudinally therethrough which is sized and shaped to receive the stiletto heel of a shoe, and a ground contact surface area extending outwardly about the column which increases the shoe's heel ground contact area. The heel midsection piece has an outer contour substantially matching an outer contour of the outsole piece, and an aperture therethrough which is sized and shaped to surround the column of the outsole piece. The heel top piece has a skirt portion with an outer contour substantially matching an outer contour of the outsole piece, and an aperture therethrough which is sized and shaped to surround the column when stacked on top of the outsole piece.

A heel construction for a high heeled shoe 11 includes a sole plate 10 and a heel pin 12 projecting downwardly from the sole plate. A detachable heel component 16 is fitted to the heel pin and a releasable locking arrangement serves to secure the heel component to the heel pin. The locking arrangement may comprise a threaded region 20 on the pin and engageable by a nut 23 carried in the heel component 16 or may comprise snap fittings 52,57 on the heel pin and within the heel component, to secure the heel component to the heel pin.
