Provided is a walkable shoe having a glass-like appearance. The shoe has a heel portion, a sole portion provided on the heel portion, and an upper portion provided on the sole portion; wherein the heel portion and the sole portion are made almost entirely of an organic glass, and the upper portion is made almost entirely of an organic glass.

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 heel attachment device for the heel of a shoe having an elevated heel is formed from a piece of solid elastic material having a top surface, a substantially horizontal bottom surface, and a substantially vertical opening extending from the top surface part way to the bottom surface so that the bottom surface is closed, producing a bottom layer having an inner bottom surface and an outer ground contacting surface. The inner bottom surface includes features that protect the shoe and the invention. The outer ground contacting surface includes features that reduce slippage against the ground and sound produced by walking, and the bottom layer can include features that cushion walking and/or produce light or color. The outer surface of the invention may have ornamental characteristics.

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.

The invention relates to a sole component for a shoe suitable for use with different heels. The sole component comprises a front, a middle and a rear sole portion and comprises a mechanism for adjusting the sole curvature in a transition region between the front and the middle sole portion. The mechanism comprises a rotatable supporting element which is provided in such a way that it may have a first angular position which causes a first sole curvature in the transition region and a second angular position which causes a second sole curvature in the transition region, wherein the first sole curvature is different from the second sole curvature.
