An article of footwear is disclosed that includes an upper, an outsole, and a midsole. The upper is configured to receive a foot, and the outsole is secured to the upper. The outsole defines a plurality of apertures extending entirely through the outsole. In addition, the outsole has a ground-engaging surface positioned at a first elevation. The midsole is positionable such that a lower surface of the midsole extends into the apertures of the outsole and is exposed by the apertures.

A shoe system including a shoe upper with a bottom side having an aperture extending to a cavity. The shoe system also includes a selectively removable outsole which includes a bottom for contacting the ground, and a top for engaging with the bottom of the shoe upper. The top side of the outsole further includes a projection which is sized and shaped to extend through the aperture and into the cavity when the outsole is in a first orientation, which is misaligned with respect to the shoe upper. The projection is also sized and shaped to fit within the cavity but no longer back through the aperture when the outsole is in a second orientation, which is aligned with respect to the shoe upper. In the second orientation, the projection within said cavity prevents disengagement of the outsole from the shoe upper.

A support interface apparatus removably couplable to a cleated cycling shoe to enable the user to walk on an underlying substrate with minimal slipping on the substrate and/or minimal damage to the underlying substrate by the cleat. The apparatus includes a base pad and a cleat cavity located in the front portion of the base pad. The cleat cavity includes a perimeter, a base, and a cleat-retaining space established by the perimeter and the base. The cleat cavity is arranged for removably retaining the cleat of the cycling shoe therein so that the user may walk on the underlying surface without the heel and the cleat making direct contact with the underlying substrate.

The invention provides a system and apparatus of shoe with interchangeable and detachable attachments such as heels and soles. Specifically, the invention provides a handy and user-friendly solution for changing the interchangeable soles and heels, and that is capable of providing overall good end-user experience of wearing the shoes. The invention achieves the above function objectives by means of longitudinal bars affixed to soles and heels which are configured to be slided and interlocked forming dovetail joint with longitudinal slots beneath the shoe. The shoe has a lock and release latch mechanism which can secure the sole or heel component from sliding out of the dovetail joint.
