Examples of the disclosure are directed to a tap apparatus for attachment to a tap shoe. In some examples, the tap apparatus can include an upper tap portion that can be attached to the tap shoe, and a lower tap portion that covers and protects the fasteners used to attach the upper tap portion to the tap shoe. In some examples, the lower tap portion may slide onto the upper tap portion using a dovetail-like attachment mechanism. Screws or locking tabs may then be used to hold the lower tap portion in place. In some examples, the lower tap portion may be affixed to the upper tap portion using a threaded fastener, plug, or floating screw. In some examples, a tab in the upper tap portion can be retained in an aperture in the tap portion, and the lower tap portion can be pivotably engaged with the upper tap portion.

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.
