The invention is that of a removable shoe sole and a cycling shoe comprising said removable shoe sole, wherein the removable shoe sole may be affixed to the bottom of the cycling shoe to enable the wearer to gain traction on surfaces such as muddy ground surfaces. The removable shoe sole may be unitary or modular in design and comprises traction means such as anterior, medial and posterior traction means for enabling a cyclist to quickly affix the removable shoe sold to the bottom of his or her cycling shoes and walk or run across ground surfaces having low traction. The traction means may comprise ridges and valleys or similar means for engaging low-traction ground surfaces. The removable shoe sole may be made of durable material and affixed to a cycling shoe using off-the-shelf fasteners such as will be familiar to one of ordinary skill in the art.

Functional shoes include a sole, a coupling member including a coupling body detachably coupled to the sole; an auxiliary lever coupled to the coupling body so as to be rotatable toward a bottom surface of the sole; and a fixing part protruding from the auxiliary lever toward the bottom surface of the sole and is detachably coupled to the sole, and at least one functional member provided integrally with the coupling body or detachably coupled to the coupling body to provide a predetermined function to the shoes. The fixing part moves between a coupling position in which the fixing part is coupled to the sole and a separation position in which the fixing part is separated from the sole, by a rotation of the auxiliary lever.
