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.

A skate with a stowable and/or removable roller, blade, ski, or track assembly. A skate has: a shoe; a guiding part mounted to the shoe; a roller, blade, ski, or track assembly mounted to move along the guiding part between a deployed position and a stowed position adjacent a calf or ankle part of the shoe; and a handle connected to move the roller, blade, ski, or track assembly between the deployed position and the stowed position. Related methods include moving the roller, blade, ski, or track assembly between the positions, and locking or unlocking the assembly in either position, for example using a handle.

In a first aspect, a wearable device is provided for mounting to a foot of a user. The wearable device includes a support structure having a longitudinal axis, and having an interior. The support structure is positioned to support a foot of a user, wherein the support structure has a ground engagement surface. The wearable device further includes a first wheel shaft having a first wheel connected thereto, and a second wheel shaft having a second wheel connected thereto. The first and second wheel shafts are connected to the support structure and are movable between a stowage position in which the first and second wheel shafts hold the first and second wheels above the ground engagement surface and a rolling position in which the first and second wheel shaft hold the first and second wheels below the ground engagement surface. In both the stowage and rolling positions, the first and second wheels are laterally outside of the interior of the support structure.
