A mobility device is provided and includes a base panel that supports a passenger. A plurality of wheels are disposed at a plurality of points of the base panel and are coupled to the base panel to be rotated with respect to a vertical axis. A rotary portion provides a rotational force to rotate the wheel with respect to the base panel. Additionally, a braking portion is disposed on the rotary portion to adjust the plurality of wheels to be rotated with respect to the base panel or positions of the plurality of wheels to be fixed.

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.

Disclosed is a sports equipment device, including a footwear portion with a sole, a transport portion including a frame and a movement mechanism fixed under this frame, and including a securing mechanism which is able to removably secure the footwear portion to the frame and which includes an upper front block and an upper rear block which are attached to the footwear portion, and a lower front block and a lower rear block which are attached to the frame and are able to be secured to the upper front block and the upper rear block respectively. At least a portion of the sole is created by molding and is molded onto the upper blocks.

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.

Disclosed herein is a retractable inline skate shoe. The retractable inline skate shoe is configured such that: a cavity is formed in the sole of a shoe body; the housing is mounted and fastened in the cavity; a slider is inserted into the housing; a push button is configured to protrude to an outside via a through hole portion formed in a heel of the shoe sole; a number of L-shaped wheel shaft insertion recesses are formed in lower portions of both left and right sides of the slider; a frame is mounted inside the slider; recessed wheel shaft fitting recesses are formed in both side wall surfaces of the frame; two fastening recesses are fastened onto the shoe sole; a guide is inserted into the frame; and the slider containing the frame is fastened into the housing by means of housing fastening plates.
