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 bifurcated truck in a laterally-sliding board wheel assembly enables the freeboard to seamlessly transition from carvingas associated with a traditional skateboardto new omnidirectional motions, in which the board can easy travel forward, backwards, sideways or in any other directional combination. The wheel assembly of this invention employs a bifurcated truck system having two independent suspension arms, both operating independently from one another and from the board's castering wheels. The wheel assemblies are mirrored at each longitudinal end of the board, resulting in the board's ability to carve, slide or skidand easily transition back and forth among each of these modesproviding the rider a sense of stability and freedom commonly associated only with snowboarding.

A rolling knee support device is attached to each knee of the user for support thereof when the user is in a kneeling position. The device has four swivel caster type wheels with a threaded stem for being releasably mounted into one of eight holes defined in a double-curved lower surface of a base of the support. The four wheels can be moved and arranged such on the double-curved lower surface so that the supporting feature of the knee supporting device can be modified and customized according to the needs of the worker and/or the particular job whereby the worker is supported in the most comfortable, balanced, and efficient position and orientation for any particular job. Straps with fasteners are used to secure each rolling knee support device to each knee of the user.

Provided is a ball skate sole structure which can be customized for each individual or each sport. This ball skate sole structure includes: a base plate having a plurality of first holes and a plurality of second holes; at least one ball roller member, the at least one ball roller member being disposed in the first hole selected from among the plurality of first holes; and at least one brake member, the at least one brake member being disposed in the second hole selected from among the plurality of second holes.

Disclosed is a bionic electric power-driven shoe, comprising a shoe sole (1), wherein a plurality of rotating wheels (2) are arranged below the shoe sole (1); an electric motor (3) is further provided at a lower part of the shoe sole (1); an output end of the electric motor (3) is connected to a transmission device in driving connection with the rotating wheels (2); and the shoe sole (1) comprises a heel part (11) and a sole part (12), the heel part (11) and the sole part (12) being in rotational connection.

An anti-slip footwear that can be used with an omnidirectional locomotion system or other virtual reality (VR) environment technology includes at least a sole layer and a rotatable traction portion. The sole layer includes an upper surface and a lower surface, wherein the lower surface includes one or more friction reducing elements having a first coefficient of friction with a platform of an omnidirectional treadmill. The rotatable traction portion is rotatably coupled to the lower surface of the sole layer and has a first face and a second face opposite from the first face. The first face includes one or more friction pads each having a second coefficient of friction with the platform of the omnidirectional treadmill that is greater than the first coefficient of friction. The rotatable traction portion can be rotated to a first, low-friction position in which the second face makes contact with a ground surface. The rotatable traction portion can be rotated to a second, high-friction position in which the one or more friction pads make contact with the ground surface.

The foot-attached exercise rollers comprises a toe cover, a strap, a plurality of rollers, and a plurality of grips. The foot-attached exercise rollers may be an exercise device that may be adapted to be worn on the foot. The toe cover may cover the front of a foot held in place by the strap. The plurality of rollers may be adapted to reduce friction between the front of the toe cover and a floor and the plurality of grips may be adapted to increase friction between the rear of the toe cover and the floor. The foot-attached exercise rollers may be adapted to be worn in pairs to exercise the user's core as a user moves the feet back and forth on the plurality of rollers while attempting to keeping the upper body still.
