Roller-skates/sneakers with two pairs of separable wheels, by which the problem of their alternative adjusting for walking or roller-skating is solved, and which are at the same time safe, maneuverable, practical and simple to manufacture. The roller-skates consist of sneakers, which are laced with laces, an insole and two pairs of wheels separably fixed in the insole. The insole, which follows the shape of the foot and contains the front and rear axle and forms the load-bearing construction, is built into the lower part of the sneaker inside the sole. The wheel consists out of the middle plate lined with silicone rubber, an interchangeable mask, two bearings on the rims of central hollow part of the wheel, as well as two washers made of steel with two lids on the side of the wheel facing the sneaker.

Disclosed is a power-driven shoe. The shoe includes a shoe sole having a plurality of rotatable wheels arranged below the shoe sole in an overlapping fashion. The distance between the rotational axis of the wheels is less than or equal to the diameter of the wheel, such that vertical obstacles can be overcome in both the positive and negative displacement directions for increased ground stability. The shoe sole includes a toe part and a sole part that are connected to each other, via a hinge, in both a rotational and translational configuration, such that at least one front wheel or at least one middle wheel are independently in contact with the ground while maintaining at least one rear wheel in contact with the ground throughout a bi-pedal gait cycle, allowing for comfort during a user's natural range of motion.

A ground-engaging device that is capable of sustained rolling, stable braking, secure standing, and walking. In one preferred embodiment, the invention relates to a wheeled footwear device. In another preferred embodiment, the invention relates to a wheeled footwear platform. In yet another preferred embodiment, the invention relates to a wheeled artificial foot.

The present invention concerns the field of garments, namely the shoes sector, especially relating to children, although it is likewise applicable to young people and adults. The object of the present invention is an outer sole (1), on which are inserted two structures, a first one enabling one user to slide when he is contacting the ground, moving as if he were on skates, and a second one enabling the user to move in a conventional way. The first structure, which enables a movement in a rolling mode, consists in a frame (2) containing a wheel (3) and, on one end, presents a front locking member (4) and, on another end, a locking member (5) for disengagement of the frame (2) by pressing downwards.

There is provided a guard for an in-line roller skate, which includes an elongated member defining a wheel receiving channel. The channel has a bottom and a pair of opposed sidewalls, which extend upwardly from the bottom terminating in a remote edge. The remote edge of the sidewalls define a wheel insertion opening to receive wheels of an in-line roller skate. At least one transverse roller is positioned across the channel near the remote edge of the sidewalls.

A device configured for use within a dedicated footwear is provided comprising a wheel housing, a removable wheel cover, and a deployable wheel member for multi-dimensional functionality of the footwear. The wheel housing may reside within the heal portion of the sole of the footwear. The removable wheel cover may cover the wheel housing within the heal portion of the dedicated footwear, so that a user may optionally cover the wheel housing when wearing the footwear without the wheel functionality. In addition, the removable wheel cover may optionally be removed from the wheel housing, so that the user may insert the deployable wheel member within the wheel housing, so that the dedicated footwear provides rolling functionality. A user may easily remove the deployable wheel member from the wheel housing to cover the wheel housing with the removable wheel cover and return to footwear to traditional use without the rolling functionality.
