A tracked skate runner provides a low-profile substitute for a wheel with exceptionally low rolling resistance on rough or soft terrain. The runner includes a skate frame and rollers that bear against an endless track of hinged links devoid of pinch points that can get jammed with ground debris. The skate frame provides a channel with sidewalls and a top dirt shield. The sidewalls fit closely with the links of the track to seal out dirt, and the top dirt shield protects the rollers from dirt that shakes off the top recirculating portion of the track.

A motorized personal transportation article is described which transports a person by wearing a pair of power-assisted motorized shoes, wherein the shoes provide an increase in a user's walking speed in a forward walking action through supplementary motion of moving or propelling means based on an intended walking speed of the user, such that when a user's intended walking speed changes or when a user intends to substantially decelerate or immobilize, the speed of the supplementary motion can be adjusted before the step is completed. The sole of each of the shoes houses at least one plate coupled to moving or propelling means such as conveyor assemblies, and the moving or propelling means are designed to neutralize forces acting to disrupt the operation of the moving or propelling means during a forward walking action or the balance and comfort of the user.

An individual movement equipment item, which is constituted by a pair of motorized skates, each of the motorized skates comprising: a plate in the form of a sole and having a front portion, which is articulated transversely relative to a rear portion, the plate having means for connecting to the foot or the shoe of the user, motorized means, which are formed by two portions, which are articulated transversely in order to form a front train and a rear train, connection means between the articulated plate and the motorized means, which connect the front portion to the front train and the rear portion to the rear train, characterized in that the angle of the longitudinal axis of the at least one of the trains of each of the skates forms an angle between 10 and 20, and preferably of from 12 to 15, with the longitudinal axis of the plate.

A footwear assembly for use in a virtual reality environment comprising a front platform portion having an upper surface adapted and configured for supporting and releasably retaining the forward part of a user's foot and a rear platform portion having an upper surface adapted and configured for supporting and releasably retaining a rear part of the user's foot, the front and rear platform portions being joined by a transverse hinge so that the platform portions can pivot relative to one another to accommodate flexing of the user's foot, each platform portion having mounted under a lower surface thereof at least one drive motor, each drive motor driving a continuous belt, and two continuous belts on each platform portion being arranged substantially in parallel, one located to each side of the platform portion, the drive motor or motors and continuous belts of the front platform portion being mounted to a front drive module and the drive motor or motors and continuous belts of the rear platform portion mounted to a rear drive module, the drive modules being mounted beneath their respective platform portions so each drive module may rotate in the horizontal plane relative to the platform portion it is mounted beneath.
