An easy-wearing skate is provided, wherein the easy-wearing skate includes a boot having a chamber open upward, the boot further includes a fixed shell having a rear opening, and a movable shell rotatably connected to the fixed shell and configured to cover the rear opening, the movable shell is swingable away from the rear opening, a first tightening strap is connected to a side of the fixed shell, a locking device is connected to another side of the fixed shell, the first tightening strap is releasably locked by the locking device, and as the first tightening strap is released from the locking device, the movable shell can swing away relative to the fixed shell.

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.

A locomotion device on castors including: at least one castor mechanically connected to a sole to roll along a ground, the castor being mounted to rotate about an axis of rolling parallel to a plane of the sole and also about an axis of rotation perpendicular to the plane of the sole; a controllable electromechanical braking device configured to apply a braking torque to the castor that varies according to a braking command received; an inertial unit configured to measure a physical parameter indicative of a steering angle; and a central processing unit programmed to establish the braking command according to the physical parameter measured by the inertial unit and to transmit the established braking command to the braking device to apply to the castor a braking torque that varies according to the steering angle.

A wearable motorized device comprising a shoe bracket, which can be fastened to a shoe; wheels that are installed on the left and right sides of the shoe bracket in parallel to support the wearer's lateral skating and longitudinal walking; a driving motor for rotationally driving the wheels; and a battery pack for powering the driving motor. The wheels are not coaxially installed on the two sides of the shoe bracket to drive the wearer's longitudinal skating, but instead are installed on the two sides of the shoe bracket in parallel to drive the wearer's lateral skating; the wearer can position his/her legs apart during skating, so the skating stability is improved. Its general contour does not significantly exceed the contour of the shoe in the longitudinal direction, thus and it will not strain the wearer when ascending or descending stairs.
