A locomotion device includes a chassis adapted to accommodate at least one user and which is supported-by ground engaging members. At least one of these members is mounted on a steering column articulated with respect to the chassis about an axis of rotation. The device includes a frame kinematically connected to the steering column and movable with respect to the chassis and adapted to come into contact with the ground with the frame making it possible to control rotation of the steering column about its axis.

The ice skate of claim 2 and further comprising: a bushing insertable within the first slot; a threaded screw insertable through the bushing; a nut having a rectangular configuration to threadably engage the screw, the nut disposed with in the recessed surface; and wherein the threaded screw and bushing are positionable through the first slot to slidably secure the toe box to the blade holder frame. 4. The ice skate of claim 1 wherein the downwardly extending channel walls are resilient. 5. An ice skate comprising: a blade holder frame having a forward section; a boot disposed on the blade holder frame, the boot having a heel portion and a slidable toe box portion, the toe box portion having first and second downwardly extending channel walls, the forward section of the blade holder frame extending between the first and second channel walls; first and second detents disposed on either the forward section of the blade holder frame or the first and second channel walls; a plurality of indentations disposed on either the forward section of the blade holder frame or the first and second channel walls; wherein the toe box is locked into a selected position upon the first and second detents engaging the plurality of indentations; and wherein the first and second detents engage the plurality of indentations upon flexing the first and second channel walls toward the forward section of the blade holder frame. 6. The ice skate of claim 5 wherein the heel portion comprises left and right vamp sections, the left and right vamp sections engaging an outside surface of the toe box portion. 7. The ice skate of claim 5 and further comprising; a first slot disposed within the toe box portion along a longitudinal axis of the skate, the slot having a perimeter wall extending downward; and a recessed surface to receive the perimeter wall of the first slot, the recessed surface disposed longitudinally within the blade holder frame along the longitudinal axis of the skate, the first slot and the recessed surface slidably engageable with one another such that the toe box may slide rearwardly or forwardly guided by the perimeter wall. 8. The ice skate of claim 7 and further comprising: a bushing; a threaded screw insertable through the bushing; a nut having a rectangular configuration to threadably engage the screw, the nut disposed within the recessed surface; and wherein the threaded screw and bushing are positionable through the first slot to slidably secure the toe box to the blade holder frame. 9. The ice skate of claim 5 wherein the blade holder frame includes a slotted aperture extending therethrough and the side channel walls include apertures alignable with the slotted aperture, and further including a locking member extending through the apertures of the side channel walls and the slotted aperture of the blade holder frame, the locking member flexing the side channel walls toward the forward section of the blade holder frame to engage the first and second detents with the plurality of indentations. 10. An ice skate comprising: a blade holder frame for holding an ice engaging blade, the blade holder frame including a recessed surface disposed longitudinally along a longitudinal axis of the skate; a boot comprising: a heel portion disposed on the blade holder frame; and a toe box portion slidable on the blade holder frame, the toe box portion including a first slot disposed longitudinally along the longitudinal axis of the skate, the first slot including a perimeter wall extending downward; wherein the perimeter wall of the toe box portion seats within the recessed surface of the blade holder frame to slidably guide the toe box portion rearwardly or forwardly to adjust the length of the boot; and wherein the locking mechanism comprising: first and second channel members extending down from the toe b
