Abstract
Abstract A skating vehicle (10) has a frame (16) with a blade (18) or rollers (20) mounted thereon and a boot (28) for mounting a detachable shoe (14) in a locked position thereon. The boot includes a rigid wall (19) which encircles the sole (15) of the shoe cradled within, and a rearward projection (64) in the toe portion which enters a slot (66) in the shoe sole when the shoe is inserted and moved forward, locking the shoe in the boot. A rear semirigid cuff (37) is lined with a padding whose lower edge is proximate with and communicates with the upper edge of the shoe during skating. The cuff is closed with an adjustable latch (44) which comprises the single means required to mount and dismount the shoe. The multi-use shoe includes a semirigid outer heel (142) attached to the sole (15) extremity and a semirigid outer tongue (140) overlying the shoe upper. A strap (144,148) attachment has one portion attached to the medial side of the upper and communicating with the outer heel to encircle the shoe heel, and a second portion passing from the rear portion of the sole on the medial side over the upper beneath the outer tongue. The free ends of the strap portions are adjustably attached to mount the shoe on the wearer's foot such as with hook and loop attachment material. The cuff collapses downwardly to reduce the skate size for portability.
