Abstract: A boot oversole and carrier attachment for boots, such as ski boots, provides several advantages. The boot oversole is characterized by a wedged thickness which compensates for the unnatural leg angle imposed by ski boots. A pair of oversoles may be easily attached to ski boots for improved walking and protection of the boot soles, and may be easily removed for normal skiing operation. The tread of the oversole is preferably of dovetail grooves to provide good traction and to allow the oversoles of a mating pair to be easily interlocked. A handle and a storage base are provided on each oversole without interfering with the walking characteristics, for conveniently carrying and storing a pair of boots mounted on the interlocked oversoles.
