An apparatus, in its first, second, and third embodiments, that is intended to be temporarily attached to the soles of ski boots, whenever the wearer is not attached to skis and desires the ability to comfortably walk or desires protection for the soles of the ski boots. The first three embodiments generally comprise of sandal-like soles made of a resilient, elastic, springy material, which aids in the natural walking action by alternately compressing and releasing, adding energy to the step, thereby aiding walking while wearing ski boots. A fourth embodiment is made by altering the ski boots themselves so that the heel (41) and toe (40) sections of the boot are hinged (42) to the underside of the boot, and contain a spring that adds energy to each step taken by the user. The hinged sections are pinned against the boot while skiing.
