ABSTRACT:
An improved boot for use in ice and snow conditions that combines a flared snowshoe-like secondary sole with integral and selectively deployable crampons. The expanded secondary sole extends approximately ¼″ or more down from the primary sole of the boot and includes retractable crampons attached to the expanded sole to increase traction in snow or ice. The expanded sole functions to increase the surface area of the “footprint”, thereby reducing the overall depth of the footprint and making traversing in soft conditions (snow, mud, sand) less fatiguing to the wearer. The crampons may pivot outward from inside pockets in the secondary sole or, alternatively, may slide outward in a stiletto-fashion and/or unfold. The crampons may be individually deployable or simultaneously deployable by a central release button.
