ABSTRACT:
A crampon removably attached to a shoe having a plurality of teeth oriented in an angled, noncolinear fashion, such as on the faces of a polygon, on both a heel and toe portion of the crampon. The toe portion of the crampon further includes a plurality of slots which receive a plurality of pick elements selected from a variety of interchangeable pick elements. The variety of pick elements includes a double flat pick, a single reverse angle pick, a flanker pick, a tooth claw pick and a novel tubular pick. The crampon according to the present invention provides enhanced traction by inhibiting a skating action resulting from the substantially linearly disposed teeth of prior crampon designs, while providing a maximum flexibility by interchangeably receiving a variety of pick elements.
