Abstract

Crampons formed of straight-sided frame members with at least one such member on each side, but preferably joined together in pairs at each side for lateral and/or longitudinal adjustment to provide for changes in the dimensions of the crampon to suit boots of various sizes, or, if desired, articulation around a horizontal axis, further including integral depending pointed members located and arranged in an aligned configuration for the purpose of piercing snow and ice to provide additional traction for climbers and hikers, and preferably having improved means for quickly and securely fastening the crampon to a boot to stress the sole thereof and thus afford greater rigidity to the crampon.
