An evolution of the Cramp-O-Matic system which utilizes the C-O-M rear bale and lever. The plastic harness system is hinged from two front posts which retain the boot securely even if it has a shallow, worn front welt or overboots are being used. It is a simple and efficient binding, which is far more versatile than the original Cramp-O-Matic style. The harness is made from the strongest, most durable plastic available, which was developed for the manufacture of alpine ski bindings. Obviously it cannot last forever, so please, after long and severe use replace the harness the same way you would resole trekking boots or rock climbing shoes.
