The Dynafit Kit Semiautomatic is not a ski crampon. It is a replacement front bail for boot crampons: a steel and rubber toe harness, supplied as a pair, that converts the Dynafit DNA and Mezzalama crampons from fully automatic to semi automatic.

• Not a ski crampon: it does not fit a binding and it has no ski width sizing.
• What it does: converts a fully automatic crampon, which needs a toe welt on the boot, into a semi automatic one that works on boots without a toe welt.
• Compatibility: Fits the Dynafit DNA and Mezzalama crampons only.
• Front bail: Steel and rubber front bail, supplied as a pair.
• Origin: Made in Italy.
• Not ski crampons: If you want Dynafit ski crampons, those are a separate product, sized by ski width from 80 to 130 mm.
