Ski Crampons are like life jackets - you might go years without needing them, but when you do you REALLY need them. For icy or windblown conditions where you just can't get enough edge bite to stick to the slope, the Dynafit Ski Crampons are lifesavers. Compatible with Dynafit and other tech bindings, these ski crampons can be inserted or removed without taking off your skis. These crampons are available in a variety of widths, so make sure you order the size that will fit over the waist of the skis you intend to use. For best penetration of the teeth, use the low or medium climbing levels of your bindings.
