Dynafit ST Radical

The Dynafit ST Radical is a long-standing favorite for classic ski touring, known for its durability, comfort, and ease of use. It is a dependable all-rounder that performs equally well on local tours and longer, high-alpine missions.

The Step-In Side Towers make toe entry more than 30 percent easier, helping you get moving quickly while improving lateral stability on the descent. A reinforced aluminum heel unit increases rigidity and power transfer, giving the binding a solid, predictable feel underfoot. Two climbing riser heights can be adjusted easily with a pole, and 25 mm of length adjustment allows the binding to accommodate different boot sole lengths.
