The Radical ski touring boot for men features the revolutionary Hoji Single Lock System and is an uncompromising all rounder both uphill and down. The boot modeled after the Radical Pro model combines the seemingly contradictory worlds of freedom of movement on the ascent and rigidity for the downhill. In walk mode, the cuff and shell are separated from each other to be able to climb efficiently with a 60-degree cuff rotation for unrestricted, resistance-free mobility.
