The Radical ski touring boot features the revolutionary Hoji Single Lock System and is an uncompromising all-rounder both uphill and down.
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. 
With these on, you will be ready to tackle long tours with many meters of climbing. Once at the summit, the Radical boot becomes a sturdy downhiller with top power transfer, thanks to the one-hand handling for the patented Hoji Single Lock System. Flip the lever of the ski-walk mechanism and the entire system is tensioned, setting the boot in a forward lean angle of 11 degrees. Cuff and shell combine to create a positively locked unit that transforms the revolutionary system into one unit totally without play. 
They secure the foot safely and firmly, lending a flex index of 110 even on challenging downhill terrain for all-around impressive downhill performance on the skis.
The new Radical is compatible with all pin, hybrid and alpine bindings.
