The Radical ski touring boot features the revolutionary Hoji Lock System and is an impressive all-rounder with uncompromising performance 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. Its low weight and flexible tongue construction made of two different high-tech synthetics ensures an energy-saving, natural walking movement even on steep terrain.

The new thermo-moldable boot liner (optional) offers stability and comfort with a perfect fit right out of the box. With these on, you will be ready to tackle long tours consisting of what would have been grueling climbs. Of course, with the Radical, you're going to be saving some serious reserves for the descent. Once at the summit, the Radical becomes a sturdy downhiller with top power transfer, thanks to the one-hand handling for the patented Hoji Lock System. In ski mode, the boot is set in a forward lean angle of 11 degrees. The ski-walk system’s mechanism is integrated into a cable system together with the buckles and the Ultra Lock Strap. Flip the lever and the system is tensioned. The polyurethane cuff and shell combine to create a positively locked unit that transforms the revolutionary ski-walk system into one unit totally without play. A unique feature on the market for precision and efficient skiing of the highest level that was normally seen only in purebred Alpine ski boots.

In contrast to the Radical Pro, the Radical’s ski-walk mechanism is not connected with the micro-adjustable buckles and the strap. Rather, these must be secured separately for the descent. 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.
