The four-buckle fastening guarantees a precise fit and power transmission from boot to ski. They force considerable knee flex, making them suitable for advanced skiers who want to ski sportily. The fourth buckle usually has a sealing function. Fastening should start with the second buckle, then fasten the first and move on to the lower buckles.

The ski/walk switch design allows the upper to be set into downhill mode or walking mode. This makes it easier to put the boot on, but most importantly it allows you to walk comfortably, as the upper then has a much greater range of movement.

The systems used and specially developed technologies allow the shoe to be precisely tailored to the structure of the foot. This translates into increased stability while riding, control, safety and high comfort.
