Buckle in for power and warmth. The Allspeed Pro Heat features the same customizable power and precision as the regular Allspeed Pro but with a heated liner to keep your feet warm in all conditions. The heated liner is pre-shaped to match the natural curves of your foot and is bluetooth compatible for on-the-fly temperature adjustment from your phone. The 100mm last balances comfort and control, while the Sensor Blade shell is engineered for reduced weight and efficient energy transfer to the ski. An adjustable flex lets you customize the boot to match your skiing.
