The Inferno 90 offers the junior racer or smaller advanced to expert skiers and racers power and sensitivity. The 90 is derived directly from our World Cup Race boot with the same stance in a 98mm semi-plug design but with a lower cuff height and in a 90 flex. Offers great feel, sensitivity and power to the edge. Dual Cuff alignment, flex adjustment and removable velcro rear spoiler offer personalization and performance enhancement. Quick Instep makes this the first low volume boot that is easy to get on and off.
