Vibram’s Trick sole for freeride ski boots is now available on Nordica’s Ace of Spades boot. The Trick sole combines rubber and TPU, and the overinjected anti-perforation TPU increases heel braking power and helps the boot release from the ski if the wearer falls. Vibram came up with the Trick when it found that 30 percent of winter sports accidents happen not on the slopes, but while walking around, because of the slippery plastic soles of most ski boots. The Ace of Spades boot is lightweight and provides grip and shock absorption for safer freeriding.
