The Power Wrap is the stiffest liner in our collection. High-density foam construction & additional reinforcement around the cuff & ankles providing maximum stiffness & heel hold. The Power Wrap (medium volume) model have a medium/low volume sole & can easily accommodate a footbed if desired. These customisable liners will stiffen up any boot & are suitable for a variety of ski applications. The ultimate performance booster for extreme responsiveness & superior edge control. For best results we recommend having these liners heat molded at a shop by a professional bootfitter. Stiffer models require more attention when heated, while others can be easily molded by using the home fit kit.
