K2 Liner- Powerfit Pro Tour

Heat-mouldable touring performance with a precise, supportive fit for the climb and descent.

The K2 PowerFit Pro Tour Liner balances touring mobility with the firm support needed to drive freeride ski boots confidently. It is pre-moulded and lasted with Ultralon heat-mouldable foam, allowing the fit to be further shaped around your foot. Stiffer foam, a high-density power collar and a rigid asymmetric tongue improve energy transfer when pushing through variable snow and demanding terrain. Pre-moulded ankle pockets create a secure, locked-in feel around the heel, while the rear tour notch gives the ankle more freedom during bootpacks, approaches and long days on the skin track. The result is a performance-focused liner that remains comfortable while moving uphill without sacrificing control on the descent.
