PRO TOUR liners are best for back-country, tele, and touring applications. A lace up, tongue style liner available in 3 Volumes: HV (High Volume, thickest), MV (Medium Volume), and LV (Low Volume, thinnest), to accommodate a range of shell fits. These dual-density, light weight liners feature a softer flexing lay-up, and a roomy toe box for maximum comfort on long tours. The strategic rear panel increases range of motion for tour-ability while the stiff upper cuff offers solid support and responsiveness, enhancing performance both ascending and descending.
The Pro Tour liner has the option of replacement tongues…the Flex Tongue which comes stock in the Pro Tour or the Power Tongue. The Flex Tongue is stiff at the top with flex at the bottom. The Power Tongue is stiff all the way down. The Flex and Power Tongues are available in Medium and High Volume thicknesses. Check out our replacement PRO TOUR TONGUES
