Intuition Pro Tour HV Ski Boot Liners

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 alternate tongues and the supple cuff offer solid support and responsiveness, enhancing performance both ascending and descending.

This is the High Volume liner.
