PRO TONGUE liners are the first tongue style liners Intuition created that can compete with the Power Wrap in stiffness. They're ideal for most shells used by intermediate and advanced level skiers and riders.

This high-density, medium thickness liner features a 2mm Strobel sole, with removable 7mm foam insoles, and a roomy toe box to accommodate various foot volumes and widths in tighter fitting shells. 

They recommend having these liners heat molded at a retail shop. Available in sizes: 4-15 US / Mondo 22-33 Size down on the half size, for example: 9.5/27.5 = 9/27
