DD TRT 12 Liner | 2025

The TRT DD12 liner has a dual-density tongue that enables a wide range of motion that’s perfect for touring and telemark boots. This lightweight alternative to stock liners is made of proprietary Intuition Foam, cuff-to-toe, and combines thicker density in the cuff with a softer foam in the forefoot, both of which are heat-moldable for a fully-personalized fit. The tongue of the TRT DD12 comes with asymmetric padding for an ergonomic feel as you make your way through the mountains, as well as a speed lace system that locks you in for a rewarding descent. For longevity, an antimicrobial treatment keeps them smelling fresh, run after run, season after season.
