RFL Thermolite OTC Ultra-Lightweight Sock

What Our Gearhead® Experts Are Saying:

"I switched to the RFL Thermolite OTC Ultra-Lightweight Sock for a week of resort riding, and my boots felt more responsive right away, less bulk between my foot and the liner. My feet stayed comfortable from first chair to last, no hot spots and no slipping."

Every good day on the mountain starts at the bottom of the lift, buckling into boots that fit exactly right, and the RFL Thermolite OTC Ultra-Lightweight Sock from Darn Tough is built for that first step. Picture stepping into your bindings, foot locked in tight against the liner, boots responding the instant you tip into a turn instead of a beat behind.

Knit from lightweight synthetic Thermolite fibers, it stays low profile enough to preserve that direct boot connection while still trapping enough warmth to keep toes comfortable through a full day out. A True Seamless Toe removes friction points before they start, and a reinforced Achilles panel keeps the sock from sliding down inside the boot, run after run.
