Le Bent's signature blend of Merino and Rayon from bamboo makes up the base for this low-profile but high-performing sock designed and worn by the pros. Both materials are slightly magic, with the ability to wick moisture and stay warm while wet. With just a touch of cushioning on the shin and that's it, the socks have a precise fit under the boot. Replete with instep, ankle band, and Achilles support, they will be sure to stay in place and avoid bunching.
