The Run Lightweight No-Show Wool was built for comfort, feel, and performance across a range of temperatures, distances, and terrains. This ultra-thin, minimalist toesock packs in the benefits of Merino wool, with superior softness, exceptional odor resistance, and temperature regulation. Plus, five-toe technology allows your toes to align and splay naturally. The no-show length rests below the ankle and features a heel tab to protect against chafing and keep the sock from sliding into the shoe.
