The Comfort Bio-Wick® Single Ply Prosthetic Sock is a unique one ply equivalent thickness seamless sock. The CoolMax® interior wicks moisture away from the skin keeping the wearer dry and comfortable. Moisture is transported to the Cotton outer layer of the sock where it can transfer the moisture to the air or to another sock. The Bio-Wick® sock provides great comfort thanks to the exceptional stretch that allows conformity to virtually any shape. The non-run construction allows the sock to be cut to length without unravelling.
