Stump socks help remove odors, oils, and other contaminants. They also contribute to reducing pain by filling in spaces (volume) where the amputation has shrunk. Stump socks come in two basic varieties: above the knee stump socks (AK) and below the knee stump socks (BK). The Stump Socks are made from certified high-quality yarns and are delivered pre-washed. The skin will not be stressed with residuals. The products are washable by machine at the state maximum temperature and are dryer-proof.
