The No Ridge Plus Active Socks are designed for wear by individuals with swollen or sensitive feet. Designed so no seam digs into the toes and with padded heels, toes, and soles to protect against pressure sores, these socks have an anti-microbial finish and a spandex ankle panel for extra support. The knit construction transports moisture away from the skin. Made of cotton, acrylic, polypropylene, nylon, and spandex, the socks may be machine washed and tumble dried. SIZES: Small/medium and large/ extra large. COLOR: White.
