The lowest cut of all our socks-below the ankle bone-the Invisible Sock disappears in all our running shoes. Ribbing and silicone gel strips keep it from sliding, and a cushioned toe and heel counter keep the fit comfy. Only the protective back tab may be visible to cushion from friction and hint at what's inside. Features. Cushioned back tab. Nonslip silicone gel strips on heel. Targeted arch support. Cushioned toe and heel.. RN 88276
