Therafirm's SmartKnit socks are ideal for diabetics, people with sensitive skin or any condition where protection from irritation is important. These patented SmartKnit socks are completely seamless to prevent blister-causing pressure points. The form-fitting design does not wrinkle or bunch up and the “halo top” prevents leg indentations and reduces the chances of circulation restriction. The X-STATIC silver fibers in the Black, Navy and Grey colors prevent odor. SmartKnit is available in knee, crew and mini-crew lengths. SmartKnit is made in the USA.
