Compression Socks - Designed with unique 3D knitting technology to provide support and compression around the arch of the foot. The graduated compression stimulates blood flow, decreases inflammation and swelling, and helps to alleviate pain and discomfort from plantar fasciitis, heel spurs and Achilles tendonitis. Premium Materials - Made from a breathable Nylon/Spandex blend, our moisture-wicking fabric keeps feet dry to provide all-day comfort. The wide, anti-slip band keeps our socks in place so the cuff wont roll, move, or dig into your skin. Wear with Any Style of Shoe - The open toe design wont restrict or compress your toes so they can be worn without socks in high heels, thong sandals and other open toed shoes. Wear them under socks in work boots, sneakers or sport skates. Available in sizes M, L and XL - Please see the size chart within our product photos to choose the correct size sock for you.
