The OS1st FS6 Performance Foot Sleeve provides relief from plantar fasciitis using support and graduated, medical-grade compression. This foot sleeve stabilizes the Achilles and keeps the plantar fascia compressed and stretched, encouraging better circulation and providing structure to help alleviate the heel and arch pain that comes from plantar fasciitis. OS1st's Compression Zone Technology applies varying levels of pressure to six different zones, giving you just the right amount of compression in each area to promote circulation and hasten recovery while keeping you comfortable at rest or during workouts. With a slim profile, the OS1st FS6 Performance Foot Sleeve can be comfortably worn under another pair of socks. During workouts, moisture-wicking fabric helps keep the sleeve on securely, preventing chafing and making sure it stays in place no matter what you're doing! It's also great for resting, allowing your feet to heal while you're sleeping. You can purchase them as a single sleeve or a pair.
