The FDX Jigsaw Puzzle 20-30mmHG Compression Socks is a light weight sock made with a wonderful exciting pattern offering Compression Technology with an padded plantar fasciitis region which offers a thin mesh stripe which runs from the middle of the top of the foot to the bottom of the cuff, on both sides of the sock. The mesh, together with the light weight fibers, gives superior wicking and maximum ventilation during your daily use. The moderate compression is gradual, with the highest from the mid-foot to the top of the ankle, stimulating blood flow, increasing circulation, alleviating swelling, and contributing to a boost in performance and well-being.
