This is the update to Ironman's previously successful Endurance Pro Knee High Compression Sock.
Built for superior support and comfort. Delivers a pro-rated breathable second skin fit that assists with venous return, blood back to the heart, and supports muscles and soft tissues. Reduces excessive muscle vibration which is a significant cause of fatigue. Lightweight fabrics maximum moisture control. Seamless toe enclosure. Great for race day or post workout recovery.
