American Meb Keflezighi just won the Boston Marathon in 2 hours, 8 minutes, 37 seconds. And what exactly was Meb wearing as he ran across the finish line? CEP Compression Socks!CEP Progressive Run Socks are hugely popular with marathon runners. They provide 20-30 mmHg of moderate compression, which is ideal for performance socks. Moderate compression enhances circulation so muscles are quickly rejuvenated with fresh oxygen. These compression socks also support and stabilize leg muscles to prevent injury during long, intense runs. CEP, one of the best performance sock brands, also sells calf sleeves (without the foot portion) and recovery socks for both men and women. Learn more here.
