Get more energy, stamina, and performance with this pair of women's CEP compression socks--ideal for runners, triathletes, and endurance athletes. The graduated medical grade compression is designed to penetrate deep veins, flush out lactic acid, and support muscles, tendons, and the Achilles. Additionally, targeted consistent compression focuses on arterial blood flow for better performance and reduced muscle vibration for heightened agility. The socks are made from an all-synthetic temperature-regulating material (85 percent polyamide and 15 percent spandex) for comfort in any weather condition. Other features include anatomic foot padding, extra-flat toe seam, odor-reducing silver ions, and anatomical fit. They're backed by a 30-day comfort guarantee and a 60-day compression guarantee.
