Alchemist RX Compression Socks (Men, Women) – For Running, Cycling, Basketball, Training, Flight Travel and Recovery of Swollen Legs and Feet, Shin Splints – Black Knee High Stockings, LARGE

RACE, RECOVER, FASTER. It's not dope, but it may as well be. The Alchemist Design Lab formulated these performance-enhancing compression socks to reduce fatigue and speed recovery. Developed by Alchemist Founder, Endurance Racer, and ER Doctor, Jeff Wu, M.D., the Rx Compression Socks are like a prescription to go FAST. Sizing based on men's shoe sizing: Small fits 7 and under. Medium fits 7.5-10. Large fits 10.5 to 12. X-Large fits 12 and over. Consider adjusting sock size based on relative calf size. i.e. If you have larger calves, consider ordering a size larger. THE SCIENCE: Rx Compression Socks were carefully designed to provide 40mmHg pressure in the hind foot and ankle, gradually decreasing to 30mmHg as the sock travels up the lower leg. When worn during activity, the graduated compression enhances blood flow(1), which helps oxygenate muscle tissue and delays anaerobic metabolism. The result is enhanced performance.(2,3,4). Furthermore, decreased blood lactic acid levels were found in athletes exercising at maximal intensity(5,6). This increased lactic acid clearance shifts the Lactate Threshold curve to the right, essentially reducing Lactate accumulation during a given power output. A notable decrease in heart rate at maximal exertion was also documented(7). Compression socks also improve performance by dampening muscle vibration, reducing muscle soreness and fatigue. Increased muscle support results in reduced vibration and improve leg power(8,9). After exceptional activities, compression garments have been found to improve muscle soreness and recovery.
