1. Gradient compression process, socks adopts four-stage compression design from top to bottom to upgrade the pressure to adapt to the pressure requirements of different parts 2. The role of human circulation: accelerate the blood circulation, increase the venous blood flow of the human body, let the venous blood quickly return to the heart, increase the arterial blood flow, so as to improve the blood oxygen content, enhance the fatigue resistance, accelerate the metabolism, faster recovery of physical fitness, in order to achieve excellent sports performance 3. Effect on human muscles: reduce muscle vibration (muscle vibration is one of the main causes of fatigue) while not appearing tight feeling, which is mainly due to the gradient pressure value of MEDI compression technology, so that the compression force is ergonomic design, the compression force shows a gradient decline mode 4. Socks body arbitrary wool ring, in the movement of shock absorption buffer effect; Heel leg protection, arbitrary hair ring can prevent heel wear; Foot massage to promote blood flow and protect the sole of the foot 5. For those who want it: Our copper immersion clothing is designed to improve performance, help speed recovery, and relieve injuries and inflammation. It provides optimal joint and muscle support and makes you feel great. This is a real necessity for people who work on their feet for long periods of time, or who invest heavily in a sports and fitness lifestyle. Makes a great gift for joggers, athletes, fitness enthusiasts, office workers, runners, nurses and doctors.
