During a run, the circulation system operates on full throttle. The muscles require mmore nutrients, the pulse increases, the whole cardiovascular system speeds up- hard work for the body! X-SOCKS Run Energizer support the body through gradual compression and help the calf-muscle pump get a jump start: the stronger compression in the foot area allows the blood to more easily recirculate. This accelerates the blood circulation, relieves the cardiovascular system and reduces the heart rate. This saved (accumulated) energy is ready for the athlete to use in performance.
