Four zones of graduated compression
Graduated compression is the complex way of saying that the sock holds the greatest compression at the foot and lessens as you move up towards the calf. This promotes increased blood flow, which helps your muscles relax and encourages blood to move towards your heart to re-oxygenate. (Fancy term alert!) In athletes’ terms, this means more energy for longer and better workouts—and better recovery on those cherished rest days!
