COMPRESSION SOAKS - L/XL FOR ONE is a high-quality breathable nylon material that acts as an anti-friction to stabilize joint position. It helps reduce muscle vibration and accidental injuries, so that joints and muscles are in a stable state. COMPRESSION SOCKS have a pressure curve from top to bottom which increases oxygen supply. It also comes with half-moon-shaped wing on both sides of the sock, (using arbitrary loops) to cushion and protect the ankle and leg muscles. Very suitable for mountaineering, running, fitness, cycling, basketball, football, high jump and other sports. It is sweat absorbing. To Use: wear your compression stockings during the day and take them off before going to bed. Put them on again first thing in the morning. You should be given at least 2 stockings, or 2 pairs if you're wearing them on both legs. This means you can wear 1 stocking (or pair) while the other is being washed and dried.
