Tights specially designed to speed recovery by increasing blood circulation in the legs. If you have problems with swollen feet or legs you can also use these all day as regular tights. For the best recovery, you can sleep in them, they are comfortable and soft. The heavy duty fabric provides graded compression, leading to increased blood circulation and faster recovery. The vibrations and strokes of the muscles are reduced as you run and thus the muscles do not become as stiff and tired. The tights have flat seams to counteract scuffs, temperature-regulating properties and are also antibacterially treated.
