The Klimatex TON compression knee socks are made using a functional material for fast drying, lightness, comfort and good thermal regulation. The special funnel construction ensures varying compression levels. Compression is the strongest round the ankle and then gradually eases moving upwards - it is a so-called gradual compression. This effectively helps with blood flow towards the heart. The socks improve blood flow in the muscles, oxygenation, decreasing muscle tissue damage and help reduce fatigue. They also help to speed up calf muscle recovery, decreased swelling and muscle pain. Tested by professional sportsmen. Suitable for demanding activities - triathlon, cycling, running, marathons. The knee socks are also great for longer periods of standing up or sitting down as they prevent the swelling. That makes them perfect for long distance travelling either by car, bus, or a plane. They can also be used as a preventive measure (support of blood flow, minimum shock). If used during races we recommend putting them on about 3 hours prior to the start. For recovering from fatigue the socks should be worn about 3 more hours after the race or until the pain is gone.
