Power to the top: Our trail running socks support your calves with targeted compression, especially when the trails get steeper and the terrain more difficult. Thanks to Targeted Compression Zones, your muscles get the decisive boost when they need it. The Run Ultralight Compressions Socks are our running socks for highest performance. The ultra-light socks provide optimal ventilation, fit like a second skin to your foot and ensure high comfort even in warm climates. Optimal energy management and high breathability thanks to the wide mesh knit Run Ultralight Compression Socks combine the best features of lightweight sports compression stockings: the ultra-thin knitted fabric is particularly breathable and thus ensures a pleasant running feeling - even on warmer days. Integrated compression zones support the muscles in the calf and stabilize the ankle and foot. Unique compression zones on the calf reduce muscle vibration and stimulate blood circulation. As a result, the muscles tire more slowly when running and more free energy reserves remain. The "Infinity Zone" offers protection against overloading: it slightly lifts the arch of the foot and supports the ankle joint with light pressure. The "Relief Sole" and "Heel Protection" comfort zones protect the sole of the foot and reduce the pressure load on the heel when the foot is placed in the running shoe. The "Achilles Comfort" recess relieves the Achilles tendon and prevents over-irritation in this sensitive area. The correct size of Run Ultralight Compression Socks is determined by the shoe size and calf circumference at the strongest point. This means that the sports compression socks fit the skin perfectly and have an optimal effect. They are manufactured in Germany to the highest quality standards.
