Run Performance Compression Socks support the calf muscles and boost your performance every time you run. Targeted compression reduces muscle vibration. That is why when you run, your muscles get tired less quickly and have access to more of the larger energy reserves. The "Infinity Zone" section in the foot and ankle area supports the arch and prevents excessive stress during prolonged exertion. The comfort zones "Relief Sole" and "Heel Protection" protect the sole of the foot and reduce compressive loads on the heel when placing and supporting the foot in running shoes. The "Achilles Comfort" heel recess relieves the Achilles tendon and prevents excessive irritation. The compression socks for sports fit perfectly to the skin and are therefore extremely effective. To choose the right size, measure the calf size at its strongest point. The Run Compression Socks are durable, breathable and washable at 40ºC. They are manufactured in Germany under the highest quality standards, do not contain harmful substances and are skin-friendly
