LIGHTWEIGHT, TECHNICAL PRECISION. THE RACING MACHINE . The X-SOCKS® Ski Precision is a real competition sock. As a supplier to national ski teams, many national team professionals trust the technology in X-SOCKS®. Biathletes, downhill skiers, Nordic combined skiers and so on, for every extreme physical stress situation in high-performance sport, X-SOCKS® has tailor-made technology for professional feet. All our experience in high-performance sport has been transfered to the X-SOCKS® Ski Precision. They provide warmth for the larger muscles in the calf with Merinowool and, thus, guarantee the unrestricted availability of muscle performance. The padded zones on the shin, ankle, Achilles tendon, heel, toes and instep provide the necessary protection. The proven X-Cross® Bandage is responsible for providing stability. But the most noticeable feature of these socks is that they are very thin. High-performance athletes demand thin socks because they know how important contact to the ski is in order to be able to call on accurate muscle reaction.
