Technologically advanced from the composition to the cuffs and through to the toes, the incredible X-Socks Trekking Light Limited Socks, with a total of 14 integrated, patented functions, represent the latest generation of Swiss-engineered, performance enhancing legwear, using every bit of their potential to give you the advantage. The yarn is a combination of many fibres, including hollow-core Robur for breath ability and cushioning, while skin-neutral, anti-allergenic lightweight Mythlan fibre counteracts germs and bacteria. A unique 'Partial-kompression®' fit maximises muscular control while also ensuring that the cooling function of the skin is simultaneously maintained for a 'barefoot' climate that relieves strain on the body. Protection and stability zones are placed throughout the foot, at the instep, heel, ankle and toes, provide security on any surface.
