Some of our professional athletes are fans of full-length socks... Others prefer a lower cut, yet do not wish to compromise on efficiency and performance. Our answer is the Mid Compression Socks. Woven on the same medically-approved machines as the rest of our high-performance Oxygen range, this compression running sock boosts venous return and oxygen supply to the leg muscles. Absolutely no compromise is made on comfort, ventilation or weight. The ultra-thin, soft fibres provide an inimitable second-skin feel and maximum breathability through strategically-placed ventilation stripes. Our by-now signature 3D.Dot technology guarantees excellent grip of the foot in the shoe, reducing the risk of skin overheating and blisters. The integrated arch support prevents the fabric from twisting and offers reassuring stability in rocky terrain, while the stretchy fibres allow your toes to expand naturally on impact for instinctive, fluid running. The efficiency of the sock is highlighted by a trendy black and grey design: the stylishly-striped upper mesh allows you to train, race, and maybe even go to the office in featherlight footwear which delivers world-class compression and aeration in a classy package.
