GM Trail Sky Run

Sock designed for ultratrails and the great altitude differences of mountain running. The elasticised, wrap-around structure provides excellent stability on the foot and in the shoe. It is made of microfibre for excellent thermoregulation. The toe and heel are made of NanoGLIDE®, for its anti-blister function. Ergonomically constructed with asymmetrical toe box for the right and left foot, cushioning and protection in the toe, heel and insole. The high cuff protects the ankle without squeezing it. The moderate graduated compression facilitates venous return and contributes to a faster exchange of oxygenated blood, reducing the feeling of heaviness.
