A vegan friendly, non-wool sock for serious runners who like to explore the worlds trails at a faster pace. The Trail Run Ultralight Coolmax Sport has T2 targeted microcushioning combined with extra ventilation for the perfect balance of protection and comfort on the toughest terrain. Coolmax Sport Fusion Technology provides resilient padding, moisture wicking, odour control and outstanding durability on the trails. The Sport Fit gives supportive compression for stability and balance around the ankle and mid foot and the zero debris cuff gives an extended close fit to prevent debris getting in and this means your sock won’t slip down or bunch in your footwear. The natural toe box is wide and un-restrictive, allowing your toes to splay when running and the reinforced seam prevents splits and blow outs when descending.
