The design of the 2 in trekking socks is inspired by the exploration of the requirements for the feet during long walks. The two-layer system helps to prevent the fabric or seams of shoes from forming bubbles or rubbing the skin. The two layers ensure your feet stay comfortable while helping absorb shock on impact. 3D structures increase protection at the most exposed areas such as the shin or Achilles tendon. The 2IN trekking socks are ideal for summer hikes: the areas with increased breathability of the inner layers combined with Cool Air Flow technology ensure a constant flow of air that keeps your feet dry and at the right temperature.
