Designed for versatility across sports disciplines and casual activities such as leisure hiking, trail running, walking or mountain biking, these men’s and ladies twin packed 1000 Mile Trek Socks are single layer, lightweight knits in a merino wool blend that brings softness and breathability, as well as natural bacteria resistance and moisture wicking properties. Padding is placed at the zones where it’s needed most, reducing bulk and weight without skimping on protection, with cushioned toes and balls of the foot, and extended padding at the heels, stretching up to defend the Achilles tendon. Ventilation zones on the top of the foot increase air flow and built-in arch bracing gives additional support. The flat toe seam protects against blister-causing friction from rubbing and irritation.
