Go ahead and pamper your feet out there on the rough terrain, they'll thank you for it!; Features a lightweight, blister-free hiking sock with anti-compression loops for resilient cushioning. Sculpted pads protect the foot while 360 degrees of venting cools it. Extra padding on ankle bones and achilles tendon anchor heels down to heel counter and ankle pockets of footwear. Sock remains cool and light regardless of extra padding because of large vented areas where padding is not needed. Consists of 44% nylon, 27% merino wool, 27% polypropylene, 2% elastane. Machine wash cold tumble dry low. Available in a 3 pair pack.
