A quarter-height merino sock in a marled yarn, so it reads less like gym kit and more like something you&';d wear on a Tuesday. Half cushion underfoot for the walking part of the day. Merino runs warm when it&';s cold and breathes when it isn&';t, and it can go a few wears between washes without announcing itself. Ribbed arch support, reinforced heel and toe, and a cuff that stays up without pinching. Every product purchased removes one pound of trash from oceans and waterways. Fabric. 65% merino wool, 32% nylon, 3% spandex. Made in China. Sizing. S/M fits women&';s 5-8, men&';s 6-9. M/L fits women&';s 9-12, men&';s 10-13.
