The Socks: Teko Eco Merino

Teko bills its foot cozies as the best socks for the planet, and with its new line of merino performance socks—with fiber straight from the sustainable Tasmanian sheep farm of Downie-Dungrove—they may be right on the money. Ranging from thin, ankle-high models that slip into running and cycling shoes to thicker, higher socks for hiking, these eco-sustainable socks use non-toxic dyes, turning your feet into earth-friendly ambassadors wherever they go. $14 and up; www.tekosocks.com
