Made from ZQ-certified Merino wool, Smart Wool's Run Targeted Cushion Mid Crew socks naturally resist odors, regulate temperature, and offer breathability. And their comfort only goes up from there, because they’re designed with feel-good features like the Virtually Seamless™ toe and the 4 Degree™ elite fit system for a dialed-in fit. Plus, Indestructawool™ technology helps these run socks go the distance. For better, more comfortable runs, be sure to choose the gear that works.
