The Smartwool Everyday Margarita Zero Cushion Crew Sock is a soft sock for daily life. Slip each foot into the luxurious blend of Merino wool, nylon, recycled nylon, and elastane for next-to-skin comfort, temperature regulation, and durability. The zero cushion allows for no-bulk inside close-fitting shoes. The built-in stripes shake it up for a bit of fun.
