If you're looking for a dependable run sock to help you churn out those miles, this one might just fit the bill. Indestructawool and Shred Shield technologies increase the sock's durability, while the 4 Degree elite fit system, women's specific fit, Virtually Seamless toe, and breathable mesh zones increase its comfort. Add to that its Merino wool construction, which aids in odor resistance and temperature regulation, and the Women's Run Zero Cushion Ankle sock is a "shoo-in" to be one of your favorites.
