Made from a blend of soft merino wool and elastic yarns, Smartwool's PhD Running Ultra Light Micro socks offer comfort, durability, and stay-in-place reliability. Two different elastic yarns are used in a four-point harness system that keeps the socks in place during long runs; reinforced high-impact areas keep the socks from wearing thin without adding bulk.
