The SMARTWOOL PHD RUN ULTRA LIGHT Micro Sock is the first choice for runners. It’s made with Indestrucawool technology for added durability. The mesh ventilation provides breathability for those long runs. The Shred Shield technology on the toes provides cushioning to protect from damaging the fabric. Merino Wool is a light fabric that absorbs sweat and keeps you cool. The tab on the heel makes sure the socks stay on snug.
