Smart Fit System
Our technically advanced SmartFit system is our PHD in foot movement and behavior. We have researched and designed a combination of elastic arches for support and stability, ankle braces to prevent slipping, and a contoured flex zone to keep bunching at a minimum. These anatomical design details give these socks the ability to move seamlessly with your foot.
TO ensure Smartwool gets as much wool against your skin as possible. They created WOW (Wool-on Wool) Technology. Here they have replaced some of the nylon in the high impact zones of the sock, (heel and forefoot) with some more Merino wool.
