Our new Running II sock is a variation on our Original sock. The Running II sock is still a flat knit no cushion midweight sock designed for all running activities. This new style also has a bit more Lycra® and a Stabilizer ZoneTM for a snug but not tight fit. Features the perfect combination of moisture management and friction-free control. This sock provides all the protection you need without shoe sizing issues. Perfect for the Running sock user who would like just a slightly snugger fit.
