Designed to keep feet cool, dry and comfortable throughout activity, these lightweight, breathable men's Storm Bloc Trainer Socks are made from our Performance Polyester blend, which actively works to resist, and then wick moisture away. The construction of every sock in this triple pack of Storm Bloc Trainer Socks places protection and support where it's required, with terry loop cushioning to absorb impact, and integrated arch support to reduce fatigue, and help stability on varied terrains that put added stress on the feet to deliver maximum protection and comfort.
