Our new FEEL360 technology is a proprietary fiber treatment that adapts and reacts to the foot to create the freshest and driest comfort experience. By infusing premium twisted yarns with FEEL360, the sock reacts to eliminate odor causing bacteria, adapts to body temperature to keep feet cool, and provides the industry\'s fastest moisture wicking results to keep feet dry. The result is the most durable, best performing, and most comfortable sock on the market. Introducing our Training Uncommon Solids Tab.
