All socks are the same, right? But what if a sock could make a shoe better? S-PHYRE believes it can. By looking at the shoe/sock interface and applying Shimano Linkage Effect approach, S-PHYRE socks combine thermoregulation, comfort, ankle roll stability, and heel slip-resistance with an extra-tall cuff that’s guaranteed not to droop. Asymmetrical structural weaving of proprietary fabrics provides guiderails for proper foot alignment through the entire 360-degree crank rotation. And you thought a sock was just a sock. By the way, they look great with S-PHYRE shoes, and work even better too.
