Among the plethora of Tour de France paraphenalia strewn about the DeFeet Clubhouse are small metal figurines first made popular in the post WWII era editions of the great race. “Where's Yellow” brings those collector pieces to a classic sock design.

The DeFeet EVO Air high performance cycling sock was created as an evolution of the Aireator®, the World's first open mesh-weave sock. EVO Air ushers in an entirely new level of customization possible in socks with a flat knit cuff and fully customizable design that is made for print to align with top tier cycling kits. The EVO Air now brings this remarkable technology to every rider in a sock that offers more performance than ever.
