The vintage style of Smartwool's PhD Slopestyle Vans Checkerboard Medium Sock pairs well with neon jumpsuits, skier and snowboarder feuds, and a whole lot of synth music. Although the style takes a trip back in time, the technology and construction is perfectly up to date. This over-the-calf sock is built with a stretchy merino wool blend for movement and comfort, and outfitted with mesh ventilation, medium cushioning, and a virtually seamless design, helping your comfort levels soar as high as those spread eagles you'll be throwing down.
