Description

More sophisticated than your diet.

Stay ahead of rising sock cuff trends with Castelli's Rosso Corsa 9 Sock. It's got one of the higher cuffs in the Rosso Corsa line, but it's still within the realm of tradition that the industry is destined to return to after the current too-tall trend dies out. Height aside, the sock's ultralight blend of Meryl Skinlife yarns wicks moisture fastidiously throughout your ride, warding off chafing and blisters whether you're on-course or pedaling just to enjoy the views.

  • Ultralight sock for your hottest summer rides
  • Meryl Skinlife yarns resist odor as they wick
  • Stretchy yarns hold their shape to prevent blisters
  • Traditional cuff height is neither too tall nor too short

great sock

  • Familiarity: I've put it through the wringer
  • Fit: True to size

what can I say, they are socks, but oh how comfy they feel on a hot summer day.

So comfortable

  • Familiarity: I've used it several times
  • Fit: True to size

and light weight. They feel great on my skin. I picked up another pair. These are an up grade over defeet. Though i am not sure if they will hold up as well since the fabric seems thinner.

Classic road sock

    This appears to be the new '17 version. New colors and streamlined detail at the top of the cuff. Same great socks.

    These are a very thin sock. Tight around the shin (so they stay up). Highly ventilated at the top of the foot.

    Meryl Skinlife textile is silver infused so it inhibits bacteria (and thus sock stink).

    In very hot weather (>90°), I prefer Castelli's Free 9s.

    Sizing: In my experience, the official Castelli size chart is best. Euro shoe size >45 =XXL.
