Supportive and stylish.

When your alarm goes off before sunrise for an all-day ride, reach for your most comfortable long-ride kit and complete it with the Rosso Corsa 13 Sock. Featuring the highest cuff in the Rosso Corsa family, this ultralight sock comes with a supportive mesh weave that won't move around and cause blisters when you're miles from home. Its airy, moisture-wicking fibers consistently draw moisture away from your skin to keep your entire foot dry from your warm up spin to the last climb of the day.

  • Tackle your longest rides with dry, comfortable feet
  • Meryl Skinlife fibers resist odor while they wick
  • Midfoot support strap aims to ward off arch fatigue

The new version....

  • Familiarity: I've used it once or twice and have initial impressions

...of Castelli's classic Rosso Corsa socks features improved looks: More subtle/streamlined​/integrated graphics at the top of the cuff.

Otherwise, they are the same great Rosso Corsa socks. Perfect height (13 cm), thin, well ventilated foot. Made in Italy.
