Rosso Corsa is the designation Castelli uses for their best gear. The Rosso Corsa socks are their best, and since Italians value style you can rest assured that they come in several cuff lengths. The Rosso Corsa 13 comes in a 13cm cuff, the longest Castelli makes.

The Rossa Corsa are woven with Meryl Skinlife antibacterial fibers. The sock is thus wicking, will feel dry pretty much in just about every circumstance save a rainstorm. The top of the foot is a diaphanous web, ultra-thin and extremely breathable. In the middle of the foot, the arch area, there is a high-density band woven in. You won't notice any difference in thickness, but you will feel like the sock is becoming one with your foot rather than sliding around between your foot and your shoe. The toe has a flat seam for comfort and the cuff at the top is folded over to keep the sock from slipping.

The Castelli Rosso Corsa 13 Sock comes in two colors: Black and White. The toes, heels, mid-foot band, and cuff logos are in contrasting colors. Sizes are S/M, L/XL, and 2XL.

  • Meryl Skinlife antimicrobial fabric
  • 13-centimeter cuff length
  • High-density mid-foot band
  • Flat stitching along toe

Euro cool, nice for late season

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: L/XL

I like a higher sock for late season riding. I'm glad I checked the other reviews in terms of sizing. I wear a 10.5 US or 44 Euro shoe, I purchased a L/XL in these. I have a short pair of Castelli socks that are XL/XXL that fit similar. Well made, I'd love to see a bit more padding however. Made like a summer sock but in a taller version.

They are just comfortable, I can not stress this enough, I have wore regular padded athletic socks ( Puma ) and they just do not hold a candle to these, and they are not as padded, how don't even know how Castelli was able to do it, they are light on the areas that need to be and they have more fabric in the ankle area, helps a ton when is a bit cold out.

One of my favorites

  • Familiarity: I've put it through the wringer

Top of the line socks for sure. The thin webbing helps keep your foot cool in the summer and doesn't bunch up under your shoe. After about ten washes they still look great. I bought the white pair.


    I love Castelli socks. They're the best in the business. Great fit, quality, ventilation, looks. These are made in Italy.

    The fit chart is correct. If your cycling shoe is size 45 or larger, I would definitely go with the XXL.

    Favorite socks

      My new favorite socks. They are tall enough to look PRO even on my super long legs and size 47 feet. They stay put without bunching in the toe. They don't chafe in the rain. They are a summer sock -- nice and thin around the foot with no half-cocked attempts at "compression". If you prefer the Swiftwick thickness, these may not be for you.

      Perfect socks

        Excellent socks. These Castelli Rosso's are just the right length that I like. They are longer than most bike socks around. They feel comfortable in my shoes and are both thin and sweat wicking as you need.

        Killer socks man!

          These are by far my favorites socks to date. Tall and comfy and with that PRO look how can you go wrong? Perfect for those warmer rides, so you don't come home with a swamp foot.
