Castelli Rosso Corsa 6 Sock

Italian flair for your feet.

Rosso Corsa is Castelli’s designation for its best gear, and the Rosso Corsa 6 Sock is the shortest in the Italian brand's superlative line. The Rossa Corsa is woven with Meryl Skinlife fibers to fight odors, and the top of the foot is an open mesh to keep you as cool as possible. In the arch, Castelli wove a high-density band into the sock that holds the sock firmly in place while you ride. The sock also has a flat seam and the cuff is folded over to prevent slipping.

  • A competition cycling sock for happy feet
  • Meryl Skinlife fibers keep you cool and fresh
  • Mesh top for added ventilation
  • High-density arch band adds support and reduces slipping
  • A flat seam and folded cuff ensure fit at either end

Runs a little small for XXL

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: Runs small
  • Size Bought: XXL

Good quality. Comfy for summer.

High quality

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

Great feel from these socks. My feet stay cool. Material and stitching are done well. Only negative is the red dye runs from sweat. No problem washing them. Color did not fade.

Excellent look & feel

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: L/XL

these socks are great, very thin and height is perfect

Great socks

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

Got the XXL for my size 12/46 feet. Good fit. More material in the heels, toes, ankles. Less across the top. Feels great. Height is just right.

Light and fit well, not good quality

  • Fit: True to size

After the first use these seemed pretty good. Felt light, breathable and fit well. My disappointment came after washing them (maybe I shouldn't have put them on the washing machine). The started to come off on the inside. Maybe is not too bad and I'm pretty sure I'll keep using them, but I had very high expectations from Castelli

Great Socks!

These are my favorite socks, they are very thin and breathable. I use them for everything from biking, running, hiking and even wear them at work. They don't have much cushioning, but that is another thing I like about them; they are low profile and keep my feet cool.

Favorite socks

  • Fit: True to size
  • Size Bought: XXL

Bought XXL for my 12.5 foot. Great fit. Very light and breathable. Looks very cool. Easily the best athletic socks I've ever bought. I can't fit into Castelli clothes, but their socks serve me very well.

can I ask what kit you do use? - i am a similar build / height and struggle to get kit that fit my thighs - cheers Mark

Blazingly fast footcoverings

  • Fit: True to size
  • Size Bought: XL

Without a doubt the most amazing socks I've ever worn. I've moved from Cat 4 to Cat 1 in only 5 weeks, my power-to-weight ration went to 5.8:1, and my thinning hair is looking fuller and more luxurious. The only knock is that I believe I may possibly be in violation of Rule #27 of the Velominati ( http://www.velominati.com/the-rules/ ) governing sock height. I can only give 4 stars, as they are not carbon fiber, and the red is not precisely the same red as on my Rossa shorts.

Biking For Days

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: S/M

These socks are very soft, confortable if I could afford them I would where them as my everyday. I have been biking in them for down hill and cross country and in clipless and five tens. They never fail me. By the way the coloring of the fluorescent yellow socks is awesome! I have had two pairs for about 6 months now and they still look brand new! May get the longer version of the sock very soon. If so stay tuned for another review!

P.S. I wear a size 8 in women's and th S/M fits perfectly!

Hey Nicole! Welcome to the Backcountry Community!

Great Socks!!

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

Own a few pairs so i had to get a pair of red ones.Very good quality!!

great socks

  • Familiarity: I've used it several times

i recently gave a pair of these a try and I'm very happy I did. I have subsequently got more to qualify for free shipping. Wow I'm writing a review on socks ha.

Good Socks

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

Fairly thin but allow for good breathability. Quite stretchy as well compared to other wool socks.

Love these socks!

  • Familiarity: I've used it several times

I never imagined socks could improve a ride so much. I bought one pair of these on sale. Liked them so much I bought two more. I am size 9.5-10 U.S. and the L/XL is a perfect fit. Very comfortable for riding in warm/hot weather. If it's cool/cold get the wool socks.

Lovin the socks!

  • Familiarity: I've used it several times

Great lightweight sock that give a nice snug fit to your feet. No bunching at the toes. If you are on the fence on size, order the smaller size.

You want them!

  • Familiarity: I've used it several times

I bought a pair of Castelli Garmin Team socks and said in my review I would buy them all over again even in plain white. Well, here they are and available in white, black and red. They fit great, have a porous panel on top of foot for cooling, and wick moisture away from skin very nicely. These are the 6 cm which is the height cuff I like-don't like the 'footies' and don't like the high tops. I wear a 45 shoe and the L/XL fits perfectly.

You want them!

Great sock

  • Familiarity: I've used it several times

Thin, well fitting sock. Size is accurate from recommendations. Haven't used for extended period so I can't comment on longevity but they are great so far.

Buy them

    They fit well (15.5 - 11 US Athletic) and feel good.

    Perfect warm weather sock

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

    Gorgeous sock, lightweight and breathers well. Ideal for warmer weather.

    Fits just great

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    I gave this socks as a gift for my father and he loved them, he said they fit perfectly, they are very soft and on summer they avoid his feet to get too warm.
