More sophisticated than your diet.

The Castelli Rosso Corsa 9 is just like the Rosso Corsa 13 and 6, but with a medium-height 9cm cuff. Identical to the other versions, they are woven with Meryl Skinlife antibacterial fibers. The sock is wicking and will help your feet stay dry in almost any circumstance this side of a rainstorm. The top of the foot is an ultra-thin and extremely breathable diaphanous web. In the middle of the foot, the arch area, a high-density band adds support. 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.

  • Cycling socks are a must for any ride longer than 10 minutes
  • Blend of materials for location-specific properties
  • Mid-height cuff keeps tan lines hidden in civilian life

Love these socks. First found these at some used garage sale, ended up loving them keep coming back for more pairs on BC. I honestly use these as all around socks not just for my road biking adventures.

Just Socks

  • Fit: Runs large

Well, they are just socks, but they fit tight, and have enough texture to avoid your shoes slipping around. I like these so much that I wear them with my jeans and white tennis shoes. They just feel right.

They run large. I wear size 9.5 (43) shoes and I went with the small socks. The heel cap is in just the right place. I think that medium would have been too large. I am amazed that ANYTHING Castelli fits large - but there you go. Anyway - buy a few pairs, they are one of the most inexpensive Castelli kit pieces.

Great socks

  • Fit: True to size
  • Size Bought: XL

I really like these socks. True to size (size 10/44 shoe) and don't notice I'm wearing them. I bought additional pairs after wearing them twice. Can't comment on longevity of item as I've only been wearing them this season

Good to the last mile

  • Familiarity: I've used it several times

  • Size Bought: Lg/XL

These are comfortable on all my rides. I ride about 150 - 200 miles per week.

Fits Awesome: Not ideal hot summer sock.

  • Fit: True to size

I selected these socks for the summer months and they are not as cool as a summer sock should be. The foot is as advertised and fits great and is cool. However, the cuff fabric is double-thick all the way down to the shoe which makes it tighter and hotter than a summer sock should be. Great sock just too much cuff material if you ride in 80-90 heat.

Great socks

  • Fit: True to size
  • Size Bought: L/XL

They feel pretty confortable, like you're wearing nothing. I usually order M for everything but for this ones I went with the L and they fit perfectly.

Like you're wearing nothing at all

  • Size Bought: Large/XLarge

Cool, light weight, and durable. I've really enjoyed these socks. I've used them for about 2500 miles of use now and have had no issues. They wash well, no holes, and keep your feet cool even in 90+ degree heat. No complaints. I'm a men's 10.5 and got the L/XL

Thanks for the review Sterling! Super helpful to get this feedback out to the community.

Nice mid length sock

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

I like a mid to high 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 medium height version.

Very good quality

  • Size Bought: L

Very confort and durable. Maintain the elastic and the form after a lot of washs! I bought Large and I use 44EU and it be perfect!

Great Socks. Runs Large

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

Very comfortable, thin sock. I wear a size US 12/12.5 and went with the L/XL instead of the XXL the chart said I should wear. Glad I did because even the L/XL is ALMOST too big. I normally pull my socks really tight but can't with these or the heel will go too far.

Great socks!

  • Familiarity: I've used it several times

A great fitting thin socks that stay in place and do a good job of wicking moisture away from my foot. They are well made with no uncomfortable seams. They look pretty good too.

Keepin you cool

  • Familiarity: I've put it through the wringer

These are super! They're lightweight and airy and it also has a slight bit of compression to the arch of your foot. These are my go to socks for Spring/Summer weather riding!

Wicks Well

  • Familiarity: I've put it through the wringer

These socks rock! They wick well and keep my feet dry and comfortable on long rides. They do exactly what they were designed to do. I like the 9 height. Do your feet a favor get a couple pairs of these.

Awesome sock!

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

These are perfect height. Not to long, not to short. These will transport moisture away from your skin, thus geeping you cooler in the Summer, and warmer during the shoulder seasons. Dry skin will not blister like wet clammy skin does.
