The Castelli Rosso Corsa 6 is the shortest version of the Rosso Corsa sock. It's the Rossa Corsa because that's the designation Castelli uses for their best gear. They 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 6 Sock comes in three colors: Black, Red, and White. The toes, heels, mid-foot band, and cuff logos are in contrasting colors. Sizes are S/M, L/XL, and 2XL.
Excellent product - well made. I wear US shoe-size 10 or 10.5. From previous comments I went with size S/M and it turned out a perfect fit. During training rides above 80 F, these socks ventilate the mid-sole region. Previously I was wearing thin running socks from Nike, etc. where heat build-up was a problem. Castelli products have good form and style designed for cycling. So far I have two pairs of these and wear a Castelli fingerless glove with minimal padding - so far I'm getting great results.
VERY VERY GOOD SOCK!!! I have 3 pair and all have lasted YEARS. Only other sock that compares is the Swiftwick sock, but the Castelli's look better!! PI and Sockguy and others won't last and don't fit any were near as well as these!! Buy em you'll be glad you did!!
I got them on sale off course and they are worth every penny. The quality of the materials cant be any better, my feet stayed dry and comfortable on a 60 mile ride, What more can I say other than it also looks very nice, Its Castelli. 5 STarZZZZZ
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.
This is my first pair of socks from Castelli and they are awesome. Great quality and fit plus they look really cool. Just too bad they are $$$.
Nice fit, nice fabric. The 6 is a good length. Shoe size 43, 10.5, sock size l/xl. Just Right.
Best socks on the market! I like the mid-foot band on the foot for added support.
Great sock. Pretty thin. Great for warm weather riding.
I'm not sure who's to blame but the socks I ordered were clearly used. There was a gash down the heel side, defined sweat stains on the soles, and severe damage to the elastic. What's worse is that I paid more for the shipping than the actual sock cost me, then an additional $7 to send it back, so in the end a single pair of socks cost me about $25. Realcyclist lost some points in my book on this one.
