JOHN W.wrote a review of Castelli Rosso Corsa 13 Sock on August 6, 2016
I like a really thin sock. Living in the south, I find that thicker socks give me hot spots. Was glad to see Castelli introduce a cool summer sock taller than their 9's. Could do w/o all the Rosso Corsa branding but they do the job really well so I can deal.
