"A PERENNIAL FAVORITE
Coming into its 7th year in the Castelli line, the Rosso Corsa continues to be our best-selling sock because it’s that good. The Meryl Skinlife® yarns feature bacterio- static silver ions to keep your feet and shoes fresh, the cuff cradles your ankle just right, and the diaphanous web construction keeps your feet cool. Try a pair and you’ll un- derstand why we obsess about a sock. Available in 6cm, 9cm and über cool 13cm pro-style versions."
