Castelli only gives the "Rosso Corsa" designation to its best gear. The Castelli Rosso 9 Socks earns this due to their Meryl Skinlife antibacterial material, a high-density elastic midfoot support band and a 9 cm cuff. The material and highly breathable open mesh top design will keep feet dry through the duration of most rides and the flat lock seam will go unnoticed. Basically becoming a second skin inside your shoe.
