Why We Like The Rosso Corsa 9 Sock

Castelli's Rosso Corsa Pro 9 Sock features an ultralight blend of Meryl Skinlife yarns that wicks moisture fastidiously throughout your ride, warding off chafing and blisters whether you're on-course or pedaling just to enjoy the views. Cushioning and compression keep our blood moving and our comfort level high, and an asymmetrical construction mirrors our foot shape.

• Castelli's performance cycling sock for discerning riders
• Rep the brand's logo with a minimalist design
• Antimicrobial silver ions reduce odor to stay fresh
• Asymmetrical construction mirrors the shape of the foot
• 200-needle construction increases stretch
