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.
