Castelli Invisibile Women's Sock, Without an ankle cuff, this sock is virtually invisible under your cycling shoes. However, it still provides comfort, keeps your feet dry, and offers arch support. If you want a sockless tan but also value cycling performance, then this is the sock for you.

Key features:

• Meryl® Skinlife yarns with bacteriostatic silver ions
• Diaphanous web mesh on top of foot
• Midfoot support band
• No ankle cuff for a practically invisible look
• Heel tab to prevent rubbing on the back of the cycling shoe
