Castelli Women's Invisible Sock

The Castelli Women's Invisible Sock is designed with top-of-the-line materials and features.

Q Skin yarns incorporate silver ions for bacteriostatic properties, and a diaphanous web mesh is situated on the top of the foot for stability. Additionally, the midfoot support band ensures a secure fit, while the lack of an ankle cuff makes for a practically invisible look. Heel tabs also help to prevent rubbing on the back of a cycling shoe.
