Overview

What Is the Castelli Diluvio Pro Shoe Cover?

The Castelli Diluvio Pro Shoe Cover is a neoprene bootie with a thicker neoprene and taller cuff for extra warmth when racing and training in wet, cold weather. Castelli says the Pro name comes from a request from its pro riders for an even warmer bootie. Castelli made the 4mm neoprene fabric 33% thicker and raised the height to cover the lower leg up to just under the calf muscle, enough to cover 20cm socks.

The seams are glued and stitched for added protection from the rain, and the raw-cut top edge helps seal against the skin to keep water out. A water-resistant YKK zipper sits at the back, and reflective print on the heel and side keeps you visible in low-light conditions. Castelli rates it for 32 to 57°F (0 to 14°C) and light rain, and warns that the color may transfer when wet. The Lab carries it in size S/M.
