The waterproof Castelli Pioggia 3 Shoe Cover is fleece lined for warmth making it the perfect piece for winter riding. Pioggia translates as rain and this shoe cover is optimised for the rain. The waterproof PU-coated stretch fabric, with fleece lining, is partially tape sealed to stop rain from entering. Combined with a waterproof rear facing zipper and silicone-lined cuff with a cross wrap Velcro strap to seal against shin runoff. While its forte is resisting rain the Pioggia is fleece lined and waterproof, waterproof also means windproof, so the Pioggia is also a very good cold weather shoe cover. The fabric is stretchy and the whole shoe cover has a very close aero profile that's impressive given the amount of protection on offer, this is definitely a fast riding piece and not a commuter shoe cover. The Castelli Pioggia 3 is about as waterproof as you can make a shoe cover whilst remaining close fitting. The combination of PU fabric and fleece lining mean even if damp your feet should remain warm.
