These are great for keeping your feet worm.

I went on a ride the weekend before I purchased these and my feet were very cold by the end of the ride. After purchasing these and using them the next week, all I could say at the end of the ride was wow. These were definitely worth the money and made an immediate difference.

Very Happy

Worn these a few times in cooler temps and they have worked well and kept my feet warm. Make sure you fit them over the cleats correctly as the neoprene will tear.

Adequate for rain but less so for freezing below
by TaulPaul

I purchased the 2xl to wear over my Sidi Avast 48 winter road shoes. They work fine for rain & wind and I like the reflective accents, especially lining the rear zipper. The toe panel seems ok so far (a couple of months in). The stretchiness is ok, but EVERY TIME I put these on, the neoprene on the outside of the shoe is getting caught on the buckle of the shoe and it's a pain to work my fingers in under the stretched neoprene and get it released so the cover sits properly. I don't think the 3mm neoprene is thick enough, my feet are definitely colder than in my older BikeTiresDirect-branded winter shoe covers. Those must be 4mm or 5mm thick and are what I wanted but couldn't find this year. These are adequate for our Seattle-area rain, but as temperatures dropped down into the mid-30's and lower, I was wishing for a slightly thicker cover. The Diluvio C definitely looks nicer, but I'm a daily winter bicycle commuter - I'll take function over form nearly every time. Worth the mid-$30's price I paid, wouldn't have been happy if I'd paid more.

This was purchased to replacem 3 yr old Castelli Estremo booties. This is a much better product and more appropriate for Portland weather.

Decent shoecover
by Anonymous

Very warm shoecovers, but not recommended if there will be walking involved. I used them on a gravel ride twice now and the front bottom is starting to tear. My fault really. They are more intended for road shoes. Seems like they should beef up that area so that you can ride them in all conditions and terrain.

Easy to put on a take off. Good looking.
