When it's freezing out - especially if it's overcast, or raining, or windy - a good pair of shoecovers are pretty much a must. I've tested the Castelli Diluvio shoecovers for an entire winter, and am happy to say they've held up while sylin'.

I've always gravitated to Castelli products - they've always been generally good quality, well detailed, and I like the flashy red/white/black design (it matches my bikes and team kit). When selecting shoecovers I thought these looked better than all the comparable options out there, and the price was similar, so the decision was pretty easy.
I wear 42 shoes. I have a pair of X/XL Castelli toe covers that have always fit well, so I went with the X/XL shoecovers as well. These were a little too big and always fall down a bit and bunch up in the back, but I imagine that could've been solved by getting one size smaller.
The stitching has held up well and everything has held together well - and that's after I've really put them through the wringer. A winter season of base training and commuting, and then through early spring cold mornings. The bottoms have gotten a bit torn up, but I think that's expected if you walk around with them on. But certainly no more than other shoecovers I've had.
ARE THEY WARM?
Yes, they are warm - though in sub freezing weather my toes still will start to get numb. When it dips down that low I either supplement these with toe covers or an additional aero shoe cover on top. They do well in warmer conditions, and my feet don't start sweating in them until into the 40s. So overall I'd say they work as I'd expect them too, but nothing amazing.
These are pretty good with keeping water out, but when it's pouring and everything is soaked, they will also get soaked. That said, they do a pretty good job of keeping the cold out in those conditions. And when it's raining that hard and it's less than 40 degrees out, shouldn't you be on the trainer anyway?
Yes, I'd recommend these. I like the syling (the main reason I picked them), but they also function well. There's nothing spectacular about them, but I think they are a solid choice. Bottom line, I'm not looking for new shoe covers any time soon!
