Not great but I would probably buy again since there are not a lot of choices (especially in bigger sizes).
Ive been bike commuting year-round for 7 years in Seattle (75 min each way). So not new to this stuff, but these are my first waterproof bike shoes. Prior to this I did Sidi Dominators with Neoprene covers. In serious rain, I use plastic bags over my shoe, under my cover. A winning combo but a pain to put on.
I wear size 13 in normal shoes and my size 48 Dominators with DeFeet Blaze socks (year-round) is a perfect fit. The Diablos were huge when I got them. I was worried I should have bought size 47 and spent several weekends searching for thicker socks to help make up the difference. Having used these for the last six weeks Im glad I got size 48. Theyre still bigger than Id like but Im getting used to them (with my old socks). My overall sense is that these remind me of cowboy boots, not shoes.
The other problem with the fit is the ankle part. It doesnt go up high enough so sometimes my tights pop loose over the top (even though I use a pant cuff strap on both legs). Additionally the ankle part doesnt completely seal around the leg. I have average size legs in the ankle and there is always a gap. Then when your foot bends during the pedal stroke, the gap opens and closes as you cycle. It should be about 2 to 3 inches taller. Having said that, theres a weird sensation having something tugging against your ankle (compared to the Dominators), though after several weeks you stop noticing that.
These are not waterproof in real rain. In normal Seattle showers, theyre good but in a downpour (somewhat rare to me) water is getting in and I dont know how. I suspected it was dripping down the gap in the ankle I mentioned above but Im not sure if thats really the source. My toes have been very wet and my ankles felt quite dry. In the worst downpour I felt water sloshing around in my toes. When I was done with the ride, water didnt pour out of the shoe, but my socks were soaked. On the plus side, my feet didnt get cold on those downpour days (all above 42F).
To begin with, my extremities (hands and feet) tend to run colder than other people I think. Two things I learned First, my DeFeet Blaze socks are not warm. Second, the Diablos arent warm. On my maiden voyage with the Diablos it was 36F and my toes were as numb as usual. I would say the Diablos are quite a bit cooler than my old Dominator with Neoprene covers. Over the last 6 weeks Ive tried a few different combos of socks and my Costco brand wool socks were fairly warm (except too tall). I havent found a better cycling sock for warmth yet.
