The Castelli Diluvio 16 overshoes are warm and a touch taller than usual, and they do a good job of keeping water out.
These are made from 3mm thick neoprene that's stretchy enough to pull over your shoes really easily. The neoprene wraps around the sides of your feet and round to the soles with just holes for your cleat and heel, so you get good insulation here.
The Diluvio 16s are just a little bit taller than most other overshoes so you get a little extra coverage. I got out the Road.cc ruler (we have just the one) and measured them at about 8cm above the ankle – enough to notice, not so much that it looks ridiculous.
A YKK waterproof zip up the back takes care of closure. The flap behind it extends over the top too, like a chinguard at the top of a jersey, so the zip can't snag your Lycra. Reflective material on either side of the zip helps get you noticed at night – and it's more conspicuous than a similar amount of reflective on a jersey, say, because of the movement of your feet.
A version of these with a Velcro closure – which we reviewed last year - remains in the Castelli range.
Go riding in heavy rain in any overshoes like this and your feet will get wet sooner or later – the water soaks in via your tights or gets in at the bottom, it's sneaky like that – but the extra height, the fact that the seam down the middle is thermosealed as well as stitched, and the waterproof zip mean that the Diluvio 16s keep the worst of it out. The main point is that any water that does get inside does so slowly so your feet don't get freezing in the process.
When it's not raining, these provide enough insulation for most winter conditions without being too bulky. Castelli give temperature ranges for all their products (everyone else should follow suit) and they go with -5°C to 12°C here. It hasn't been sub-zero around these parts yet this winter, but judging by the Diluvios I had last year, I'd say that's reasonable.
Oh, and they've got a gert big scorpion on the side and that's clearly badass.

Size tested: 2XL
Tell us what the product is for, and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?
Castelli say, "The 3mm Neoprene fabric will stand up to the wettest and coldest winter riding conditions. All seams are thermosealed for complete water protection, with cleat and heel areas open for stability while walking. The stretchy material easily pulls over your shoes while a Velcro closure prevents water from running down your leg into the shoecover.
- 16cm cuff
- Reflective detailing on back
- Extra protection – so cozy you'll almost hope for rain"
Apart from the fact that I never hope for rain, that about covers it. As I said in the review, water will always find a way in sooner or later if it's raining hard enough, but these do a great job of minimising that.
Neoprene overshoes start at about £20. Rapha's are £50, Assos's are much more expensive again, although they're having a laugh. £35 for these seems fair enough.

That little extra height, the thermosealed central seam and the waterproof zip.
Tell us what you particularly disliked about the product
Nothing, really. The top looks a little unfinished, I guess. There's no binding around the edge like there is for the cleat and heel holes.
