They breathe surprisingly well in summer too, despite having tiny vents and looking like they'd be plastic hot tubs.

In fact, I just swapped pedals on my Ironman so I can use the Fizik shoes in cold weather. The Ironman had Look delta pedals that I used with a nice pair of Scott Road Pro shoes that are built more like sandals than shoes -- minimal uppers, just enough to hold the shoe together between the generous airy mesh panels, including large vents in the soles. But impossible to get comfy with in winter, even with thicker socks and shoe covers.

Only problem I've had with the Powerstrap is some fraying of the Velcro. I'll touch it up with some superglue or a bit of heat to create a melt-knot. Otherwise the uppers and soles have been very durable and easy to clean.

And the Powerstraps lay flatter with my tight fitting shoe covers. My Scott shoes have buckles and the shoe cover compresses the buckle into my foot, making it uncomfortable after awhile. I don't know if that's an issue with boa closures.
