They're plenty big enough for me. I have a 4 mile ride to school, so I don't bother with clipless on commutes. I'm shoe size 9.5 (US) if that matters. They're at least as comfortable as stock pedals. It is a bit annoying when you start up after a light on the wrong side, but you get used to it and don't think about it after a bit.
Also the metal platform is slippery in the rain.
I'd buy again though, really depends on your case.
