can these be used comfortably with ordinary shoes for short rides?
Yes, they give you that extra platform on these pedals so that you don't have to clip in to use these. These are great for when you want to spend the day riding downhill or if you are in a section of town that has a lot of stop signs.
I used to use an egg beater style clip that had less of a shell as this one and I had a lot of moments when I did not have my clip shoes and just rode without them and it was perfectly fine. So these having more of a shell I can imagine that with these guys you would hardly notice that they are clips under the shell.
