I was just pointing out that there are a variety of styles from very cycling specific looking shoes to very casual affairs that will assume the spd cleat. I would imagine dozens of different shoes in the casual category are available. I haven't done much looking around but I have seen some really cool stuff, sorry don't remember brands. Those Nero's look pretty cool btw.
Doubtful that you wll find many casual shoes using the SPD-SL cleat (if any) though as its mainly a road cleat. You will have better luck going with the old school MTB SPD cleat. And I would personally recommend the Shimano A520 pedal which has a nice big platform if ever using cleatless shoes.
Personally, I would look at all the popular mail order places for images/brand names of the stuff that interested me. Also would run image searches on the popular search engines with terms like spd, casual shoe, recreational, etc.
Once I found a shoe I liked I'd nail down a local store/dealer I could preferably try the shoe on at - I would start by going to the manufactures website and seeing if they have a dealer locator tool. And if not but really wanted the shoe I found would accept that I may have to spend some extra $$ in return shipping costs if the first pair I ordered did not fit just right.
Good luck.
