Hey Alan! Happy springtime in Chicago.
I usually ride in old Shimano MTB shoes, with SPDs attached. Only one of my bikes currently runs SPDs (though I may add a second), but the shoes work well with the rest, which all run with clips and straps. Just be sure to get a pair that don't have thick heels with bulky, knobby tread.
They're nicely stiff (without being uncomfortable) and I can walk in them, which is a plus for most of the riding and commuting that I do. And, if you keep your eyes peeled, they're reasonably priced.
Mine are an older version of this (mine are grey, these are brown). Currently on sale for $29.99 (if you have small feet)!
