Just back from a trip to New Orleans, AJ's seemed to be the popular shoe over there. I know little about them and other than the classic AJ1 I never really liked the look of them either but I took a few pics anyway as they seem well regarded on here. Lots of NMD's on display but no one wearing them.
Seeing as this is primarily a cycling forum I should mention there does seem to be a small fixed gear scene, more ladies than men from what I saw. The bike of choice for the everyday rider is a cruiser style frame with single speed and coaster brake, which suits the flat terrain and hot humid weather perfectly.
A word on the Nike chalapuka shoes too, really comfy all day and no sweaty end result that you get with rifts or roches.
