I'm not a fan of the look of crocs, but I did get a pair of the Croc flip flops. Those are really comfy! And they look like normal flipflops. Nothing odd about them, in my opinion.
I also bought a pair of croc Mary Janes for the cooler weather to wear with jeans. Wore those last time in WDW (2 weeks ago, cool January weather) and I loved them. They look a little less "croc-ky", especially with long pants.
I teach aerobics, and I have enough tennies/gym shoes/hi performance foot gear to choke a horse, and none of them come close to my crocs for all-day wear.
