Fit Flops are GREAT!! I think they are much more supportive then Teva Mush. I get mine @ Macy's.

My mom swears by Fit Flops and she has terrible heel spurs, she says they saved her life. She made sure to buy the Disney ones when we were there!
I wore my Fit Flop around AK and DHS today. My right foot has a couple nasty blisters. I think I just need to get them broken in, though. For support they were just as comfy as sneakers!
I'm kind of a flip flop snob too-- refuse to wear those cheapo plastic Old Navys.
