I don't know if I got a defective pair or if all FitFlops smell this toxic but it definitely does NOT smell fit to be in the same unventilated area as any human.  Sickening toxic chemical smell that made me gag and feel like I was going to be sick.  I couldn't even hold my breath long enough to try them on as I didn't want to touch them to my feet or hands.  OMG what was that smell????
