My 2 y/o actually cries when I take these off his feet!!  He completely loves these and only complains if his little toe gets stuck in one of the openings while putting them on.  I'm a little disappointed in the smell... I was hoping that these would *somehow* be different than every other pair of similar shoes that I've ever owned.  They're not.  His feet are stinky and he's only been wearing them for 3 weeks.
