I've had Fit Flops before and loved them- amazingly great for your feet, right? This new material, though it's super cute, is unyielding and painful on the top of the feet. I was sure they would have broken in by now, but no go after 5 weeks. Can't return them now, ugh, so I'll keep trying to break them in... grrrr. Advise- by them and try them, but be prepared to return them in the allotted time if they don't fit well- don't rely on breaking this new material in- it's not like the older style of shoe. UPDATE- a year later and still can't wear them. am now trying suede on the inflexible area...
