I normally love Fitflops - I have two other pairs and I wear them to death.  These - though comfortable to wear for walking - will give you teeny tiny slices on your ankles (and feet) when those stupid sequins come in contact with your skin.  I wore them walking at Disneyland recently and had to go get Disney band-aids to cover the slices in order to keep going.  If I had brought another pair of sandals, I would've left these for housekeeping.

With plenty of styles to choose from, do yourself a favor and get a different style.
