These are beautiful when they first arrive and nice enough to wear with a dress.  After a time the straps stretch and they get dirty easily so become great for around the house. They still look nicer than flip flops for a trip to the beach or the store. They are very comfortable; I wear them in lieu of slippers at home.
Downside is that there is not much grip on the sole and what there is wears quickly making them death defyingly slippery on waxed or wet floors/sidewalks. Still I bought 2 more pair when the first ones started looking a bit decrepit.
If you are a half size go lower rather than higher - I have tried both.
