Ive used them for a couple of weeks now and do not regret the purchase. In preparation for my vacation to Orlando (Disney and universal) I was on the search for the perfect athletic sandals to keep my feet dry, have good support and not rub anywhere. Stylish and comfortable. * * * Edit: Reason for edit : Tribit claims 20 hours of battery life -- but that is a flat out lie! A little smudged as its not packaged. It can be challenging to keep her happy, but on a hunch, I decided to pick up a pair of these pajamas to brighten her day. It does not tighten to a point where it will stop, just to a point where you feel some resistance. The range is quite good. One will show a little footprint on the footbed. I would say these might be better for a thinner foot.
