So I just purchased these and all in all they are great.  The foot bed is very soft and comfortable but firm enough to offer a bit of support.  What I didn't care for is how small/short the adjustment band is.  I do have somewhat tall arches but I had to adjust this so far out that it almost didn't make it the Velcro  base.  Secondly, due to it being so tight it rubbed across the top of my foot a bit.  So, if you have really flat or low rising feet these might be perfect for you.  They're also very classy looking for a pair of thongs.
