This is a very pretty sandal that also works well to keep the foot properly aligned.
The orthaheel design really does work very well to correct pronation problems and to provide excellent arch support.
Thankfully I noticed the other reviews - this sandal does run quite large.  I am usually a size 8, with a narrow to average width foot.
I ordered a 7 in this sandal and it fits perfectly (note: the straps have velcro and can be tightened to fit).
