I really like these sandals!  As a woman with very wide feet AND a very high arch and instep, I have a terribly difficult time finding shoes that fit comfortably and also have the arch support I need... All without rubbing on scars on my feet from previous foot surgeries.  I have to wear orthotics in all my shoes, but it's pretty much impossible to find sandals that will accommodate them AND prevent them from moving around and even slipping out the back. (Besides, it looks ridiculous to have them showing in sandals!).  So very happy to have discovered Vionics (thanks to my podiatrist's recommendation).  I have a pair of Vionic slippers I love as well.  I've discovered that often, men's shoes tend to run a bit wider than women's, which is why I ordered these - and they are awesome!

These sandals are the best and most comfortable and supportive I've ever worn.
The only thing I don't love about them is the rubber sole... It tends to make the bottoms of my feet sweat, as they can't "breathe" at all.  That is why 4 stars instead of five.  (I'd choose 4 and a half if I could.)  I'm going to try to find some kind of fabric insole product (or maybe that adhesive moleskin)  that I can stick on bottom... Will update here if/when I do, as I think that would make them perfect!
