This style of sandals is wonderful!  They are so comfortable and stylish. I have 3 pairs, in different colors.  People compliment me on them all the time. They run true to size, which is rare to find in shoes these days.  The adjustable strap allows for some variation if you need more or less room.  I also like the arch support and cushioned heel.  I've been paying for very expensive orthotic type shoes the past few years, but these are just as good, if not BETTER-- and a fraction of the price!
