I have always been reluctant to buy shoes on-line but I decided to give it a try. Thanks to all of you wonderful Amazon customers who took the time to describe your experience and give your honest feedback!  I have a very high arch and instep and many shoes will not fit over my foot. Also, in some shoes I wear one size and in some another size.  I took a chance and bought what is usually my "regular size".  They fit perfectly. With the adjustable straps, my instep problems are solved. But most of all, when I put them on the first time, my instant response was "Ahhhhhhh" - they are so very comfortable right out of the box. No "breaking in" at all.  They have become by favorite summer shoes and while some sandals are only for casual wear, these are nice enough to wear anywhere.  Delivery was on time as advertised and they even included easy return instructions and pre-paid return label.  Fortunately, I didn't have to use it.
