I was hesitant to buy by mail order what for me are pretty expensive shoes. I'm pleased though. No need for arch supports or any other inserts. They are attractive and extremely comfortable. For slip ons, they don't slip! Many of the reviews I read said to buy one half size smaller. Aware of this I followed the Amazon ordering feature that helps you determine what size to order. It asked what size shoe do I normally wear? Size 11 medium width. Does that size normally fit? Yes. OK, it then advised me to order a 10 1/2 size in this shoe. OK, if you say so. Turns out the 10 1/2 fits perfectly and is the only shoe I own that is not size 11.
