I really like these shoes.  Ordering shoes on the internet is always dicey. I have very hard to fit feet, so ordered an 11--don't think there was a 10 1/2. The shoes are big but not so big I can't wear them for everyday use. I'll experiment with sizing because otherwise I love these shoes. They have a comfortable lift to the gait, springy and cushiony.  I can fit my orthotics in them. They are attractive. Note, if you are looking for support in addition to cushioning, this is not the shoe for you unless you are willing to buy good orthotics and insert them.
