I received the shoes yesterday and I am wearing them today.  They fit true to size.  I wear 10.5 size.  I am also very flat-footed (overpronate) and the heel of the shoe helps to keep my ankle from rolling inward.  along with the shoe arch supports, my foot feels pretty good.  I have speed walked in them but I have not ran in them yet. They are light-weighted, which is good for me since I am a distance jog/walker.
