I ordered size 13EE of this shoe. It did not seem true-to-size to me. I normally try to have about a thumb-width of space between my big toe and the end of the shoe.  This shoe had about one and a half thumb-widths of space. It is longer than four other size 13 shoes I compared it to: Mizuno Wave Renegade 3, Saucony Guide 3, Brooks Trance, and New Balance 856.  I will be returning the shoe, but I am likely to re-order a half size smaller. It felt pretty good and seemed likely to be a good running shoe. One of my reasons for buying this model is that I have very flat feet and the arches in most shoes are too high for me.  The pair I tried on did have a very low arch and I'm pretty sure it will feel good when I start running in a smaller size. I recommend buying a pair at a local store where you can make sure you get the right fit.  If you like the shoe, you can order subsequent pairs at the better online price.  I am looking forward to getting the correct size so that I can test this shoe on a run.
