I was so disappointed when I tried this show on.  Probably the most comfortable athletic shoe I've ever worn and it almost fit...almost.  I usually wear a 13+ so I ordered a 14 (the largest size in this model) but even that was just a tiny bit too short. I've kept and worn shoes this much too small before but I walk 4 miles per day and wanted that little bit of toe-room
Bummer...but if you can order them larger than you wear, I promise you won't be disappointed.
