The shoes that I received are much smaller than the size that I ordered.  This was my fourth pair of Moab Ventilators.  All of them were size twelve.  Although the size indicated on the shoes and the box said "12" They were more like a 10.5 or 11.  I didn't hear back when I submitted a question about an exchange.

I ended up giving them to my friend who wears an 11.  I bought a replacement pair (size 12) at a local store (only $4 more) and they fit properly.  They are excellent shoes.  I use them as every day shoes, not as hikers.  They seem to be better quality than the comparable Hi-Tec shoes.
