I ordered these in men's 6.5/women's 8, which is my true size.  It was a struggle to get my feet all the way into the shoes because the upper is so tight.  If I order a half size up though, my heels will slip out of the back.  So, while the length of the shoe is true, the space between the insole and upper only allows for a pancake thin foot!  If these are the only shoes someone wears, it's probably because their grossly misshapen feet won't fit into normal shoes!

That being said, I did receive my shipment quickly.  The sizing on this page was very misleading, but I looked at shoezoo's website to make sure the size I ordered would be the size I received (they were the vendor that came up when I chose my size from the drop down).  I only wish they offered free returns.
