I gave these to my husband as an early Christmas gift since we were headed out of town to do some sight seeing.  He didn't complain once (and often new shoes on a trip can be a bad experience).  The shoe purchased was his normal size 10.5, and it fit just fine.  He said the shoe felt "light" and he didn't have any "rubbing" anywhere on his foot.  In fact, he just purchased a second pair two days ago in this exact shoe (different color).  My husband is a coach and needs a flexible shoe to be able to perform in many areas-he loves these shoes.
