Keep in mind Nike shoes run a half size smaller than most. If you don't know your size in Nike, definitely go up half a size. Nike frees are my favorite shoe. These are a cross trainer instead of the regular running shoe so they are more narrow.
My husband is difficult to fit. He has wide and very thick feet. These shoes fit great, support him well and aids his walking. Just wish they came in black in his size.
These shoes provide great support if you are flat footed. Very comfortable. I am a size 12 with nikes but with these shoes and the lunar tr 1's are a little smaller than usual. I recommend ordering a 1/2 size bigger.
