I have at least a half dozen pairs of Naturalizer shoes, all in the same size and width.  I was pretty confident that the sizing on this pair would be the same, but I was wrong this time. I received them and they were very narrow and very snug on my feet.  I've had 2 other pairs of Naturalizers in the same material, and they fit fine.  So not sure what happened this time!  I ended up sending them back and will probably look for a similar pair of Naturalizers in another style.
