The shoe matched as described. I wear a size m3ns12. So I ordered the m12-13. The foot bed was a little narrow but the strap across was wide enough to give me satisfaction. Very light weight. Feel almost like walking bare footed. They also appear fragile but look very sturdy and enduring. I will put them to the full test as I'm visiting Catalina island this weekend for a wedding anniversary.  I will be taking a back-up similar pair. I never done that before. I will report on their performance upon my return.
