MOST COMFORTABLE SHOE I HAVE EVER WARN!!! LOVE THEM> They have ruined me for all other shoes. I usually buy very inexpensive shoes (between $15 and $45), so was nervous about paying $73...but they are beyond worth it!  I wear 9.5 or 10's depending on the shoe. I ordered a 39 (9.5) and think a 40 will fit a little better. They're ok, but a little snug. It's not the worst thing, though, because the material gives. They hug like a very loving glove.
