I typically wear a 39 in EU sizes. However, I bought a pair of Alegria Feliz shoes last October in that size, and my feet slip around quite a bit. I got a 38 in these - in US sizes I wear an 8.5C/D (aka wide). I expected them to be a bit tight over the ball of my foot (wide feet, duh) and indeed they were, but my foot doesn't slosh back and forth in these like my Feliz pair. I have the Golden Girl color in suede, so I was able to spray a bit of water where the upper pinched my foot, and stretch it at home with the water and a tapered bottle. They fit perfectly now. I'm very satisfied with the workmanship on my shoes, and the soles are wonderfully comfortable. However, I gave 4 stars instead of 5 because they don't make wides! Get with it, Alegria!
