I typically wear an 11 (44) in American ( Cole Hahn, RedWing) shoes and a 10 (43) in Italian (Gucci, Prada) shoes. I bought the 11 (44) and they fit perfect. Now on tot he shoe's look and feel. I can't wait to wear these on an upcoming trip to Miami and this summer. I love the look and the photos don't do full justice to their style and look of craftsmanship and material. I was also pleasantly surprised they came with 2 different styles of laces and have an elastic band so they can be worn with no lace. Clever re-styling and blend of spectator and saddle Oxford with a modern twist.
