Im glad I read the reviews saying the shoes run small. I have size 10 1/2 feet so I go up to size 11 shoe which is 42 european. I ordered size 12/43 and they are still short. I can get away with it with a very thin sock or barefoot. I have been looking for a red and black shoe so Ill keep them. I was also disappointed with the arch. I had hoped it would be more supportive but I was able to use my Orthoheel 3/4 length arch support in them. The shoes appear well constructed and the style is very flattering.
