Here´s a difficult product to review. I ordered EU 46 and I have normal sized feet, for that size, at least. Ended up returning the item because the openings (the curved dome) that should cover your feet was too small for me. The lengh of the shoe was spot on, and the function probably. The Staff were very helpful with the return request. If you have smaller size feet (below 44) and your feet are narrow, they should fit you nice. If you have a large foot, stay away.
