This is part of the famous Dansko fit. Think of the perfect fit as a "pinkie width" between your heel and the back of the shoe. This space at the back of the heel allows your foot to move naturally when walking and keeps your toes from hitting the front of the shoe. The Dansko Professional is sized according to European (EU) whole size standards.
