Excellent fit thanks to adjustable headband/height. Size 12 is perfect for my size 12 foot and the width can be adjusted to accommodate changes in swelling. I ordered shoes for the first time and they fit true to size. The only thing I don't like is that the part that goes beyond the heel is soft and flexible. If the shoe is "fitted", it will flap up when you put it on, so you have to pull it up with your finger or use a shoehorn.
