I usually wear a 10.5D I ordered 11 as there was no 10.5 which also doesn't match other reviews where the shoes ran small. They fit perfectly. I wear 10-10.5 everywhere and 11 fits better than my Nikes and is more comfortable than my Brooks. I needed something with comfort and padding for work and it gives me exactly what I need without lacking in support. I would definitely buy them again when my current ones wear out.
