These boots run true true to size. I normally wear US 10.5D boots, and the 10.5D 608s fit quite well.
A packing slip will be provided with the boots that shows the Item Subtotal, Shipping Cost, Sales Tax, and Order Total. In case the boots are to be used for work in a company that helps cover the cost of footwear, the packing slip should qualify as a proper receipt that can be shown to one's employer.
