These seem to run true to size, if not slightly large. I normally wear a size 10.5D, and these boots fit me quite well. These will fit someone who normally wears a size 10.5D, 10D, and possibly someone who normally wears a size 9.5D after putting in thick footbeds.
However, if the shoe box is requested, I'll see if it will fit inside the flat rate box after folding it. This item is in the category "Clothing, Shoes & Accessories\Men\Men's Shoes\Boots". The seller is "brushwoodbootstore" and is located in this country: US. This item can be shipped worldwide.
