These boots run large. I normally wear US 10.5D boots, and I've found that 10D Iron Rangers often fit quite well as is. 

These 10D 8111s should fit someone who normally wears 10.5D boots, and possibly someone who normally wears a slightly smaller sized boot after putting in footbeds. 

It's worth mentioning these boots are Factory Seconds that were purchased directly from the Red Wing Shoes Headquarters store in Red Wing Minnesota, but they don't seem to have any considerable flaws. Red Wing's Factory Seconds are shoes originally sold at discounted price for having some flaw, or flaws. Such flaws can range from something minor, such as a welt that has triple stitching in a spot that should have double, to something major, such as a distinct color difference between the shoes. Factory Seconds can be identified by a small hole that's punched into each of the tongues. Though Factory Seconds may have flaws that are aesthetic, their built-in quality or durability shouldn't be affected by such flaws. 

These boots were thoroughly cleaned and conditioned prior to being posted on eBay, and were treated almost exclusively with Red Wing Shoes branded care products. The only non-Red Wing product used on the boots was the UV Shoe Sanitizer made by PediFix to help ensure that the interior of the boots were properly disinfected. 

Posted below is a link to various Red Wing Shoes care products I have available. If anything else is purchased within a few hours of buying the boots, I’ll be able to combine the orders and ship everything together. If the link doesn’t work, search for ‘Misc care’ on my store page and the listing should pop up.
