Ariat Fatbaby Cowboy Boots Cowgirl Boots Ladies’ US 8.5 UK 6.5 - see size note A classic pair of Fatbaby boots. These boots have no size label and have been listed as a U.S. Size 8.5 and a UK 6.5 based on the measurements, the use of a size chart and in reference to how Ariat sizes similar boots. I do not claim that these boots will fit like a UK 6.5 from another maker, or from Ariat. Please check the measurements and make your own judgement. In good overall condition, with general wear and marks in places, as in the photos. The linings are dusty and linty at the bottoms. These boots are freshly polished and ready to wear.
