Beautiful Boots, nice leather, may run slightly large.  I think it is they are just a little wider than I've seen from Ariat in the past.  I can wear these with thick socks and an orthodic and they fit great.  I would try going a half size down but they don't offer it.  So, will keep the slightly large size because it's the logical thing to do.  I got a great deal on sale.  If you are on the fence they are really beautiful in person, the turquoise color is really pretty!!!  The stud detail rocks and the open cut embroidery work is really different!!!  Over all a very unique boot that rocks!!!
