The bucks have around half a size in them at most - therefore pretty true to size imo. If you are on half sizes then I would suggest coming down to the lower full size at most, which is what I did & they fit very well. (standard width)
these don't seem cohesive with the rest of UO's offerings... people willing to spend that much on shoes are likely aware of Mcnairy and his full line. The (typical) UO shopper is looking for inexpensive versions of things they see other places, and quality and construction are probably less important than how a piece looks. I can't see this selling at full price outside of NY LA.
