Paraboot Adonis loafers in black smooth leather US 11

I purchased these loafers at a Paraboot boutique in Paris in late 2019 and they have been worn only a few times. Shoes are in excellent condition and have always been stored with shoe trees (not included) in a nonsmoking, child-free home.  The labeled size 10 is UK/EU sizing; these are equivalent to a US size 11.  Current retail price for the closest comparable shoes (same model, slightly different leather) is US $515, and AFAIK Paraboot does not yet ship to the US (their website says coming soon), so obtaining this style is not easy.  Sale includes the original box, shoe bags, and a branded cloth.
