Hi All - I have time to add one post here, before jumping on a plane to Italy to work. Unfortunately will not be able to participate during this run. For sizing, I converted the sizes and marked the stock to coincide with my Dundalk boot fittings. The boots are NOT marked correctly, as this factory didn't understand my translations. I have redone the fittings, and they will go out correctly, but I can't change the sole stamps. Again, fittings here = Dundalk fittings, if you can connect the dots from previous massdrop offerings. Or on our site (Dundalk is on 42 last). As Hikers, they will fit shorter in the toes and slightly wider than a dress last/fitting (length the same but toes will end up being closer to the toe box since this last is rounder...as is correct for a functional Hiker). The linings are 100% lambswool - including the footbed - and the uppers are a good full grain calf (although I don't know the exact weight...probably around 1.8mm). Hope that helps, and thanks for looking in!
