From what I understand, Its going to be some small changes to the uppers. No piping on the topline, slightly different seaming techniques, with the addition of a poron pad and either a butyl sole or a dainite depending on the style. Basically they're updated enough to warrant a new name designation.
Thanks for the information. It looked ever so slightly different, for the better, in pictures but the difference was small (and the new pictures are better). I was hoping for a different last. I think the MacNeil on the same last as the Leeds would be a definite winner.
