Afaik they only faked the suede model that is one of the first releases. The tag is the blue/white stripe on that model.
IIRC it was stock config- if I were given a do-over I would try japanese tight fit but as you mentioned the sizing difference is almost negligible. I think the hide is very thick and with the quilting and zipper hardware its a true moto jacket. I expected something less substantial, which isn't necessarily a bad thing.
Find contact email on visvim.tv - you might need proof of purchase or id tags i dont remember the latest. They give you an address you ship at your expense and voila 4 months later your boots are resoled and you pay to ship them back.
IMO I think if the cut was strictly lemaire people wouldn't understand so its some pseudo-hybrid between the two. I can't afford to size up else everything would be huge, but if I get to return 90% of the stuff my wallet is happy.
