Thanks for this. I have encountered the term "handmade GYW" on a number of occasions as well, which has confused me to no end.
So can we confirm that Enzo's construction is a bona fide handwelt?
ie. carving out the holdfast from the insole itself, and no use of gemming (hand or otherwise).
Actually scratch that, just realised there are a few videos on YouTube showing Bonafe's construction.
