thanks for those details, I wasn't aware of the problems caused by glue. But still, I would call this goodyear shoes rather than a goodwear-welted shoes as there is no welt, and so the problem of punching new holes each time you resole the shoes remains.Spoke with the maker.
Ok so as per the video basically the whole thing is protected so that there is no glue used which keeps the upper in-tact. Which you can see from the video. It isn't exactly like a bog standard goodyear procedure but a goodyear machine
So normally with sneakers glue is used as well and it doesn't mean sneakers can't be re-soled but you risk tearing the upper apart.
When re-soling these that is never an issue. That is the advantage of the construction.
So all that is required is the stitches come off on the outsole and then there isnt any glue there soa new sole just goes on and is stitched on in the same place.
