40 some years ago when I was working as an arborist, I wore my very expensive Wesco climbing boots ( decades later now priced at $395/pair) to help muck out the family barn. For whatever reason the stitching attaching the midsole to the welt gave way. Fortunately home was less than 100 yards away. As the uppers were pretty badly scarred by that time I decided not to have them resoled. Knowing what I know now, it probably would have been worth the money to have them resoled.
The other boot was fine: the sole survivor.
