Btw goodyear welt is famous but most welted boots can be resoled, and ultimately even some non-welted but it's usually notworth it for those.

For example, stitchdown welted construction can be resoled just as easily or even easier (no messing with cork). There's also the Norwegian "Storm Welt" that's a more waterproof version f welted boots. There's the fancier Blake stitch for more dressy shoes, and other types and hybrids...
