H-e-l-p! how to get rid of stubborn foul smell in a pair of 50s eng. boots

[Pa12]

Pa 12/D97x7 thanks for your inputs. Pa12- Indeed there are cheap versions flooding the market today but the outsole brand detail (on mine) are your tell-tale signs of age if no tag/brand info is present. Im pretty sure they are atleast 50's, what im not sure about is if they are older.

Quite possible. As I said engineer boots have been around a looooong time. Hard to find nice new ones these days without spending big bucks. They’ve all gone to steel toe or big clunky treaded soles. Not my thing. But even the “cheap “0nes I used to get were pretty nice in comparison. I noticed yours are leather soles with caps. Do you think the caps are original or added on?
