Hi
I have a few hiking boots (Scarpa, Lomer, Boreal) and mountain running shoes (Merell, Salomon) which have a persistent smell even after repeated washings. Mirazyme was of no help for them, so I would like to try the next thing people says it works, which is ozone “therapy”.
The problem is all these shoes have Vibram rubber sole or something equivalent (thick, solid rubber). From some sources online I learned that in general rubber doesn’t stand well to ozone, which causes cracking even in small concentrations.

So it depends on how the rubber is treated for ozone resistance. My question is, does someone have experience with ozone odour removing for hiking boots, especially those with Vibram rubber ?
