I have a pair of Shimano MTB shoes SH-MO82 that really stink and It's not from my feet, believe it or not 😉 It's the outside of the shoe that stinks. Smells something like fresh cowshit. In the beginning I just figured it was the new rubber and it would wear off but it hasn't in almost a year, so now I'm getting ready to see what Shimano has to say about it. I also have another pair of Shimano Winter shoes and they don't smell at all even though the rubber on the outside looks pretty much the same.
Is there anybody else out there who has experienced this.
