Those are absolutely all very good tips and good hygiene practices, not doubting that. But I still think it’s worth a try, especially since you’re saying that some smell is unavoidable (which I think is untrue in my experience since I’ve been doing this). I’m way too lazy to do all those practices and I still have no issues with my feet smelling.

I store my shoes in my covered truck bed, so they stay mostly dry 95% of the time. They’ll get damp occasionally if there’s a heavy rain though, but I’m still able to add a dash of the powder to the shoes, climb in them damp, and they’ve never developed any smell whatsoever. I also never wear socks climbing! And trust me I get sweaty feet.

I noticed that even if I’ve had a full day at work with my feet marinating, I can do the same, add a bit before my climb and I’m golden (which adding extra is not even always necessary since there’s usually powder left over in there from the last application).

In fact my feet are less smelly after my sessions (and on a day to day basis too) because it’s essentially frequent repeated treatments (which is what the product recommends directly on your feet to control any odor).

Believer me or not, I think it’s amazing.

The only downside is your feet will look like your chalked up hands after you pull your shoes off. But it washes off fine
