I've used both these and the Boot Banana Eco and they're both amazing, I have a set for every pair of shoes I have.

They definitely work best if you put them in before any bad smells happen but even if your shoes smell bad already they'll fix that too, in my experience.

They’re soooo smelly in a good way! Y love them so much, they’re always on the side on my bag so muy climbing shoes always smell nice. Also, extra points for looking awesome!

The clever style alone is genius :)
A must for every climber, runner & athlete !!

Thank you for making these whimsical & necessary items for everyone wearing shoes etc…

These things smell great and keeps my shoes smelling great. I’ve recommended them to so many people I can’t keep track. Between these and a little shoe spray, my shoes actually smell good when otherwise they would be clearing the room like everyone else’s.
