Every climber has the same problem- smelly and sweaty feet, making your climbing shoes the same! This is the perfect cure! The boot bananas can easily be slid into your rock climbing shoes after use and absorb moisture to prevent bad odours. These boot deodorisers are better to be used at the start of your climbing shoes life to optimise results, but will still stop your existing shoes from getting worse. If your shoes are exceptionally sweaty, shake the bananas to release a fine mist powder to speed up the drying process. Replace your Boot Bananas when they start to go brown, due to the saturation of moisture.
