Boot Bananas will put a stop to stinky shoes. Moisture absorbing, fragrant foot deodorisers, ideal for rock climbing shoes or any other whiffy footwear. Simply put your bananas into your shoes after a hard workout to prevent smelling out your gym bag or car. Bamboo charcoal eliminates odours by absorbing moisture and releasing dry air. Lavender oil has relaxing properties and leaves a fresh odour.
