Boot Bananas are shoe sweat absorbers and deodorisers made from natural ingredients. They keep footwear fresh and dry thanks to absorbent minerals and fragrant essential oils with anti-bacterial properties. The "banana skin" is made from cotton, allowing the minerals to absorb the moisture while making it inhospitable for bacteria and odours. Boot bananas are made from natural bamboo charcoal, sodium bicarbonate, zeolite and natural fragrances (lavender, lemon, patchouli and tea-tree oil) all wrapped in a 100% cotton banana skin. As your Boot Bananas soak up moisture they will slowly turn brown, just like a "ripe" banana. When they have turned fully brown, they are saturated and it's time to change them.
