Boot Bananas, Shoe Deodourisers. Originally designed to rid the world/your kit bag, of the over powering stench that emanates from your climbing shoes. Packed full of moisture-absorbent minerals & lovely fragrant essential oils that possess antibacterial properties, these guys will suck up the sweat & kill the bacteria that causes odours. They are also great at drying out & de-funk; wet boots, running shoes & any other smelly bits of footwear. These Bananas are stuffed with naturally absorbent bamboo charcoal, sodium bicarbonate & zeolite. Which is doused with lavender, lemon, patchouli & tea-tree essential oils. All nicely packaged into 100% cotton banana shaped sleeves. Not only do they look like bananas, they act like them too. Over time the Boot Bananas will start to ripen (change colour), when they are fully saturated the bananas will turn brown just like the real thing. this takes about 6 mouths of good use. To prolong the life of your Boot Bananas allow them to dry in the sun or next to a radiator before storing back in the re-sealable bag. Do not store damp......it wont be pretty.
