Shoe Chalk Climbing Shoe Cleaner Blocks are a natural, dissolvable deep-clean treatment for climbing shoes, sold as a pack of two. Drop a block in, add warm water, and the foaming solution lifts sweat, dirt, odour and grime from deep inside the shoe.

Made in the UK from natural, chemical-free ingredients, Shoe Chalk is scented with tea tree and peppermint essential oils and produced using a process that needs significantly less water and leaves a lower carbon footprint than conventional cleaners. It's a low-waste way to keep well-used shoes hygienic and help them last longer. Choose it when a freshener isn't cutting it and the shoes need a proper reset.
