Find the right shoe size The Alpha model fits normally, we recommend that you choose your usual size. If in doubt between two sizes, be sure to choose the smaller one! Note: we slip an additional pair of thin insoles into each package. This slides under the insole and saves a half size in case the shoes are too big. Maintaining your Zeta We advise you to waterproof your shoes to fight against the rain and prevent stains. Concerning maintenance, a sponge or a soft cloth with soapy water will suffice to preserve them. Preferably, we recommend using natural soap to avoid chemical substances. To give them a boost of whiteness and shine, we recommend that you use the clay cream, a natural cleaner that allows you to clean recycled shoes without damaging them. Don't wait until your sneakers are dirty to take care of them. Like anything, the dirtier it is, the harder it is to catch up. Knowing that vegetable matter does not really like chemicals, it is therefore strongly advised not to use products intended for animal leather, or even classic stain removers.
