While we absolutely believe in our coating to be able to protect sneakers against a lot of different spills, it does NOT establish an impenetrable forcefield around your sneakers allowing you to reflect laserbeams and roundhouse kick rockets without damaging your sneakers. Meaning fine sand and people stepping on your sneakers will still damage the coating and may push dirt particles through the coating and the fabric of your sneaker. Our coating is proven to protect against accidental spills, rain and wet dirt and also makes it easier to clean your kicks after, as the coating keeps the liquids on the surface.
