Yes the Synxplus Shoe Protectant Spray uses nanotechnology to create an invisible water-repellent film across the shoe surface at a molecular level. Unlike standard waterproofing sprays that sit on top of the material and wear off quickly, the nano-scale polymer bonds to the individual fibres of the shoe material creating a protective barrier that repels moisture and prevents stains from penetrating without altering the appearance, feel or breathability of the shoe. Apply to new or freshly cleaned shoes, allow 24 hours to fully bond and repeat for maximum protection. Reapply when water no longer beads off the surface β this indicates the film has worn and needs refreshing.
