Are shoe waterproofing sprays non-toxic?

None of the 15 shoe waterproofing sprays we graded clear our screen. Non-toxic is not a defined or regulated term, so what we can tell you is what our graders recorded. Beyond PFAS, the hazards found or left unruled-out on shoe waterproofing sprays in this category are VOCs and off-gassing, microplastics, undisclosed fragrance, undisclosed ingredients.

Why NikWax Fabric & Leather Duo-Pack grades highest here, and why that is not a pass

Every grade on this page is one sum. A category starts from a baseline, each disclosed material or coating adds risk points, and each thing the brand or a third party has published takes them away. Below is that sum for the winner, then for 2 products it beats, so you can see exactly where the 25 points between the top and the bottom of this shoe waterproofing sprays ranking come from. Nothing in this category reaches our 70 point pass mark, so this is the shape of the field rather than a recommendation.

What to watch for in shoe waterproofing sprays

Beyond the PFAS grade, these are the things our graders recorded on the 15 shoe waterproofing sprays in this category. We assess from materials, brand statements and published research. We do not lab-test.

  • VOCs and off-gassing

    Volatile compounds that evaporate out of a material at room temperature, which is what a new product smell is.

    Found on 7 of these shoe waterproofing sprays. Plausible but unconfirmed on 8 more, meaning nobody has ruled it out. EPA

  • Microplastics

    Plastic fragments small enough to shed from a product into food, water or air without anyone seeing it.

    Plausible but unconfirmed on 4 more, meaning nobody has ruled it out. EPA

  • Undisclosed fragrance

    A single word on a label that can stand for dozens of undeclared ingredients, protected as trade secret.

    Plausible but unconfirmed on 1 more, meaning nobody has ruled it out. FDA

  • Undisclosed ingredients

    Not a chemical. The absence of one, where we found no statement from the brand about what it uses.

    Found on 2 of these shoe waterproofing sprays. FTC

The shoe waterproofing sprays we would skip

Lowest scoring in this category, worst first, with the reason.

How to read these scores. PFAS Authority is a scoring system, not a laboratory. We do not test products ourselves. Each grade is a model-based assessment built from published ingredient lists, materials, certifications, brand disclosures, recalls and third-party lab results where they exist. Read the full rubric to see exactly what adds and removes points.

What we check on shoe waterproofing sprays

  • Confirmed PFAS, PTFE or fluoropolymer content, which is the heaviest penalty we apply.
  • Stain, water or grease resistant treatments, which usually mean fluorinated chemistry.
  • Whether the brand discloses what is in the product, or stays silent behind a “clean” claim.
  • Independent lab results and certifications where they exist.
