Shoe Protector Spray, Rain & Stain Waterproof Spray 8.45 OZ Nano Protectant for Sneaker, Nubuck, Canvas, Suede Shoes 1 Pack
Skip, waterproof spray with undisclosed nano-coating and no PFAS transparency.
This shoe protector spray uses a proprietary 'nano protectant' formula with no public disclosure of chemistry or PFAS status. Waterproofing and stain-resistance sprays are historically high-risk for PFAS (especially C6/C8 Teflon-family coating), and vague marketing terms like 'nano coating' obscure the actual ingredients.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
