Jason Markk Repel Bundle Shoe Protection Spray and Refill
Skip until ingredient transparency improves, waterproof sprays are classic PFAS vectors.
Jason Markk Repel is a shoe protection spray designed to repel water and stains, but the brand discloses no ingredient list or PFAS composition. Waterproof/stain-resistant coatings commonly use PFAS-based chemistry. Without third-party testing or a brand PFAS statement, this product carries material uncertainty.

What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 32% 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.
