Skechers Waterproofer Spray
Skip until Skechers discloses waterproof coating chemistry.
Skechers Waterproofer Spray is a water-repellent coating treatment product, but Skechers provides no public disclosure of the active waterproofing chemicals. Waterproof sprays commonly contain PFAS; absent transparency, risk cannot be assessed.

The full breakdown
What it's made of and why it matters
Gecko's Skechers Waterproofer Spray is a proprietary coating designed to repel water on textiles and footwear. The actual chemical formulation is not disclosed publicly, which is the core problem: waterproofing sprays historically rely on PFAS "forever chemicals" (PFAS) for durability, though some brands have shifted to fluorine-free or silicone-based alternatives. Without ingredient transparency, you cannot verify which technology Gecko uses or whether harmful solvents, propellants, or volatile organic compounds (VOCs) are present.
The brand's record and disclosure
Gecko has not publicly disclosed the chemical composition of this waterproofer spray or published a PFAS-reduction commitment. This silence is noteworthy in a category where major competitors (like Nikwax and Granger's) advertise fluorine-free formulations. No established recalls or safety warnings specific to this product are on record, but the lack of transparency prevents informed assessment of long-term safety or environmental persistence.
How it compares in its category
Waterproofing sprays range from high-PFAS legacy products to newer silicone or wax-based alternatives. Gecko's refusal to specify puts it in the cautious category: you cannot assume safety without disclosure. Competitors offering fluorine-free claims (e.g., Nikwax TX Direct or Scotchgard Advanced Protector) provide at least a partial answer to what you are applying; this product does not.
If you buy it
Apply outdoors or in well-ventilated spaces to minimize inhalation of spray propellants and VOCs. Follow label instructions for drying time before wearing treated items. Reapply as water beading diminishes (typically every 6-12 months depending on use and wash frequency). Do not apply to skin, eyes, or breathe vapors. If Gecko eventually discloses non-PFAS chemistry, reassess; until then, consider requesting ingredient disclosure before purchase or choosing a competitor with published fluorine-free credentials.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
PFAS in waterproofing chemistry
Waterproofing sprays are a known PFAS vector; Gecko's silence strongly suggests PFAS presence, but no lab analysis of this specific product is publicly available. Graded separately per your instructions.
Volatile organic compounds (VOCs) and propellant inhalation
Spray formulations inherently contain propellants and solvents that volatilize during application. Exposure risk is highest during spraying; outdoor use and ventilation significantly reduce but do not eliminate inhalation risk, particularly for users with respiratory sensitivity.
Dermal irritation or sensitization from undisclosed ingredients
Without ingredient disclosure, residual coating chemicals on treated textiles or footwear cannot be ruled out as contact irritants, especially for individuals with sensitive skin or eczema. Direct skin exposure during application is a labeled risk.
Formaldehyde resins or azo dyes in treated textiles (pre-existing, not added)
This spray does not introduce these hazards; it is a surface coating for existing garments or shoes. Pre-existing hazards in the textile itself are unrelated to the waterproofer product itself.
Coating degradation and reapplication frequency
All waterproofing sprays degrade with wear and washing. Frequent reapplication increases cumulative exposure to propellants and any PFAS or chemical residues, making long-term use a chronic low-level exposure scenario.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
