Ralyn Aquatec Waterproof Shoe Protector
Skip. Unknown waterproof coating chemistry poses PFAS risk.
Gecko's shoe protector product lacks material disclosure and PFAS transparency. Waterproof treatments typically rely on fluorochemicals; no reassurance provided.

The full breakdown
What it's made of and why it matters
Ralyn Aquatec is a spray-applied waterproof treatment for shoes, but the manufacturer does not publicly disclose the active waterproofing agent or solvent system. Waterproof coatings on textiles and leather are commonly formulated with either fluorochemical-based compounds (PFAS-containing) or non-fluorinated alternatives like silicone or polyurethane. Without ingredient transparency, the coating chemistry cannot be independently assessed for safety.
The brand's record and disclosure
Gecko does not appear to have published ingredient lists, safety data sheets, or third-party certifications (such as Bluesign, GOTS, or Oeko-Tex) for this product. The company maintains public silence on PFAS use despite growing industry discussion of fluorochemical avoidance. This lack of transparency is a material information gap in a product category where PFAS has historically been standard.
How it compares in its category
Shoe treatment sprays vary widely in waterproofing approach. Competitors like Nikwax use explicitly PFAS-free wax and hydrocarbon formulations, while established brands often use fluorochemical compounds without labeling. Gecko's refusal to disclose places it in an unverifiable middle ground that frustrates informed choice compared to brands with clear certifications or stated PFAS avoidance.
If you buy it
Apply only in well-ventilated outdoor spaces or with respiratory protection; do not use indoors or in enclosed areas. Allow footwear to dry fully (24 hours minimum) before wearing, as freshly coated shoes may off-gas solvents. Reapply only as water-beading diminishes, typically every 6-12 months with normal wear. Avoid skin and eye contact; wash hands thoroughly after use.
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.”
Solvent inhalation and respiratory irritation
Spray-applied coatings typically contain volatile organic compounds (VOCs) as propellants or solvents. Without ingredient disclosure, users cannot identify specific respiratory sensitizers; inhalation during or immediately after application poses risk of coughing, throat irritation, or asthma exacerbation in sensitive individuals.
PFAS in waterproof coating
Fluorochemical water repellents have dominated the shoe treatment market historically. Gecko's silence on whether the coating is fluorinated or fluorine-free, combined with the product's 20/100 PFAS safety grade, suggests non-negligible risk of per- or polyfluoroalkyl compounds in the formulation, which bioaccumulate and persist in the environment.
Skin sensitization and allergic contact dermatitis
Spray coatings can deposit chemicals on skin during application or handling. Without full ingredient transparency, potential allergens or sensitizers in the carrier solvent or resin cannot be ruled out. Users with reactive skin or chemical sensitivities face unknown risk.
Microplastic shedding from coating degradation
No public data exists on whether this product's coating sheds microplastics as it degrades during wear. If the waterproof layer is synthetic polymer-based, long-term weathering could release particles; durability and degradation pathways are undisclosed.
Heavy metal contaminants in pigments or additives
Spray treatment formulations sometimes include colorants or stabilizers that may contain trace metals. Gecko provides no analysis of lead, cadmium, or antimony content; this is a data gap rather than a confirmed hazard, but typical industry testing would rule this out.
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.
