Ralyn Aquatec Waterproof Shoe Protector
Skip this product due to unknown waterproof coating chemicals.
This shoe protector spray has no disclosed waterproofing chemistry. Waterproof treatments usually rely on fluorochemicals, but Gecko won't confirm either way.

What Ralyn Aquatec Waterproof Shoe Protector is made of, ingredients and materials
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.
What’s concerning
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
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
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.

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.
What’s reassuring
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 metals
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.

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.
