Shoe Gear Water Repellent Aerosol Spray
Skip until brand discloses waterproofing chemistry or gains verification.
Water repellent aerosol sprays often use PFAS-based Teflon-family coating for durability. This brand provides no PFAS disclosure, ingredient list, or third-party testing, making it impossible to assess risk.

Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
Vague safety claims only
Uses vague language ("eco-friendly", "clean") without a specific PFAS statement.
The full breakdown
What it's made of and why it matters
Shoe Gear Water Repellent Aerosol Spray's exact polymer formulation is not publicly disclosed, making it impossible to verify whether it contains PFAS or other hazardous water-repellent compounds. Most aerosol waterproofing sprays for textiles/footwear rely on fluorocarbon or hydrocarbon polymer coatings; the fluorocarbon variants carry high PFAS risk. Without ingredient labeling or technical documentation, you cannot distinguish between safer hydrocarbon alternatives and fluorinated polymers.
The brand's record and disclosure
Waterproofing Company has maintained silence on the chemical composition of this product and has not published any third-party certifications (OEKO-TEX, bluesign, or PFAS-free claims). No public recalls or safety controversies are on record, but absence of disclosure is itself a red flag in a product category where PFAS contamination is industry-standard. The brand's lack of transparency suggests either use of conventional fluorocarbon chemistry or unwillingness to invest in safer alternatives.
How it compares in its category
Most aerosol waterproofing sprays fall into two camps: older fluorocarbon-based products (high PFAS risk) and newer hydrocarbon or silicone-based alternatives (lower hazard profile). Without disclosure, Shoe Gear cannot be positioned on this spectrum. Brands like Nikwax and ReviveX publicly disclose solvent chemistry and offer PFAS-free options; Waterproofing Company's silence places it at a competitive disadvantage and signals potential use of legacy formulations.
If you buy it
Apply only in well-ventilated outdoor spaces or with respiratory protection, as aerosol inhalation of fluorocarbon polymers may pose respiratory irritation risk. Allow treated footwear to cure fully (typically 24 hours) before wearing. Do not spray near food, water sources, or living areas. Reapply annually or after heavy wear; discontinue use immediately if you develop coughing, wheezing, or respiratory symptoms and seek medical advice.
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.”
Volatile organic compounds (VOCs) / respiratory irritants in aerosol formulation
Aerosol waterproofing sprays typically contain propellants and solvent carriers (often hydrofluoroalkanes or volatile hydrocarbons) that can irritate airways, especially in enclosed spaces or during prolonged application. Specific solvent identity is not disclosed for this product.
Inhalation exposure to polymer micro-particles
Aerosol spray delivery generates fine mist particles of the waterproofing polymer coating. If the polymer is fluorocarbon-based, inhalation poses known respiratory risk; if silicone or hydrocarbon-based, risk is lower but still present during and immediately after application.
Formaldehyde or other resin cross-linkers
No evidence that this product contains formaldehyde-releasing resins, but textile finishing sprays sometimes do; absence of ingredient disclosure means this cannot be ruled out entirely.
Accumulation of waterproofing coating on fabric over repeated applications
With each reapplication, polymer layers build up on shoe material. This can reduce breathability, trap moisture, and create a stiff, uncomfortable fit. Buildup also increases the total amount of coating-bound chemicals in contact with skin.
Dermal contact sensitization from fragrance or additives
No ingredient label is available to assess fragrance or chemical additives that might cause allergic contact dermatitis; product formulation remains opaque.
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.
