Timberland Air Raider Shoe & Boot Refresher
Wait for PFAS status from Timberland or independent testing.
Shoe and boot refresher sprays often resist water and stains using compounds that may include PFAS. Timberland shares no ingredient or PFAS facts.

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.
Volatile organic compounds (VOCs) and propellant inhalation
Aerosol sprays release hydrocarbon or fluorocarbon propellants and solvent vapors into air during and shortly after application. Inhalation in poorly ventilated spaces can cause dizziness, headache, and respiratory irritation, particularly in children or individuals with asthma. Risk is manageable with outdoor or well-ventilated use.
Formaldehyde / VOCs
Some aerosol coatings include formaldehyde-releasing preservatives to prevent microbial growth in the liquid phase. Timberland does not disclose preservative chemistry for this product; presence is neither confirmed nor ruled out. Exposure via inhalation during spraying is low but not zero.
Source, ATSDR ↗Silicone or wax coating degradation and microplastic shedding
The refresher creates a thin polymeric film on shoe fabric or leather; over time and with repeated washing or wear, this coating flakes or fragments. If the base contains silicone or synthetic wax, shed particles may persist in soil or water. Timberland does not disclose whether the coating is biodegradable or synthetic-polymer based.
Aerosol canister pressurization and storage hazards
Pressurized aerosol cans can rupture if exposed to heat above 50C (122F), stored in direct sunlight, or physically damaged. Risk of chemical spray release or inhalation injury if canister fails. Storage in cool, dry places away from high-traffic areas is essential, especially in homes with children or pets.
PFAS
Water-resistant textile treatments historically relied on PFAS chemistry (PFOA, PFOS, GenX alternatives). Timberland has not confirmed PFAS-free status for this refresher. Until verified by third-party testing or brand disclosure, presence cannot be ruled out and poses long-term bioaccumulation risk.

What it's made of and why it matters
Timberland Air Raider is an aerosol spray treatment, likely formulated with silicone, wax, or hydrocarbon solvents as the active ingredient, plus propellant gas (typically hydrofluorocarbon or hydrocarbon) and stabilizers. The coating is designed to repel water and restore breathability on leather and textile uppers. Propellant gases and volatile organic compounds (VOCs) are released during spraying and can persist in indoor air; inhalation risk depends entirely on ventilation during application.
The brand's record and disclosure
Timberland has not publicly disclosed the PFAS content or water-resistant chemistry of this product. The brand signed the Apparel Impact Institute's ZDHC Gateway commitment in 2020, signaling intent to reduce hazardous chemicals in manufacturing, but this does not cover finished consumer products like refresher sprays. No recalls or safety violations are on record for this specific product. Timberland does not independently test or certify this refresher for harmful chemicals; third-party lab data is absent from public sources.
How it compares in its category
Aerosol shoe treatments are standard in the footwear category; this product is typical in its delivery method and functional class. Alternatives include brush-applied waxes (lower inhalation risk), water-based sprays (lower VOC but less common for Timberland products), and silicone-free balms. The aerosol format prioritizes convenience over safety transparency, placing it in the middle of the market for respiratory hazard. Many premium footwear brands (e.g., Red Wing, Salomon) either reformulate with plant-based hydrophobes or publish solvent disclosures; Timberland does neither here.
If you buy it
Apply outdoors or in a well-ventilated space (open windows, fan running) to minimize inhalation of propellant and VOCs; do not spray indoors or in enclosed rooms. Hold the can upright, maintain 6-12 inches from the shoe surface, and use short bursts rather than continuous spraying. Allow shoes to dry fully in open air (15-30 minutes) before wearing or storing. Replace the product annually or if the aerosol hisses weakly, indicating propellant loss or potential bacterial/mold growth inside the canister.
