Sof Sole does not disclose active ingredients or PFAS status. Waterproofing treatments commonly use fluorinated compounds; lack of transparency raises concern.

What Sof Sole Waterproof Shoe CVS Pharmacy is made of, ingredients and materials
Sof Sole Waterproof Shoe Protectant lists a proprietary waterproofing formula without public disclosure of active ingredients or solvent carriers. Waterproof sprays and treatments commonly rely on silicone, wax, or fluorocarbon compounds to repel water; the proprietary framing here means the actual chemistry is opaque. Without an ingredient roster, it is impossible to assess whether volatile organic compounds (VOCs), solvents, or fluorinated substances are present in concentrations that pose inhalation or residue concerns.
What’s concerning
Waterproof / stain-resistant treatment
Water-repellent coating treatments have historically used PFAS.
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Volatile organic compounds (VOCs) and solvent inhalation
Waterproof sprays typically contain hydrocarbon or solvent propellants; Sof Sole does not disclose solvent identity or concentration. Inhalation risk depends on ventilation and frequency of use, but is inherent to aerosol formulations.
PFAS
This product received a PFAS safety grade of 40/100 (Poor) and brand is silent on PFAS status. Waterproof sprays are a known PFAS-risk category; absence of PFAS commitment or ingredient list is a significant concern flag.
Source, ATSDR ↗Skin and eye irritation from spray contact
Propellants and undisclosed active ingredients may cause irritation on direct contact. Risk is typical for aerosol products and manageable with proper application technique and ventilation.
Cumulative exposure from repeated application
Users who apply this product frequently over months or years have not been studied for long-term inhalation or dermal effects. Lack of ingredient transparency makes cumulative hazard assessment impossible.
What’s reassuring
Residue on shoe surfaces and secondary contact
No recalls or reports of residue-related skin reactions have been documented for Sof Sole products. Once cured, spray should form an inert barrier; however, durability and degradation pathways are not publicly characterized.
How is this PFAS grade calculated?
The brand's record and disclosure
Sof Sole (SC Johnson subsidiary) has not publicly committed to PFAS-free formulations or published ingredient transparency statements for this product line. The brand does not appear on third-party certifications (e.g., MADE SAFE, Cradle to Cradle) for shoe care products. CVS pharmacy listings lack material safety data sheet (MSDS) or detailed ingredient labeling, which is standard for consumer spray products and suggests either intentional withholding or retailer gatekeeping.
How it compares in its category
Shoe waterproofing sprays are a high-risk category for hidden PFAS because water and oil repellency historically required fluorinated chemistry. Brands such as Scotchgard (also 3M, similarly opaque) have faced PFAS scrutiny; competitors including some eco-focused footwear makers now offer wax or silicone-only formulas with full ingredient lists. Sof Sole's silence on formulation is a relative red flag in a market where disclosure is increasingly standard for premium and eco-conscious alternatives.
If you buy it
Use only outdoors or in well-ventilated spaces to minimize inhalation of propellants and volatile solvents. Apply to clean, dry shoes and allow to cure fully (typically 24 hours) before wearing. Reapply every 3 to 6 months depending on weather exposure and wear. Do not spray near skin, eyes, or pets; do not use on interior shoe linings or moisture-sensitive components (e.g., electronics, delicate glues).
