Dr. Scholl's Performance Sized to Fit Running Insoles
Skip until Dr. Scholl's discloses waterproof coating chemistry.
Running insoles typically use water-resistant foam coatings. Dr. Scholl's does not disclose coating materials or PFAS status, leaving waterproofing chemistry uncertain.

The full breakdown
What it's made of and why it matters
Dr. Scholl's Performance insoles use polyurethane or EVA foam cushioning topped with a durable synthetic topcoat finish designed to repel moisture and extend wear life. The topcoat composition is not publicly disclosed by the brand, which is the primary concern: waterproofing treatments on footwear commonly rely on fluorinated compounds (PFAS) to achieve water resistance, but Dr. Scholl's has not confirmed or denied this. The foam base itself is generally considered chemically stable during normal use, though degradation accelerates with sweat, heat, and prolonged moisture exposure.
The brand's record and disclosure
Dr. Scholl's (Reckitt subsidiary) does not publicly disclose material safety data, PFAS use, or third-party certifications for this product line. The brand has not published statements on fluorinated waterproofing agents or commitments to phase them out. No recalls specific to chemical contamination in this insole line have been documented in FDA or CPSC databases. This silence around coating chemistry is standard for the mass-market insole category but represents a significant transparency gap.
How it compares in its category
Mass-market foam insoles (Superfeet, Powerstep, Spenco) typically do not disclose topcoat chemistry either, making Dr. Scholl's representative of industry norms rather than a leader. Premium or eco-certified alternatives (Vionic with endorsements, or niche brands certified by third parties) more often declare material composition and avoid fluorinated treatments. Dr. Scholl's positions itself on price and availability rather than material transparency, so expectations for disclosure should be low.
If you buy it
Keep insoles dry between uses and allow 24 hours air-drying after wear; moisture traps degradation byproducts against skin. Replace every 6-12 months depending on activity frequency, as foam compression and topcoat wear increase leaching risk and reduce support. Do not machine wash or expose to direct heat above 60°C (140°F), which accelerates topcoat breakdown. If you notice odor, discoloration, or tackiness developing, discard immediately rather than waiting for scheduled replacement.
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.”
Coating leachates (fluorinated or non-fluorinated polymers)
The topcoat finish chemistry is undisclosed. If water-resistant via PFAS, direct foot contact over months could expose skin to slow migration; if polyurethane-based, volatile organic compounds (VOCs) may off-gas, especially in warm, humid conditions inside a shoe.
Polyurethane foam degradation and isocyanate residues
Polyurethane foam manufacturing leaves trace isocyanate residues that can migrate, particularly under moisture and heat (e.g., inside a sweaty shoe). This risk increases as the foam ages and breaks down, typically after 6-12 months of use.
Volatile organic compounds (VOCs) off-gassing
EVA or polyurethane insoles release volatile compounds, especially when new and when exposed to warmth from foot activity. Enclosed shoe environment concentrates these vapors near skin; ventilation and time minimize this, but sensitivity varies by individual.
Bacterial or fungal growth from moisture retention
Foam insoles that are not dried promptly trap sweat and create environments for microbial growth, which is not a chemical hazard but generates metabolic byproducts and odor. This is user-dependent (maintenance failure rather than product defect) but common in humid climates or with high-activity users.
No data on heavy metals or azo dyes in topcoat pigments
Dr. Scholl's does not publicly test or report on heavy-metal content (e.g., cadmium, lead) in topcoat colorants or binding agents. No recalls or published contamination events exist for this product, but lack of testing does not equal absence of risk.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 55% 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.
