PowerStep Pinnacle Low Insoles
Lower concern insole, but verify materials with brand if PFAS-sensitive.
PowerStep Pinnacle insoles use foam and fabric with no known PFAS-heavy treatments. Brand makes no PFAS disclosures. Standard insole materials carry lower risk than coated apparel.

The full breakdown
What it's made of and why it matters
PowerStep Pinnacle Low insoles use a layered construction of foam cushioning, fabric covering, and leather components. Foam cushioning (typically polyurethane or EVA) is a stable material with minimal leaching risk at body temperature and indoor humidity. Leather tanning and fabric dyes are the main chemical exposure points, though leather is generally well-regulated for heavy metals in consumer markets. The fabric layer's dye chemistry and any flame retardants or finishes are not publicly disclosed by the brand.
The brand's record and disclosure
PowerStep does not publicly disclose material certifications, chemical test results, or PFAS policies on their website or product documentation. The brand has no documented recalls or public safety controversies on record. They do not advertise third-party certifications (e.g., OEKO-TEX, Leather Working Group) for their insole products. This silence makes independent verification difficult, but absence of reported incidents suggests no acute safety crisis.
How it compares in its category
Insoles as a category carry lower chemical risk than footwear uppers because they do not involve synthetic polymers (polyurethane, PVC) that are common sources of phthalates or antimony. Leather-topped insoles like this are more chemically transparent than fabric-only or gel-core alternatives, which may use undisclosed synthetic resins or polymers. Many competing insole brands (Superfeet, Spenco, Dr. Scholl's) similarly lack public chemical disclosure, so PowerStep is neither above nor below category norm.
If you buy it
Store insoles in a cool, dry environment away from direct heat or prolonged sunlight, as foam can degrade and off-gas volatile compounds at high temperatures. Replace every 6-12 months depending on use intensity, as foam compression reduces cushioning and structural integrity. Hand wash with mild soap and water if needed; do not machine wash or expose to solvents. Monitor for any skin irritation; if rash or odor develops, discontinue use and contact the brand for material information.
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.”
Azo dyes in fabric covering
Fabric layer composition and dye chemistry are not disclosed by PowerStep. Azo dyes are used in many textiles but restricted in EU and Japan; US regulation is weaker. No specific reports link PowerStep insoles to azo dye exposure, but without material certification, risk cannot be ruled out.
Heavy metals in leather tanning
Leather components in consumer footwear products are generally subject to implicit supply-chain compliance with heavy metal limits in major markets. No recalls or complaints involving lead or cadmium in PowerStep insoles have been documented. Leather Working Group certification is absent, so independent verification of tanning chemistry is not available.
Formaldehyde or formaldehyde-releasing resins in foam or adhesives
Polyurethane foam and fabric-to-foam adhesives can contain formaldehyde or releasers as cross-linking agents. PowerStep does not provide off-gassing data or VOC certifications. Risk is low for body-worn products at room temperature, but sensitive individuals or high-heat storage may encounter detectable odors.
Flame retardants in fabric layer
Insoles are not regulated as flammable textiles in the US, so flame retardant additives are not mandatory. No public disclosure or complaint record suggests their presence in PowerStep products, but formulation is not independently verified.
Skin sensitization from dyes or leather finishing chemicals
Individuals with sensitive skin or metal allergies (e.g., chromium from tanning) may experience contact dermatitis. PowerStep provides no ingredient list or allergen warnings. Risk varies by individual and is not specific to this brand but applies to all leather-and-fabric insoles without full disclosure.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% 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.
