Pinnacle · Synthetic Athletic Insoles
PowerStep Pinnacle Maxx Insoles
Lower concern. Insole materials typically PFAS-free, but verify packaging.
PowerStep insoles use foam and cushioning materials with no known PFAS association. Brand makes no PFAS disclosure, and insoles see no waterproofing or stain treatment requiring PFAS.

The full breakdown
What it's made of and why it matters
PowerStep Pinnacle Maxx insoles use EVA foam as the primary cushioning material, combined with polyurethane components and fabric top covers. EVA (ethylene-vinyl acetate) is a closed-cell foam that does not readily leach chemicals into skin under normal wear conditions, making it chemically stable compared to open-cell foams or gel-based inserts. Polyurethane in insole construction is similarly low-risk when cured; the fabric blend top provides moisture management without typical apparel dye or finish concerns since insole textiles face minimal skin contact friction.
The brand's record and disclosure
Pinnacle (PowerStep) does not publish detailed chemical or PFAS transparency statements on publicly available platforms, which is typical for orthopedic insole manufacturers and does not indicate a hidden problem. The brand has no documented recalls or chemical safety controversies on record. As an established podiatric insole supplier, PowerStep products are commonly recommended by foot care professionals, suggesting baseline safety compliance with footwear standards, though third-party certifications (e.g., Oeko-Tex) are not advertised.
How it compares in its category
Orthopedic insoles like PowerStep Pinnacle Maxx sit at the safer end of the footwear accessory spectrum compared to mass-market gel inserts or novelty cushioning products, which sometimes use undisclosed gel polymers or antimicrobial finishes. EVA foam is the industry standard for podiatrist-recommended insoles and carries lower chemical volatility than polyurethane-only or latex-based alternatives. Most competitors in the premium insole category (Superfeet, Vionic, Dr. Scholl's professional lines) use identical or very similar material profiles.
If you buy it
Insoles should be replaced every 12-18 months or when cushioning compresses noticeably, as worn foam loses structural integrity rather than releasing chemicals. Wash fabric tops with mild soap and air-dry; avoid machine washing and heat-drying, which can degrade polyurethane bonds. Store in a cool, dry place away from direct sunlight to slow foam oxidation. Do not use insoles in temperatures above 140F (60C) or in environments with prolonged moisture exposure without drying, as this accelerates material degradation.
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.”
Formaldehyde resins in fabric finishes
Insole fabric blends typically do not undergo formaldehyde-based wrinkle-resistant finishing since they are not apparel; no public data suggests formaldehyde use in PowerStep products.
Azo dyes and colorant toxicity
Insole fabric dyes are minimal exposure vectors due to limited skin contact; restricted azo dyes are not known to be used in standard insole textiles, and no reports exist for this product line.
Antimony in polyester components
If fabric blend contains polyester, catalyst residues (antimony compounds) may be present at trace levels typical of polyester production; human skin contact via insole wear is minimal and absorption is unlikely under normal conditions.
EVA foam degradation and off-gassing
Aged or heat-stressed EVA foam can release volatile organic compounds (VOCs) and acetaldehyde; this risk increases if insoles are stored in hot vehicles or used in high-temperature environments without replacement cycles.
Moisture retention and microbial growth
Insole fabric covers can harbor bacteria and fungi if not dried regularly, particularly in sweaty conditions; this is a hygiene issue rather than chemical toxicity but warrants routine cleaning and air-drying.
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.
