PowerStep Pinnacle Orthotic Insoles
Minimal PFAS risk. Standard orthotics rarely treated with fluorinated coatings.
PowerStep Pinnacle insoles use foam and fabric materials without inherent PFAS concerns. No waterproof or stain-resistant coatings typical of PFAS-treated products documented.

The full breakdown
What it's made of and why it matters
PowerStep Pinnacle insoles use closed-cell foam (typically EVA or polyurethane) bonded to fabric top covers, a standard construction for arch-support orthotics. The foam provides cushioning and structure without requiring chemical treatments common in performance textiles. Fabric components are typically polyester or cotton blends; the binding adhesives are the primary chemical exposure point, though orthodic formulations rarely use volatile adhesive systems. This material class does not require flame retardants or antimicrobial coatings that trigger safety concerns in apparel.
The brand's record and disclosure
Pinnacle (PowerStep parent company) maintains minimal public disclosure on material sourcing or chemical composition for insole products; no OSHA or EPA violations are on record. The brand has not published certifications (e.g., GREENGUARD, Cradle to Cradle) specific to insoles. No product recalls or health complaints have been documented for this line. Silence on PFAS and additives is typical for the orthotic insole category, not unusual for the brand.
How it compares in its category
Foam-based orthotics are the industry standard and carry lower chemical risk than gel-infused or silicone alternatives, which require more complex formulations. PowerStep Pinnacle sits in the mid-market bracket; premium brands (e.g., Superfeet, Powerstep Pro) often provide slightly more transparent material specs but face no major safety advantages. Budget orthotics and custom-molded versions show comparable hazard profiles. This product's construction is typical and represents no outlier risk.
If you buy it
Replace insoles every 12-18 months as foam compresses; monitor for fabric separation or adhesive breakdown, signs the binding has degraded. Store in cool, dry conditions away from direct heat or sunlight to slow foam oxidation. No special cleaning protocol needed; hand wash with mild soap if soiled. Do not use heat guns or washers to clean, as moisture and heat can accelerate adhesive failure and foam 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.”
Adhesive volatiles (formaldehyde / other VOCs)
Foam-to-fabric bonding in insoles may use low-VOC or water-based adhesives, but adhesive composition is not disclosed by Pinnacle. Off-gassing risk is typically minimal in insoles due to brief manufacturing off-gassing and indoor use in shoes; no threshold exceedances are documented.
Azo dyes in fabric
Top-cover fabrics in orthotics are rarely subjected to the azo dye restrictions applied to apparel in contact with skin, as insoles sit inside shoes. No brand-specific reports of azo dye use in PowerStep products; standard textile suppliers for insoles typically avoid banned azo compounds.
Formaldehyde-releasing resins
Orthotics do not typically use urea-formaldehyde resins common in hardwood or particleboard. PowerStep's foam and fabric composite avoids this hazard class entirely.
Heavy metals in pigments or colorants
Insole fabric dyes are generally not subject to cadmium or lead restrictions specific to ceramics or coated cookware. No heavy metal contamination has been reported in this product category or brand.
Antimony in polyester
If top-cover fabric is polyester (likely), trace antimony catalyst residue from polymerization may be present at typical levels (< 0.5 mg/kg). Skin contact via insoles is minimal risk; no extraction or ingestion pathway exists. Industry standard does not flag this as a health concern in footwear textiles.
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.
