Powerstep · Synthetic Athletic Insoles & Orthotics
POWERSTEP PULSE E
No PFAS risk data available. Likely lower concern unless treated.
Powerstep Pulse E is an orthotic insole with foam and textile construction. No public PFAS claims or treatment disclosures found; standard foam/textile insoles typically pose lower PFAS concern unless waterproofed.

The full breakdown
What it's made of and why it matters
Powerstep Pulse E insoles combine foam (likely EVA or polyurethane-based) with textile uppers and a supportive arch structure. Foam materials in footwear insoles are generally stable during normal wear and do not experience the heating or liquid exposure that triggers leaching in cookware or food-contact plastics. The textile upper may contain synthetic fibers (polyester or nylon) but are not designed for skin contact at high temperatures or prolonged moisture saturation.
The brand's record and disclosure
Powerstep is a privately held US footwear company with no published certifications (e.g., OEKO-TEX, Bluesign) or public material transparency statements available on the record. The brand has not disclosed chemical testing results or restricted substance lists for this model. No major recalls or chemical contamination incidents are documented in public safety databases for Powerstep footwear products. Silence on PFAS and dye chemistry is typical for the orthotic insole market, where disclosure lags mainstream athletic footwear brands.
How it compares in its category
Powerstep Pulse E sits in the mass-market orthotic insole segment, which generally carries lower chemical scrutiny than premium athletic or fashion footwear. Competitors (Superfeet, Spenco, Aetrex) similarly lack public chemical certifications. Foam-based insoles pose fewer textile dye and antimony-in-polyester risks than full synthetic shoe uppers, since the primary materials are passive support structures rather than dyed fashion textiles.
If you buy it
Insoles do not require special heat precautions or cleaning beyond hand washing; air dry only and avoid direct heat sources. Replace when foam compresses noticeably (typically 12-24 months of daily wear) or if textile separates from the foam base. Store in a cool, dry place to prevent mold growth in the foam. If you have known sensitivities to synthetic textiles or dyes, test on skin contact in a small area first, though full-foot contact risk is low.
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 textile upper
Formaldehyde-based finishing resins can be used in synthetic textiles for wrinkle resistance and dye fixation. No published reports confirm their presence in Powerstep Pulse E uppers. Insole textiles see less rigorous finishing than apparel, so risk is likely lower than finished garments.
Azo dyes in textile coloring
Textile uppers may use azo dyes (carcinogenic aromatic amines) if dyed conventionally. No specific testing data is public for Powerstep products. The small surface area and lack of direct prolonged skin contact (insoles sit inside shoes) limits exposure compared to dyed apparel.
Foam degradation and microparticle shedding
Foam insoles gradually compress and can fragment with extended wear, potentially creating fine particles. These particles are unlikely to be inhaled (they are worn inside footwear) but may accumulate in shoes. Material composition (EVA vs. polyurethane) affects durability; manufacturers do not typically disclose which is used.
Heavy metals in pigments (if colored)
If the textile upper is dyed with pigments, trace heavy metals (cadmium, lead) are theoretically possible but undocumented in this product class. Insole textiles are not regulated as closely as children's clothing or cosmetics, so testing is not routine.
Antimony in polyester textile
Antimony trioxide is used as a catalyst in polyester production and can remain as residual contamination. No recalls or public testing confirm its presence in Powerstep insoles. Direct skin contact is minimal since insoles sit inside footwear over socks.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
