Currex · Synthetic Athletic Insoles & Orthotics
CURREX RUNPRO Insoles Medium / 2X (Men's 13-15)
Lower concern. No known PFAS risk in foam insole materials.
Currex RunPro insoles use foam and elastomer materials not typically treated with PFAS coatings. No brand disclosure on PFAS, but material composition suggests lower risk.

The full breakdown
What it's made of and why it matters
Currex RunPro insoles are constructed from EVA (ethylene-vinyl acetate) foam and polyurethane foam, both common cushioning materials in footwear and orthotics. These foams are chosen for impact absorption and arch support rather than chemical risk mitigation. EVA and polyurethane do not typically leach toxic compounds under normal wearing conditions, though both can off-gas volatile organic compounds (VOCs) during manufacturing and initial use, with odor dissipating within days to weeks.
The brand's record and disclosure
Currex does not publicly disclose material testing certifications, heavy metal screening, or formaldehyde resin use in published marketing or product documentation. The company has no known safety recalls or regulatory warnings associated with RunPro insoles. The brand's silence on PFAS and chemical certifications suggests standard manufacturing oversight rather than transparent third-party validation.
How it compares in its category
Insole chemistry hazards are generally lower than in textiles or footwear uppers because insoles do not rely on azo dyes, formaldehyde-based resins for color fastness, or flame retardant treatments. RunPro sits in the mainstream athletic insole market; competitors like Superfeet, Powerstep, and Scholl use similar EVA and polyurethane blends without documented chemical incidents. No category standard demands allergen or heavy metal testing for insoles, so Currex lacks both advantage and accountability compared to some footwear brands.
If you buy it
Air out new insoles for 24-48 hours before wearing if odor is noticeable; this reduces initial VOC exposure. Avoid exposing insoles to prolonged heat (over 140 degrees Fahrenheit) or direct sunlight for extended periods, as polyurethane can soften or degrade. Replace insoles every 12-24 months depending on running frequency; worn-out foam loses cushioning integrity and may shed microparticles. Hand wash with mild soap and water; do not machine wash or expose to solvents.
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.”
Volatile Organic Compounds (VOCs) / off-gassing
EVA and polyurethane foam insoles may release mild VOCs during first days of use, especially if stored in warm conditions. This is typical and temporary; no health incident reports exist for Currex RunPro specifically.
Foam degradation and microparticle shedding
Polyurethane and EVA degrade over time with wear and heat exposure. Shed microparticles are not documented as a health concern in insole use, but replace insoles before complete compression to minimize this.
Heavy metals in adhesives or dyes
No testing or recalls suggest heavy metal contamination in Currex RunPro insoles. Foam materials do not typically use azo dyes or lead-based adhesives, reducing likelihood compared to leather or textile footwear.
Formaldehyde resins
EVA and polyurethane foam insoles do not rely on formaldehyde-based binders or finishes as textiles do. No public evidence of formaldehyde use in RunPro construction.
Antimony or other flame retardants
Insoles are not treated with flame retardants under consumer safety standards. No reports of antimony or flame-retardant chemicals in Currex RunPro.
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.
