The full breakdown
What it's made of and why it matters
CURREX RunPro insoles use EVA (ethylene-vinyl acetate) foam as the core cushioning material, paired with textile uppers and a TPR (thermoplastic rubber) base. EVA foam is a closed-cell polymer that does not readily leach chemicals during normal wear at body temperature; it is chemically stable and widely used in footwear without documented toxicity concerns at consumer exposure levels. The textile blend and TPR base are standard commodity materials in athletic insoles and do not typically contain restricted additives in this product class.
The brand's record and disclosure
Currex does not publicly disclose detailed material safety data, certifications (e.g., OEKO-TEX, GOTS), or chemical testing results for the RunPro line on their website or marketing materials. No major product recalls, safety controversies, or third-party safety alerts have been documented for this brand or product. The brand's silence on PFAS and other chemical screening is consistent with many athletic insole manufacturers that do not market safety as a primary differentiator.
How it compares in its category
EVA foam insoles are one of the safest material choices in the footwear accessory category; they are preferred over gel-based or heavily treated alternatives because they are inherently low-migration. Most competing brands (Superfeet, Powerstep, Sidas) use similar EVA or polyurethane cores with textile covers. Unlike some orthotics with adhesive or resin binders, the RunPro line shows no evidence of problematic adhesive chemistry or heavy manufacturing residues.
If you buy it
Store insoles in a cool, dry place away from direct sunlight to preserve foam integrity; EVA can degrade and become brittle over years of exposure to UV or extreme heat. Wash textile covers by hand with mild soap if needed, but avoid prolonged soaking or machine washing, which can weaken adhesives. Replace insoles every 12-18 months of regular use, or when cushioning noticeably compresses or cracks appear in the foam. Do not heat-treat or microwave EVA insoles, as sustained temperatures above 60°C can cause material breakdown.
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 textiles
No public evidence of formaldehyde-resin treatments (wrinkle-resistance, sizing finishes) in CURREX RunPro textile uppers; standard athletic insole textiles typically avoid such finishes due to moisture exposure during use.
Azo dyes and color fastness
Textile cover dyes are not disclosed; azo dyes are used in some athletic textiles but restricted azo compounds are regulated in EU markets. No recall or complaint history for color bleeding or allergic reactions in this product.
Antimony in polyester
Antimony catalyst residues are rare in athletic insole textiles at levels of concern; no evidence of polyester-specific treatment in this product that would concentrate antimony.
EVA foam off-gassing and volatile organic compounds
New EVA insoles may emit weak volatile odors during initial use due to residual manufacturing volatiles; this is typically mild and diminishes within days to weeks. No long-term inhalation risk from properly manufactured EVA at room temperature.
Microplastic shedding during wear
EVA and TPR materials can shed small particles during repeated compression and friction; insoles are not heated or aggressively worn in ways that accelerate particle generation, but microscopic wear is inherent to all foam footwear.
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.
