CURREX Acepro Insoles
No PFAS concerns documented; brand silent on treatment.
Currex Acepro insoles use foam and textile construction with no known Teflon-family coating coatings or waterproof treatments disclosed. Standard sports insole materials carry lower PFAS concern.

The full breakdown
What it's made of and why it matters
CURREX Acepro insoles use foam cushioning (likely EVA or polyurethane) topped with textile covering. Foam cushioning in insoles does not leach significantly under normal use because it remains dry, room-temperature, and not in direct contact with food or heated surfaces. The textile upper may contain synthetic fibers, but insoles experience minimal friction or wear that would generate microplastics during typical wearing.
The brand's record and disclosure
CURREX has not published material composition disclosures, safety certifications (such as OEKO-TEX or similar textile standards), or manufacturing transparency statements on public record. The brand's silence on PFAS treatment is notable but not unusual for insole manufacturers, most of whom do not publicly address water-repellent finishes. No recalls or safety controversies for this product line are documented in consumer safety databases.
How it compares in its category
Foam insoles are generally lower-risk than coated textiles, adhesive-heavy footwear, or dyed athletic wear. CURREX Acepro sits in the mid-premium market segment; comparable brands (Superfeet, Powerstep) similarly lack detailed material transparency but operate under comparable manufacturing norms. Insoles avoid many hazards inherent to tight-fitting garments or footwear with heavy solvent-based adhesives.
If you buy it
Air-dry insoles between uses to prevent bacterial or fungal growth in damp foam. Replace every 6 to 12 months once foam begins to compress noticeably, as degraded cushioning loses support and may shed microparticles. Wash textile covers by hand in lukewarm water rather than machine washing if manufacturer instructions permit, to minimize fiber shedding and foam stress. Store in a cool, dry environment away from direct heat or sunlight, which can degrade foam polymer structure.
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 binding
The textile upper may contain formaldehyde-based dyes or resin finishes common in athletic footwear; no independent test results are published for this model. Skin contact is minimal and off-gassing risk is low in open-air insole use.
Azo dyes in colored textile
Colored fabric covering may contain azo dyes that can release aromatic amines under sweat exposure; no certifications (such as OEKO-TEX Standard 100) are documented to exclude them. Direct skin exposure is present but brief and intermittent.
Foam polymer degradation and microparticle shedding
EVA or polyurethane foam degrades over time and with compression; worn insoles may shed small particles into socks and skin. This is not acutely toxic but represents unnecessary particulate exposure over months of use.
Bacterial or fungal growth in damp foam
Insoles worn in moist environments (sweaty feet, wet conditions) can harbor microorganisms if not dried regularly. This is a hygiene concern rather than a chemical hazard but is common across foam insole products.
Adhesive leachables at textile-foam interface
No specific information is available on the adhesive used to bond the textile cover to foam; typical insole adhesives are solvent-free or low-VOC. No recalls or complaints are on record for this product.
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.
