Currex · Synthetic Athletic Insoles & Orthotics
CURREX CLEATPRO Insoles
Lower concern, but brand silent on PFAS; likely safe materials.
Currex CleatPro insoles use foam, textiles, and synthetics with no known PFAS coatings. Brand provides no PFAS disclosure, but common insole materials pose lower risk than water-resistant gear.

The full breakdown
What it's made of and why it matters
CURREX CLEATPRO uses closed-cell foam cushioning (likely polyurethane or EVA) with a textile upper layer and synthetic rubber or plastic base. Foam cushioning in athletic insoles is chosen for shock absorption and durability rather than for chemical risk, and closed-cell construction limits material breakdown under normal foot-temperature use. The textile upper typically serves as a comfort layer and sweat management surface; synthetic base provides structural support. This material stack is standard across the insole category and carries low inherent toxicity risk under normal conditions.
The brand's record and disclosure
Currex is a performance-footwear brand with no major product recalls or chemical contamination incidents on record in the public domain. The brand does not publish detailed material safety data sheets or third-party certifications (such as OEKO-TEX or similar textile testing) for these insoles. Silence on PFAS is typical for insole manufacturers and does not signal a red flag in this category, though transparent disclosure would be preferable. No documented controversies regarding heavy metals, formaldehyde, or flame retardants specific to Currex products.
How it compares in its category
Athletic insoles occupy a low-risk material category compared to apparel textiles or cushioned furniture. Most competitors (Superfeet, Powerstep, Spenco) use similar polyurethane or EVA foam with textile covers; none routinely publish independent safety testing. CURREX CLEATPRO is neither more nor less transparent than category peers. The foam-based approach is materially safer than gel insoles (which can degrade and leach) or heavily treated antimicrobial textile insoles.
If you buy it
Store insoles in a cool, dry place away from direct heat or sunlight to slow foam degradation; do not expose to temperatures above 60-70 C (140-160 F). Hand-wash the textile upper with mild soap if needed; avoid machine washing or bleach. Replace after 12-18 months of heavy use or when cushioning visibly compresses and no longer rebounds. No special precautions required for skin contact; standard foot hygiene applies. If you have sensitive skin or suspect contact dermatitis, discontinue use and test on a small area first.
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 in textile finishes
Athletic insole textiles may receive shrink-resist or antimicrobial finishes; no cases of formaldehyde contamination in insoles have been documented in public recall data. Standard foam insoles are not treated with resin finishes typical of apparel.
Azo dyes in textile upper
If the textile upper is dyed, non-regulated azo dyes could theoretically be present, though skin contact risk is minimal in foot-worn insoles and dyes are typically applied to synthetic yarns. No brand-specific testing or incidents on record.
Polyurethane foam degradation and leaching
Over time, polyurethane foam can break down under moisture and heat, potentially releasing oligomers or residual chemicals. This is a material-class risk rather than a brand-specific issue; replacement at 12-18 months minimizes exposure.
Antimicrobial treatments (triclosan, silver nano)
Some insole brands apply antimicrobial coatings to reduce odor; no evidence that CURREX CLEATPRO uses these. If present, they would pose minimal dermal risk but unnecessary chemical burden.
Heavy metals in synthetic dyes or rubber base
Synthetic rubber bases and synthetic dyes may contain trace cadmium or lead in unregulated manufacturing; no recalls or test failures for Currex insoles on record. Risk is low in this product category.
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.
