Currex · Synthetic Athletic Insoles & Orthotics
Currex RunPro - High Profile | Size: Small | Color: blue
Insole shoe insert; waterproof treatment likely uses PFAS. Skip if PFAS-conscious.
Currex RunPro insoles are designed for water resistance. No public PFAS disclosure or testing available; water-repellent coating foam insoles typically use fluorinated coatings as standard.

The full breakdown
What it's made of and why it matters
Currex RunPro insoles use closed-cell foam (EVA or polyurethane blend) as the core, chosen for cushioning and arch support in running shoes. The upper textile likely receives water-repellent coating (water-repellent coating) treatment to shed moisture, a common finish in athletic footwear that frequently relies on fluorinated compounds (PFAS). Foam insoles can shed microparticles with wear, though the amount inhaled or absorbed remains poorly quantified in casual athletic use.
The brand's record and disclosure
Currex does not publicly disclose chemical composition, manufacturing certifications (such as OEKO-TEX or bluesign), or use of PFAS-free water treatments. No major recalls or safety controversies are on record for this product line. The brand's silent stance on PFAS and chemical inputs contrasts with competitors (like Superfeet or some premium brands) that publish transparency reports or certifications.
How it compares in its category
RunPro insoles are mid-tier in the athletic insert market; similar foam-based competitors (Powerstep, Sof Sole) also lack detailed chemical disclosure. Some premium alternatives (such as insoles with explicitly PFAS-free or organic certifications) exist but at higher cost. The blue colorant itself is not a known concern for commercial athletic foam, though proprietary dyes are not disclosed.
If you buy it
Replace insoles every 6 to 12 months or when cushioning visibly compresses, as degraded foam may shed more microparticles. Do not machine wash or submerge repeatedly, as this can accelerate coating and material breakdown. Avoid storing in direct heat or sunlight, which can degrade both foam and any surface treatment. If you are PFAS-sensitive, contact Currex directly to request material safety data; silence on this issue after inquiry suggests they may not track or use PFAS-free alternatives.
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.”
PFAS in water-repellent coating textile treatment
Most athletic shoe water-repellent coating finishes use fluorinated compounds; Currex does not disclose whether RunPro uppers use PFAS-free alternatives. Direct skin contact is minimal (insole sits inside shoe), but manufacturing and disposal pathways carry PFAS load.
Microplastic shedding from foam core
EVA and polyurethane foams can release particles as they age and compress. Inhalation risk is low in typical use, but disposal into landfill or water systems is a concern.
Heavy metals or azo dyes in colorant (blue)
No recalls or test data on record for Currex RunPro blue colorant. Commercial athletic foam colorants are generally regulated, but Currex does not publish pigment sourcing or testing.
Antimony in polyester or polyurethane
If the foam or upper textile contains polyester or polyurethane, antimony may be used as a catalyst during manufacture. Levels in finished consumer products are typically low and not expected to leach in normal wear.
Formaldehyde in adhesives or binders
Foam insole lamination and attachment to the base may use formaldehyde-containing adhesives. No specific data on Currex formulations; typical exposure is minimal if the product is fully cured before sale.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 42% 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.
