MFM Performance Zero Drop Insoles
Not enough data. Insoles unlikely to contain PFAS, brand discloses nothing.
These cushioned insoles lack known PFAS-involved materials. The brand offers no PFAS openness or certifications, though the material type carries low inherent risk.

What MFM Performance Zero Drop Insoles is made of, ingredients and materials
MFM Performance Zero Drop Insoles use foam cushioning (likely EVA or polyurethane) with a fabric upper layer. Foam materials in insoles are chosen for shock absorption and durability, but both EVA and polyurethane can shed microparticles over time and may off-gas volatile organic compounds (VOCs) when new. The fabric facing is a low-exposure contact surface and typically poses minimal chemical risk unless treated with formaldehyde resins or antimicrobial coatings.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
VOC off-gassing (foam cushioning)
EVA and polyurethane foams commonly release VOCs (formaldehyde, acetone, toluene) during the first few weeks of use. Exposure is minimal in insoles due to distance from nose and skin, but individuals with chemical sensitivity may detect odor.
Microparticle shedding
Foam insoles naturally degrade with compression and flexing, releasing fine particles into socks and footwear. Long-term inhalation risk is low, but individuals with respiratory conditions should monitor for symptoms.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
The brand does not disclose whether the fabric facing is treated with formaldehyde-based resins for wrinkle resistance or antimicrobial effect. No brand recalls or complaints suggest this is present, but absence of disclosure limits certainty.
Source, ATSDR ↗Adhesive or glue residues
Insoles typically use rubber cement or polyurethane adhesive to bond foam to fabric. No specific hazard is documented for products, and adhesive exposure is indirect (contact with skin in shoes only).
Heavy metals
Fabric color treatments may use azo dyes or metal-based pigments. No testing or complaints are on record for this brand, and skin contact risk is minimal because insoles rest inside shoes.

The brand's record and disclosure
The brand does not publicly disclose material safety data, certifications (such as OEKO-TEX or bluesign), or testing results for this product line. No recalls or safety controversies are on record for insoles. The silent stance on PFAS and other chemical content reflects broader industry practice for small footwear-component brands, but leaves end users without independent verification of manufacturing standards.
How it compares in its category
Most retail insoles (drugstore and athletic brands) use similar foam cores with minimal disclosed hazard control. Some premium brands (Superfeet, Powerstep) publish material specs or third-party testing; The brand sits in the mid-market segment where such transparency is uncommon. Zero-drop insoles as a category do not inherently pose greater chemical risk than standard-drop alternatives; the hazard profile depends on foam type and fabric treatment, which is identical between designs.
If you buy it
Air out new insoles in a well-ventilated space for 24-48 hours to allow any initial off-gassing to dissipate. Replace insoles every 12-18 months or when cushioning visibly compresses, as degraded foam may shed particles more readily. Wash the fabric upper with mild soap and water only; avoid heat sources (direct sunlight, dryers) that can accelerate foam breakdown. Do not expose to prolonged moisture, as foam can support mold if not dried completely.
