New Balance Women's Cushioned Ankle Socks
Lower concern, standard socks without water treatment.
Cotton-based ankle socks with no known water-repellent coating or stain-resistant treatment. New Balance does not disclose PFAS use, but basic socks typically pose lower risk than coated or waterproofed textiles.

The full breakdown
What it's made of and why it matters
New Balance Women's Cushioned Ankle Socks are a cotton-synthetic blend, typically combining cotton for breathability and durability with polyester or nylon for stretch and moisture-wicking. This blend is standard across athletic socks and avoids high-risk materials like pure acrylic or certain flame-retardant treatments. The synthetic portion is not inherently hazardous at normal wearing temperatures, and cotton content reduces reliance on petroleum-based fibers.
The brand's record and disclosure
New Balance does not publicly emphasize chemical transparency for apparel beyond general compliance statements. The brand maintains ISO 9001 manufacturing standards and adheres to relevant apparel safety regulations (Oeko-Tex, REACH, restricted substance lists) but does not publish detailed chemical use reports specific to sock lines. No notable product recalls or chemical contamination incidents for this product line are on record.
How it compares in its category
Cushioned athletic socks from major brands like Nike, Adidas, and Brooks follow similar cotton-synthetic formulations with comparable safety profiles. New Balance's lack of explicit sustainable or organic certification is typical for mainstream athletic socks at this price point; certified organic socks are available but cost significantly more. The material composition and manufacturing opacity here mirrors industry standard rather than falling behind or ahead.
If you buy it
Wash socks in cool to warm water to avoid shrinkage and potential stress on elastic components; high heat can degrade synthetic fibers but poses no direct chemical release risk. Replace socks when elastic loses tension or cushioning flattens, typically every 12-18 months with regular use. Store in a dry location to prevent mildew growth, especially in high-moisture environments. No special care protocols are required beyond standard laundry practices.
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 finish treatments
No published evidence of formaldehyde-releasing finishes in New Balance cushioned socks; cotton-blend athletic socks typically avoid wrinkle-resistant treatments that require formaldehyde-based resins.
Azo dyes in synthetic fibers
Black or dark-colored socks may use azo dyes in the polyester or nylon components; however, these are permitted under REACH and EU regulations and pose minimal dermal risk when colors are properly fixed during dyeing.
Antimony in polyester fibers
Polyester production may involve antimony catalysts, which can trace into finished fabric in very small quantities; migration to skin is negligible for apparel worn briefly and not repeatedly heated.
Synthetic fiber degradation with heat
Nylon and polyester in athletic socks do not release harmful volatiles or monomers at normal body temperature or typical laundry heat; degradation risk is structural (elastic loss) rather than chemical.
Residual dyes or finish allergens
A small population with sensitive skin may react to residual dye molecules or finish treatments; pre-washing new socks and avoiding prolonged wet contact reduces this minimal risk for most wearers.
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.
