New Balance Active Crew Socks 6 Pack
Lower PFAS concern. Cotton-based socks with no water-repellent coating treatment typical.
New Balance does not disclose PFAS treatment for these socks. Standard cotton blend athletic socks typically lack water-resistant coatings that require PFAS.

The full breakdown
What it's made of and why it matters
New Balance Active Crew Socks are listed as a cotton blend, which typically means a polyester or nylon admixture for durability and moisture-wicking. Cotton alone is the lowest-risk fiber base in apparel because it requires no flame retardants or water-repellent coatings. The synthetic portions (likely polyester or nylon) are chemically stable when uncoated and present minimal leaching risk during normal wear or washing.
The brand's record and disclosure
New Balance does not publicly advertise independent chemical certifications (such as OEKO-TEX or GOTS) for this mainstream product line, and the brand's PFAS stance is undisclosed. The company has no recorded recalls or regulatory findings specific to chemical contamination in socks. Lack of transparency is typical for athletic basics at this price point but does not indicate a known compliance failure.
How it compares in its category
Uncoated cotton-blend socks occupy the lower-risk end of the apparel spectrum. They avoid the hazards associated with heavily treated performance textiles (fluorocarbon water repellents, antimicrobial finishes). Standard athletic socks across all mainstream brands follow similar safety profiles unless marketed with special finishes or antimicrobial treatments, which these are not.
If you buy it
Wash in warm water (not hot) to prevent potential synthetic fiber shedding and maintain elasticity. No special care is needed beyond standard laundry. Replace when elastic degrades or cushioning flattens, typically after 12-18 months of regular use. Avoid prolonged heat (dryer on high) which can degrade synthetic fibers prematurely.
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.”
Azo dyes
No evidence of restricted azo dyes in New Balance socks. Standard cotton-blend socks use approved reactive or acid dyes in most markets; specific dye chemistry not disclosed but routine industry practice carries low acute risk.
Formaldehyde resins
Cotton-blend fabrics may contain trace formaldehyde from fabric finishing resins used to prevent wrinkling or shrinkage. Levels in finished socks are typically below EU limits (30 ppm) and dissipate with washing, but no product-specific testing is published.
Antimony in polyester
Polyester-cotton blends do not inherently contain antimony unless antimony trioxide is used as a polymerization catalyst in the polyester resin. This is rare in consumer-grade fiber and has not been reported as a concern in athletic socks.
Microfiber shedding
Synthetic fibers in the blend (polyester or nylon) can shed microfibers during washing. Extent depends on fiber quality and finish; uncoated blends typically shed less than heavily treated performance fabrics, but shedding remains a minor environmental concern rather than a direct health hazard.
Heavy metals in dyes or pigments
Regulated dyestuffs in apparel do not contain lead or cadmium in formulated products. No product-specific analysis is available, but compliance with standard dyeing regulations is assumed in major-brand consumer socks.
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.
