Brooks Replacement Insoles Cushion Neutral Mens sz 10.5
Lower PFAS concern. Standard foam insoles rarely use PFAS.
These replacement insoles use common cushioning foams without typical PFAS-prone coatings. No waterproofing or stain treatment is mentioned.

What Brooks Replacement Insoles Neutral Mens sz is made of, ingredients and materials
Brooks replacement insoles are foam cushioning, most likely ethylene-vinyl acetate (EVA) or polyurethane-based closed-cell foam. EVA is widely used in footwear because it resists compression set, drains moisture, and does not easily leach chemicals into skin contact under normal wear. Polyurethane foam is chemically inert once cured and poses minimal dermal absorption risk at body temperature. Neither material is known to off-gas volatile organic compounds (VOCs) at levels of concern during typical indoor storage or use.
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.
Microplastic shedding or degradation
Foam insoles do shed fine particles with age and compression, especially at seams or under pressure zones. However, foot-to-insole contact is not a significant ingestion or inhalation route; shed particles remain primarily in socks and shoes.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Volatile organic compound (VOC) off-gassing
EVA and polyurethane foams used in insoles do not off-gas measurable VOCs during storage or wear at room temperature. No reports or recalls exist for odor or respiratory irritation from Brooks insoles.
Allergens in foam additives
Brooks does not disclose additives, colorants, or antimicrobials in insole foam. No documented cases of contact dermatitis or allergic reaction to Brooks insoles exist in public records.
Formaldehyde / VOCs
Insole foams do not require formaldehyde-based antimicrobial or resin treatments typical of textiles or coated fabrics. Standard closed-cell foam structure resists microbial growth without chemical additives.
Source, ATSDR ↗Heavy metals
Brooks insoles are typically neutral gray, white, or blue; limited pigmentation reduces risk. No lead, cadmium, or chromium contamination has been reported in foam-based insole products.

The brand's record and disclosure
Brooks does not publish detailed material safety data sheets or third-party certifications for individual insole products. The company has not faced documented recalls or regulatory actions specific to insole foam toxicity. Brooks maintains a general supply chain transparency policy but does not disclose PFAS use in footwear components. This silence is typical across the industry for insole manufacturers and does not indicate a hidden problem, only lack of market pressure for disclosure.
How it compares in its category
Replacement insoles as a category carry lower chemical risk than full shoes, since they involve limited material variety and no dyes, adhesives, or finishes. Brooks insoles are positioned in the mid-market comfort tier and are chemically comparable to insoles from New Balance, Superfeet, and Saucony. No insole category has established microplastic migration or formaldehyde release concerns under normal use, making this product class lower-risk than apparel textiles or adhesive-heavy footwear.
If you buy it
Store insoles in a cool, dry place away from prolonged heat or direct sunlight to preserve foam elasticity. Replace them every 6-12 months depending on activity level and visible compression; worn insoles lose cushioning but do not become toxic. Hand wash with mild soap and cool water if they absorb odor, then air dry completely before reinsertion. No special precautions are needed during normal foot contact.
