Why this grade
Waterproof / stain-resistant treatment
water-repellent coating treatments have historically used PFAS.
Category baseline
clothing is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
The full breakdown
What it's made of and why it matters
These boots feature a leather upper with an applied waterproof treatment (water-repellent coating, or water-repellent coating), plus likely synthetic or leather lining and rubber sole components. Leather itself is a processed animal material prone to residual tanning chemicals, while the waterproof finish is the primary chemical concern since water-repellent coating coatings historically relied on PFAS compounds, though alternatives exist. The wide fit does not change chemical composition, only fit geometry.
The brand's record and disclosure
Danner, a Timberland subsidiary, maintains a general sustainability statement but does not publicly disclose water-repellent coating chemistry or PFAS avoidance commitments on product pages. The brand has no known major footwear recalls related to chemical hazards in recent years. Transparency on waterproof treatment composition is absent from standard Danner communications, making independent verification difficult.
How it compares in its category
Premium hiking boots typically use either PFAS-based or fluorine-free water-repellent coating finishes; Danner's specific choice is unlisted. Competitor brands like Salomon and Merrell have begun disclosing water-repellent coating type (some using PFOA-free waxes or polyurethane), whereas Danner remains silent. Price point (USD 300+) suggests professional-grade construction but does not guarantee lower-chemical inputs.
If you buy it
Store in a dry, well-ventilated space to prevent mold growth in damp lining material. Reapply water-repellent coating annually using manufacturer-approved products; do not machine wash, which degrades treatment. Break in gradually to avoid blistering. Contact Danner directly to request water-repellent coating composition data if PFAS exposure is a concern for your household; silence on this detail should inform your decision.
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 in tanning residues and synthetic lining
Leather tanning and synthetic fabric backing in footwear may retain formaldehyde or formaldehyde-releasing compounds. No specific testing data is publicly available for this model; risk is typical for conventionally tanned leather boots at this price point.
Azo dyes in leather and fabric dyeing
Leather and lining dyes may include azo compounds, which can break down into carcinogenic amines under sweat and friction. Danner does not certify against azo-restricted dyes; this is a category-wide concern for untested leather goods.
Coating degradation and microparticle shedding
water-repellent coating coatings on all boots gradually wear with use, releasing microscopic polymer particles into soil and water. This is an inherent property of fluorinated and non-fluorinated water-repellent coating finishes; regular reapplication increases cumulative exposure.
Antimony in polyester components
If synthetic lining or webbing contains polyester, antimony oxide (a catalyst used in polyester production) may be present in trace amounts. Danner does not disclose lining material composition for this model.
water-repellent coating chemistry unknown (PFAS status unconfirmed)
Waterproof treatment type and fluorine content are not disclosed by the brand. Given no public PFAS-free commitment, PFAS-based water-repellent coating remains plausible, making this the primary chemical uncertainty for this product.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 35% 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.
