PFAS score
Falke · Waterproof Hiking Socks
Falke Trekking TK2 Cool Socks Men's
Lower PFAS concern; merino-dominant socks with no known water-repellent coating, but brand silent on material details.
Falke TK2 Cool Socks are primarily merino wool and synthetics with no disclosed water-resistant or stain-resistant treatment, which typically reduces PFAS risk. Falke publishes no PFAS transparency statements. Without third-party testing or public commitments, assume standard manufacturing practices, lower but not zero concern.

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.
