Stance Runner Light Crew Black Socks
Lower concern, basic cotton-blend socks with no reported PFAS treatment, though brand offers no public commitment.
Stance Runner Light Crew socks are standard cotton-blend athletic socks with no disclosed water-resistant or stain-resistant coating. The brand makes no public PFAS claims or disclosures. Cotton fibers themselves carry minimal PFAS risk unless treated for performance finishes, which Stance does not advertise for this product line.

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.
