The North Face Hiking Crew Socks
Lower concern, standard socks aren't typical PFAS application areas, but no transparency from brand.
Merino wool and standard synthetics without known waterproof coatings. The North Face provides no PFAS disclosure, though socks themselves are lower-risk products than treated outerwear.
