Brands flagged for toxic levels of BPA in athletic socks
What's in your socks matters.
A recent study found over 100 brands selling athletic socks with BPA levels up to 40× above accepted exposure limits. BPA is an endocrine disruptor — and during exercise, elevated body temperature and open pores create a direct pathway for chemical absorption through the skin.
One likely source: contaminated recycled polyester derived from plastic bottles. The same material often marketed as sustainable. PFAS — forever chemicals used for moisture-wicking — were found across major brands as well.
This is exactly why independent testing matters. Every finished product is tested free from PFAS | BPA and screened for 100+ chemicals. Our standard is simple: if the lab's instruments can find it, we don't use it.
