That’s why we source our hides from Leather Working Group-certified tanneries that use processes to reduce chemical use and the impact on our watersheds. ECO ANTI-ODOR: We've turned to nature to eliminate pesticides and biocides from going into the environment. Our footbeds are infused with probiotic technology that naturally breaks down odor in sweat without heavy metals or hazardous chemicals. PFC-FREE WATER REPELLENCY: Perfluorinated Chemicals (PFCs) are commonly used to repel water on outdoor gear. But these compounds are suspected carcinogens and persist in the environment, so we’ve switched to alternative chemistry that’s safe yet still effective.
