Proposition 65 refers to the California State Drinking Water and Toxic Enforcement Act of 1986. Proposition 65 requires a warning if a product could potentially contain the 800+ chemicals as stated on the list. We have included the warning on our Red Wing Shoe Company website in compliance with California's Proposition 65. While we do not believe our products are harmful when used, we provide the warning as a result of the California law.
