Unlike beauty products or food items, shoes don’t come with an ingredients label. It’s impossible to tell just by looking what kind of glue was used, the factory conditions they were made under, and how much, if any, of the materials were recycled or are recyclable. The sad truth is that the creation of most shoes made in the U.S.—more than 95 percent—began somewhere in a slaughterhouse and ended in a toxic chrome leather tannery. But good news! After years of turning out hemp flip flops, the sustainable and socially conscious shoe industry is making its mark on the fashion scene.
