Part of our Project Sustainability® collection, the Rail Python features an innovative, regenerative material: python leather made from Burmese pythons, an invasive species disrupting Florida's native wildlife ecosystem. By removing Burmese pythons from the Everglades, we're helping to preserve native species, their resources and their environment. After months of tannery testing and material samples, we've created our sustainable snakeskin. The Rail Python features an all-over black recycled leather accented with a Burmese python leather tongue, heel tab and trim. Black recycled organic cotton laces and our signature, hand-distressed white gum toe finish off the look. Shipping Notice: The Rail Python sneaker cannot be shipped to California or outside the US.
