Adventure on the edge. GreenStride™ soles are one of the most eco-conscious and comfortable experiences we’ve ever invented. And now we bring them to boots. We use a 75% combination of renewable natural sugar cane and rubber from trees to make them naturally comfortable, so you’re ready for anything. The waterproof uppers are part Better Leather and part ReBOTL™ fabric made of at least 50% recycled plastic.
