The look alone of our GreenStride™ soles on these men's boots says "comfort." The design is inspired by rows of growing sugar cane. There's a reason for that. They're made with a 75% blend of renewable bio-based material. They're packed with other great stuff too, including ReBOTL™ fabric containing at least 50% recycled plastic, a protective rubber toe, the stain-resistant Defender Repellent Systems® treatment, and tons of performance.
