The look alone of ther GreenStride soles on the Greenstride Motion 6 sneaker boot from Timberland 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 sugar cane and rubber from trees. They're packed with other great stuff too, including ReBOTL fabric containing at least 50% recycled plastic, and tons of performance.
