Timberland 6" Boot - Men'sThe inspiration behind the Timberland Earthkeepers 6" Boot is born out of a desire to create an original, outdoor-tested boot with a smaller environmental footprint than other boots may have. These boots are made with one or more major components containing at least 50% recycled PET — the plastic used to make soda bottles. The upper is made with premium, waterproof leather for comfort, durability and abrasion resistance, and has a zoned force distribution footbed that spreads impact shock, creating a pressure-free zone. The Anti-fatigue footbed provides all-day comfort. 100% recycled PET lining and 100% organic cotton laces. Green Rubber™ (42% recycled rubber) outsole. Removable insole.
