Inspired by the original yellow boots, these Timberland PRO® Direct Attach boots are waterproof and have 200 grams of insulation to help keep you dry and warm in cold-weather environments. From their premium Timberland® seam-sealed, waterproof leather uppers with comfortable padded collars to their heat-, oil-, slip-, and abrasion-resistant rubber lug outsoles for enhanced traction, these steel-toe boots are ready to get to work. We also added electrical hazard protection and Anti-Fatigue Technology polyurethane footbeds for all-day shock absorption and energy return, plus breathable, moisture-wicking linings made of ReBOTL fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control.
