Built for maximum, industrial-grade jobsite performance, our 9" tall Timberland PRO® Bannack work boots are designed to handle extreme heat and even molten metal. For specialized safety, these boots feature flame-resistant Premium Timberland® leather uppers, our internal Anti-Fatigue Technology anatomical metatarsal guards, non-magnetic alloy safety toes shaped for a roomier fit, electrical hazard protection, durable and heat-resistant protective thread on the uppers and welts, and heat-, oil-, slip, and abrasion-resistant rubber outsoles with Ladder Lock™ heels that grip ladder rungs. To ensure all-day comfort, we added our exclusive Independent Suspension Network™ (ISN™) system for superior control, support, and agility, plus SmartWool® natural fiber on the top collars and tongues to naturally repel odor-causing bacteria and breathable, moisture-wicking linings made of ReBOTL™ material containing at least 50% recycled plastic.
