Offering protection in every direction, our sturdy steel-toe work boots also feature our unique Timberland PRO 24/7 Comfort System that meets the most rigorous worksite demands while helping reduce foot fatigue by supporting your arch and cushioning every step. Beginning with uppers constructed of a combination of Premium Timberland leather and highly abrasion-resistant Ever-Guard leather sewn together with heat-resistant thread, this ankle boot offers superior flexibility and durability with a steel shank and electrical hazard protection. Next, we included an internal metatarsal guard made of a breathable, open-cell polyurethane and rubber for impact resistance. Finally, we added a breathable, moisture-wicking lining that's made of ReBOTL material containing at least 50% recycled plastic and our heat-, oil-, slip-, and abrasion-resistant, non-marking rubber outsole.
