The ultimate in lightweight comfort, our men's Helix HD waterproof boots also provide the durable performance and protection you need for long hours in tough conditions. Starting with Premium Timberland® waterproof leather uppers, we added internal waterproof membranes for maximum waterproof protection and blood-borne pathogen resistance and then stitched on our molded Timberland PRO® rubber toe guards for an extra layer of protection. Other safety features include composite safety toes, electrical hazard protection, and fiberglass shanks for extra structural support. Their Anti-Fatigue Technology footbeds offer shock absorption and energy return, while their breathable, moisture-wicking mesh linings are made of ReBOTL™ fabric containing at least 50% recycled plastic. Plus, our heat-, oil-, slip-, and abrasion-resistant, non-marking rubber outsoles feature Ladder Lock™ heels that help grip ladder rungs.
