Men's Timberland Pro TP Helix HD Comp T H Work Boots 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.
