The ultimate in lightweight comfort, our men's Timberland PRO® Helix HD internal metatarsal guard boots also provide the durable performance and protection you need for long hours in tough conditions. Starting with premium Timberland® full-grain leather uppers, we added internal SKYDEX® metatarsal guards to absorb and redirect the forces from falling objects and then stitched on our molded Timberland PRO® rubber toe guards for an extra layer of protection. Other safety features include composite safety toes featuring Carbon Shield™ technology, electrical hazard protection, and a fiberglass shank for 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 with an antimicrobial treatment for odor control. Plus, our heat-, oil-, slip-, and abrasion-resistant, non-marking rubber outsoles feature Ladder Lock™ heels that help grip ladder rungs.
