If you need protection from water, cold, heat, impacts, compression, punctures, electrical hazards, blood-borne pathogens, slipping, and abrasions, our Gravel Pit 10" tall boots cover all those bases, plus you get all-day comfort and legendary durability. First, we use premium Timberland® full-grain waterproof leather uppers with Ever-Guard™ leather in strategic zones to shield from abrasions, internal waterproof membranes to provide maximum security from water intrusion and blood-borne pathogens, and 400 grams of insulation for warmth when the temperature drops. Then, we added steel safety toes, internal metatarsal guards, flex bands in the shafts for comfort when bending and sitting, steel shanks for support, our exclusive Independent Suspension Network™ (ISN™) system for superior control, support, and agility, and breathable, moisture-wicking linings made of ReBOTL™ fabric containing at least 50% recycled plastic with an antimicrobial treatment for odor control. Finally, for confident, all-weather traction, we use heat-, oil-, slip-, and abrasion-resistant rubber outsoles with Ladder Lock™ heels that help grip ladder rungs.
