Designed for rugged durability, the Boondock is designed with a waterproof membrane for abrasion resistance and dry feet. A molded Timberland PRO rubber toe protector gives the shoe increased abrasion resistance and durability. The composite safety toe is shaped on the TITAN last for non-metallic protection and a superior fit. Dual-purpose top hardware allows for instant lacing customization and a superior fit. Features include a combination three-quarter Goodyear welt/cement heel construction, a rigid external heel cup for lateral stability, padded top collar for comfort, a Ever-Guard heel for increased durability, and a fiberglass shank for structural support. Dual-density Dynamic Anti-Fatigue Technology absorbs shock and returns energy at key zones of the foot while providing enhanced moisture management for all-day comfort. The skip and abrasion resistant outsole features deep lugs for traction and the oil-resistant sole is tested for volume swell using EN345 TMP ASTM fuel A 7 Diesel ISO 1817 liquid F for 22 hours and ASTM IRM903 & fuel B for 48 hours.
