Built for the hardest jobs, the Timberland PRO Boondock delivers uncompromising protection without sacrificing comfort. The asymmetrical composite safety toe provides maximum toe room while meeting safety standards, so you can move naturally through your workday. Premium waterproof leather combined with a waterproof membrane keeps your feet dry whether you're working in wet conditions or trudging through mud on the job site. Anti-Fatigue Technology in the polyurethane footbed absorbs shock and returns energy with every step, reducing foot fatigue during those long 12-hour shifts. The abrasion-resistant TPU outsole grips securely on any surface, while the rigid external heel cup provides the lateral stability you need when carrying heavy loads or working on uneven terrain. With Microban technology fighting odors and dual-purpose hardware for customized lacing, these boots are engineered to perform as hard as you do, day after day.
