The Timberland PRO Powertrain Safety Toe SD+ work shoe balances the need for breathability and the need for safety with traction designed for variable cold-to-hot environments and ASTM-rated Electro Static Dissipative performance for jobsite safety. Style number: A1Q3L001 and A1ORR065. Work shoes feature an Ariaprene upper that bonds breathable mesh with flexible foam core. Ghillie lace-up closure for preferred fit. Cement construction adds flexibility and reduces break-in time. Lightly padded collar and tongue add comfort and stability. TPU overlays lend durability to the heel, laces, and toe bumper. Mesh lining with antimicrobial treatment reduces odor. Fiberglass shank provides structural support. Anti-fatigue technology in the footbed utilizes an open-cell PU foam to provide shock absorption and reactive energy return, targeted through the arch. Open-cell footbed provides constant static-dissipative performance. Non-marking TPU outsole is oil resistant, slip-resistant, and heat resistant up to 248 degrees Fahrenheit. All-weather outsole traction is designed for grip during wet or frosted ice surfaces. CarbonShield composite safety toes in an anatomic, asymmetrical design.
