KEEN Footwear's Pittsburgh was inspired by the tough working steelworkers of Pennsylvania. Designed as the ultimate tool for the feet, the Pittsburgh is made with a waterproof Nubuck leather upper and features the classic KEEN wrap rubber toe. A KEEN.Dry waterproof breathable membrane lets moisture out but never in while a removable metamotomical footbed provides unparalleled internal support cradling the foot and delivering excellent arch support. Unique anatomically correct left and right asymmetrical steel toes satisfy ASTM safety standards and help to protect the delicate bones of the toes and feet while providing lightweight comfort. An oil and slip resistant non-marking rubber outsole lays the foundation for a boot that was built to outlast the job at hand. The Pittsburgh is available in steel and soft toe six-inch styles as well as a low style athletic style.
