Georgia internal metatarsal cc steel toe work boot is a safety boot that meets three astm standards! Beyond that, it’s also ultra-comfortable. Safety first: it comes with a steel toe and an astm-certified antimpact internal met guard. This boot meets astm standards for protective toe, electrical hazard and protective metatarsal, keeping you safe on the job. The rubber hammer outsole resists oils, chemicals, heat and abrasions, but also is cushioning and flexible. Georgia boot patented comfort core technology is a specially-designed, polyurethane, energy-return heel plug that stores energy as it’s compressed by your foot, then releases that energy as you lift your foot. The inserts also feature an air flow system that forces air through the footbed as you walk to keep your feet cool and dry. Goodyear welt construction enhances the boot’s strength and flexibility.
