This is the traditional Muck Boots Chore Steel Toe Met Guard Work Boot with a Poron XRD Metatarsal Guard, offering extreme impact protection. Poron is a soft, flexible, wearable protective material that gets hard when impacted. It offers consistent, repeated impact absorption for reliable performance throughout the life of the boot. Underneath your foot, a steel shank adds additional arch support and puncture protection. Starting from a new outsole designed for slip resistance, and using compounds that are oil, abrasion and cut resistant, the platform extends with uppers built for the toughest jobs.
