Bringing modern innovation and comfort, the McKinney M.U.T.™ builds on Kodiak's heritage of purpose-built boots. Behind that rugged, durable leather is a 100% waterproof/breathable membrane that extends throughout the bellowed tongue for a fortress against the elements. Our technology, the Multi-Use Toe (M.U.T.) is designed for pushing, holding and propping up materials while you work. Underneath the rubber toe cap sits a CSA and ASTM approved composite toe to keep you safer, and an oil- and slip-resistant, non-marking rubber outsole that's backed with a composite plate to maximize protection and safety on the jobsite.
