These Cofra boots are made specifically for asphalt workers. They feature a completely smooth and high heat-resistant sole, and a composite safety toe to keep you safe. They also feature a thermic insole to insulate your foot from high temperatures and a puncture-resistant fabric plate to keep you extra protected. We receive great feedback on these and have many repeat buyers. Please note, these Cofra boots come in a wide width only to provide for a generous fit.
