Stand. Walk. Even crawl. And stay comfortable and dry the whole time. When you need to rely on protection from the mud, grime, and rough terrain underfoot, our Pac boots have you covered. Featuring a cushioning EVA insole and our revolutionary Ankle Fit technology that grips your foot and locks your heel in place, the Pac is just as comfortable as it is durable. It's built with our proven rubber formula that's resistant to tears, abrasions, and a hard day's work in hazardous conditions.
