The Zumbro AK370 is the dry-land sibling of Rock Rooster’s waterproof wide-fit — same 6-inch height, same generous wide-width toe room, same ASTM 2413 steel toe and EH protection, built on an oiled Crazy Horse leather upper instead. PORON XRD returns energy with every step, COOLMAX moves moisture out on hot days, and the slip- and oil-resistant rubber outsole holds the floor when the floor doesn’t cooperate.
What’s the difference between the Zumbro AK370 and the waterproof AK372? The Zumbro AK370 shares the same wide steel-toe, EH-protected build but skips the waterproof membrane in favor of a breathable COOLMAX-lined Crazy Horse leather design.
