While we are placing calf and kangaroo boots in the same category as they look very similar to the naked eye, these leathers have some distinct differences to note. For starters, calf is a thicker hide that tends to be more durable and more scuff resistant than kangaroo cowboy boots. On the other hand, kangaroo cowboy boots are lighter in weight, very soft, and mold to the foot with ease. Additionally, we recommend kangaroo for the tops if you are looking for intricate inlay work as it is easier to work with. In essence, if you are looking for lightweight and malleable, we would recommend kangaroo for your custom cowboy boots, yet if you are a little tougher on your boots and don't mind a little extra weight, calf is the way to go.
