Our Super Rain Forest boot is made with two layers of 7 oz leather around the toe and heel cap, where the Rain Forest is one layer of 7oz leather (An average boot is typically made with 5oz leather). The Super Rain Forest is made on our most universally fitting 610 last, so it's made to fit almost every foot. The Rain Forest however, is made on a slightly more narrow 650 last. Both boots are US-Made, durable and offer waterproof GORE-TEX liners.
