9060 Flatbox Beckman Boot in Black Klondike – Blue Owl Workshop。The Red Wing 9060 Flatbox Beckman is a limited-production, classic service boot featuring unique Black Klondike \"tea-core\" leather that patinas to reveal brown undertones with wear, an unstructured \"flat box\" toe for a customized, collapsed look, and a durable Gro Cord sole. Key Features Black Klondike Leather: This teacore leather starts black but wears away with use to expose a brown core, creating a unique patina. Unstructured Toe (\"Flat Box\"): The absence of a stiff toe box allows the toe area to soften and flatten over time, creating an authentic look from the 1930s and 1940s. Gro Cord Medallion Outsole: A durable, classic rubber sole inspired by 1930s Red Wing boots, offering a non-slip function. Goodyear Welt Construction: A traditional and durable construction method for boots. Last No. 8: The wooden pattern used for this model, similar to other Beckman boots.
