This LTD limited edition further elevates the model by upgrading the leather to waxed heavyweight kipskin, giving the boot a richer texture and a more substantial presence.\n\u003cbr\u003e\u003cbr\u003e\nThe upper is made from exceptionally thick French kipskin, finished with a wax treatment. Kipskin is known for its fine grain and natural sheen, and the added wax enhances depth and durability. With wear, the leather gradually softens and conforms to the wearer’s foot, developing a comfortable, lived-in feel while maintaining its refined appearance.\n\u003cbr\u003e\u003cbr\u003e\nA premium oak bark–tanned bends leather midsole is used for excellent durability and natural break-in comfort, paired with Biltbuck’s original separate sole for stable, dependable wear. The boot is built on the A012 Pioneer last, a straight-shaped last that offers a more relaxed fit than the A010 last used on the Lot.444. With a width around D–E, it provides an easy, comfortable fit suited for everyday use.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"details\" class=\"custom-tab-content\"\u003e\n   \u003cdiv
