While retaining the sharp, powerful character of the original, this LTD edition elevates the boot with rare materials and more expressive details, making it a special release for those who value depth and individuality.\n\u003cbr\u003e\u003cbr\u003e\nThe upper is crafted from Avancorpo bullhide, an exceptionally rare leather taken from a single section running from the neck to the back of the hide. Finished using a fully vegetable-tanned process, it offers a firm structure, rich texture, and strong presence. With wear, the leather naturally changes in character, developing deeper tones over time.\n\u003cbr\u003e\u003cbr\u003e\nThe midsole uses rare buffalo bends leather, selected for its exceptional thickness while remaining light and durable. Paired with Biltbuck’s original separate sole, it provides stability and dependable wear. Finished on the A010 Specialty last, the boot features a sharply curved shape and tight-fitting profile, creating a bold silhouette that defines the Lot.444 identity.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"details\" class=\"custom-tab-content\"\u003e\n    \u003cdiv class=\"mobile-scroll-table-2\"\u003e \n\u003ctable
