From their website: Our shoes are handmade in Nicaragua by our head cobbler Marvin and his skilled team. -All of our shoes are made using high quality, 100% full grain leather that is custom made for Adelisa & Co. Please note that no two leather hides are exactly the same, therefore slight variations in leather tone and finish are considered normal. Some hides will naturally be lighter or darker and each will present different unique markings. Because this item is handcrafted, slight variations in detail are also considered normal.
