Authentic. These beautiful y2k era boots are a bit too small for me. They are a 38. This brand runs small. Boots are 9.5 inches heel to toe. They are 16.5 inches tall. The upper is 6.5 inches across (measured flat) at opening. Condition: They have moderate creasing at toe box, black leather in excellent condition at toe and heel with only minor scuffs. Leather upper with marks and one area of some staining as shown in images. It is far less noticeable in natural light but I wanted to point it out using a spotlight. Moderate wear to sole, see image.
