These boots have been worn semi-regularly for a couple seasons but still have a lot of life in them! The leather has been treated with a Blundstone leather protectant specifically for black leather. These are AU size 8.5 (see pic with size stamped on bottom), which i find fits a US Women’s 11 or Men’s 9.5. Be sure to check out Blundstone’s size chart to verify it will fit. Questions? Feel free to message me!
