These are Danner Manawa boots. They use Chromexcel leather, which provides excellent comfort and fit. The brown core is gradually appearing, and I think they will become even more stylish over time. I've taken good care of them, so they're in good condition. I've maintained them with colorless cream. If you prefer to wear them black instead of showing the brown core, you can use black cream. Due to the nature of Chromexcel leather, there are scratches and scuffs. Also, there may be other damage that I haven't noticed, so please purchase only if you understand this. *Shoe trees are not included. Thank you.
