One of the most unique riding boots we've seen in a long time. Alpinestars Firm boots are a vintage / military style boots packed with class-leading protection and a breathable waterproof membrane for all-weather performance. The black color does not come with a waterproof membrane and therefore performs better in warmer temperatures. The hidden zipper makes putting these boots on a breeze. We love the height of these motorcycle boots as it offers serious ankle support and protection. Classy, stylish, protective and indisputably comfortable.
