The Alpinestars SP-X Boa Drystar Boots are all-weather touring boots built for riders who need waterproof protection and reliable performance across varied terrain. The main upper combines advanced microfiber, knitted mesh, and co-injected TPU with Lycra to balance comfort, breathability, and durability.
