ALPINESTARS SP-X BOA Boots - Black/Silver - EU 45 2222024-119-45

If you're logging serious miles on sport and sport touring bikes, your feet need protection that doesn't sacrifice comfort or mobility. The Alpinestars SP-X BOA boots deliver race-derived safety features in a package designed for real-world riding—meaning you get genuine ankle support, impact protection, and the ability to walk confidently off the bike without feeling like you're wearing a tank. The BOA speed lace system and knitted mesh construction make these boots feel more like premium riding shoes than traditional motorsports gear.

Built with Rideknit™ and knitted mesh for breathability and durability, the SP-X features a TPU heel counter and toe slider to absorb impact where it matters most. Alpinestars' Transversal Protection Frame (TPF) provides lateral stability during aggressive lean angles, while dual-density ankle discs work with an integrated shin protector to shield vulnerable areas. The asymmetric heel design follows your natural stride, and the PU midsole keeps your feet comfortable during extended riding sessions and pit stops. A removable OrthoLite® insole accommodates custom orthotics, and the medial zip with BOA speed lace system lets you dial in fit in seconds.
