The Alpinestars SP-X BOA motorcycle boots are compact, mid-height sport riding boots designed to fit comfortably under technical riding pants. Built for sport and sport-touring riders, the SP-X combines motorcycle-specific protection with walking comfort for use on and off the bike. This black EU 44 model features a streamlined over-the-pant profile and is identified by Alpinestars part number 2222024-1100-44.
Construction: The upper combines Rideknit® material, knitted mesh, and seamless thermo-welded components for flexibility, breathability, and a close-fitting feel. A medial zipper and BOA® speed-lace system provide quick entry and precise closure. Knitted flex zones at the front and rear support natural movement while walking or riding.
Protection: The SP-X incorporates an integrated shin impact protector, dual-density ankle discs, a TPU heel counter, and a reinforced TPU shift pad. The toe slider adds additional abrasion and impact resistance. Alpinestars’ Transversal Protection Frame (TPF) in the sole helps protect against impact while limiting excessive bending and twisting. The asymmetrical rear heel design supports a natural stride and improves stability when walking off the motorcycle.
Comfort: A PU midsole with an integrated double-cushioned heel compound and removable OrthoLite® insole helps provide support and cushioning during extended wear. The sole design balances motorcycle protection with everyday mobility, making these boots suitable for riders who want more coverage than casual riding footwear without the bulk of a full race boot. The Alpinestars SP-X BOA boots fit sport and sport-touring applications and are supplied in black, EU size 44.
