Alpinestars SP-X BOA Motorcycle Boots

SP-X BOA Boots - Black/Silver - EU 46

The Alpinestars SP-X BOA motorcycle boots are compact, mid-height sport riding boots designed for riders who want dependable protection, comfortable walking performance, and an easy under-pant fit. Built for sport and sport-touring applications, these black and silver boots combine Rideknit® material, knitted mesh, and seamless thermo-welded panels for a flexible, streamlined upper. The Alpinestars SP-X BOA boots are sized for EU 46 and are identified by manufacturer and vendor part number 2222024-119-46.

Protection: An integrated shin impact protector, dual-density ankle discs, TPU heel counter, reinforced toe slider, and TPU shift pad help protect key areas during riding. The Alpinestars Transversal Protection Frame (TPF) in the sole is designed to resist impact and limit excessive bending or twisting while preserving practical flexibility. An asymmetric rear heel supports a natural stride and improves stability when walking off the motorcycle.

Comfort and closure: Knitted flex zones at the front and rear support freedom of movement, while the PU midsole incorporates a dual-cushion heel compound for improved walking comfort. A removable OrthoLite® footbed provides cushioning and breathability. The medial zipper works with the BOA® speed-lace system to provide quick entry and a compact, precise closure. The result is a practical sport boot for riders seeking more coverage and protection than casual footwear without the bulk of a full race boot.

Fitment: The Alpinestars SP-X BOA boots fit sport and sport-touring riders seeking an over-the-pant or under-technical-riding-pants design. Select EU 46 for the intended size. Brand: Alpinestars. Manufacturer and vendor part number: 2222024-119-46.
