Alpinestars SP-X BOA Boots — EU 38, Mid-calf, Black

The SP-X BOA boots are a sleek sport boot engineered to sit comfortably under technical riding pants while delivering superior walking capability and everyday usability. Designed for riders who want protection without the full race-boot silhouette, these compact, mid-height boots balance on-bike performance with off-bike comfort.

Construction

Lightweight knit panels combine with seamless thermo-welded overlays to create a flexible yet abrasion-resistant upper. The lower unit incorporates a structured heel counter, a reinforced toe area and a Transversal Protection Frame (TPF) integrated into the sole to resist impacts and prevent excessive bending or twisting.

Protection

• Integrated shin impact protector for frontal coverage.
• Dual-density ankle discs for managed energy absorption.
• Reinforced TPU shift pad and replaceable toe slider for abrasion resistance.

Comfort & Sole

Flex zones at key points allow natural movement while a PU midsole with a double-cushioned heel compound and a removable OrthoLite® insock enhance walking comfort. The outsole features an asymmetric back heel to promote a natural stride and improved off-bike stability.

Closure

A medial zipper paired with the BOA speed-lace closure enables quick entry and a precise, compact fit.

Ideal for sport and sport-touring riders seeking protective coverage and a streamlined look that works both on and off the bike.
