Description
The SP-X BOA Boots are a sleek sport boot designed to fit under tech riding pants and provide superior walking capability. Optimized for the sport and sport touring rider, the SP-X BOA Boots are compact, mid-height boots with premium levels of protection and comfort on and off the bike. The upper is constructed from a combination of advanced microfiber, ultra-soft Rideknit® material and knitted mesh, plus seamless thermo-welded parts. The lower features a TPU heel counter, toe slider, and the Alpinestars TPF Transversal Protection Frame on the sole, allowing for high levels of protection against impacts and any bending or twisting. Additionally, the sole also features an all-new design with an asymmetric back heel to facilitate the rider’s natural stride and promote off-bike stability.
For protection, the SP-X BOA Boots have an integrated shin impact protector, dual-density ankle discs, plus TPU shift pad and toe slider reinforcement. And for comfort, the knitted areas on the front and back flex points offer great freedom of movement, while the PU midsole with integrated double cushioned heel compound and removable OrthoLite® insock, provide great walking comfort. In and out is facilitated by a medial zip combined with the BOA® Fit System for compact and precise closure. The SP-X BOA Boots are perfect for those sport riders looking for coverage and protection but without the full race boot, and an over the pant look.

Frequently asked questions Hide FAQs
How should I choose my size for the SP-X BOA® Boots, and how is the fit adjusted?
The SP-X BOA® Boots in Black Black are listed in EU sizes 36–48. Compare your measurements with the Alpinestars footwear size guide and check the fit with your intended riding socks rather than assuming your usual casual-shoe size.
The side BOA® Fit System provides precise closure adjustment, while the medial zip facilitates entry and exit. These features refine the fit but do not replace correct size selection.
Are the SP-X BOA® Boots waterproof or ventilated?
The SP-X BOA® Boots are listed as ventilated footwear. Their upper combines advanced microfiber, ultra-soft Rideknit® material and knitted mesh.
No waterproof membrane or waterproof rating is specified for this model, so it should not be treated as waterproof footwear when choosing boots for wet-weather riding.
What CE certification and protection do the SP-X BOA® Boots provide?
The SP-X BOA® Boots are CE-certified to EN 13634:2017, the standard for protective motorcycle footwear. Their protection package includes an integrated shin impact protector, internal dual-density ankle protection, a TPU heel counter, shift pad and reinforced toe slider.
The sole incorporates Alpinestars’ TPF Transversal Protection Frame to help protect against impacts and excessive bending or twisting. The supplied specifications do not state the individual numerical EN 13634 performance levels.
Do the SP-X BOA® Boots fit under motorcycle riding pants?
Yes. The SP-X BOA® Boots have a compact, mid-height profile designed to fit under technical riding pants. Their streamlined upper and compact closure suit sport and sport-touring riders who want boot coverage without a full-height race boot.
Check that your riding pants’ lower-leg opening accommodates the boots comfortably, particularly when seated on the motorcycle.
Are the SP-X BOA® Boots designed for walking as well as sport-touring rides?
Yes. The SP-X BOA® Boots are designed for road sport and sport-touring use with walking-focused features. The rubber sole has a walking roll and asymmetric rear heel to support a natural stride and off-bike stability.
An integrated PU heel midsole and dual heel cushion pads provide cushioning, while knitted front and rear flex areas support freedom of movement on and off the bike.
