Is the SP-X BOA a full race boot?

No. It is a mid-height sport and sport-touring boot with CE EN13634:2017 certification. It offers less rigidity and coverage than Alpinestars' track boots such as the Supertech R.

How does the BOA closure work with the zip?

You close the medial zip first, then turn the BOA dial to tension the lacing for a precise fit. Release the dial and unzip to take them off.

Does it fit under riding pants?

Yes. The compact mid-height shape is designed to sit under tech riding pants, giving an over-the-pant look without bulk.

How does it compare with a riding sneaker?

It adds a shin protector, ankle discs, a TPU heel counter, a toe slider and a torsion-resistant sole frame. That is more protection than most riding shoes, with similar walkability.

Is it good for walking off the bike?

Yes. The PU midsole with a double-cushioned heel and the removable OrthoLite insock are built for walking, and the asymmetric heel supports a natural stride.

One pair of SP-X BOA boots in the chosen size and color. Insoles are removable, and no extra laces are needed because of the BOA system.

What reviewers say

Owners describe the SP-X BOA as a comfortable, protective sport boot that walks well and disappears under riding pants. Most praise the fit security from the BOA dial and the solid ankle and heel support. Complaints center on the two-step closure and a narrow fit.

What people mention

FitMixedRiders find the fit secure but narrow, so wide feet may need to size up.
ClosureMixedThe BOA dial holds well, but combining it with the medial zip makes gear-up slower.
Walking comfortPraisedOwners say the cushioned heel and knit flex zones make off-bike walking easy.
ProtectionPraisedAnkle discs, heel counter and sole frame give confidence without race-boot stiffness.
VentilationCriticisedThe knit and mesh panels breathe less than expected on hot days.
