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 speed lace 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.

    Fantastic footwear

    Posted by Charles M on 28th Sep 2026

    These boots are pretty awesome. Comfortable, walkable, and don't make you look like you're about to attempt a moon landing. Pants can be tucked-in or worn over. Looks great in either scenario. I needed some boots that would work for daily commuting, but also accommodate more "sporty" riding as well. They are a jack of all trades. They don't look like typical touring/ADV boots. More like sport boots without the big shin guard. Wouldn't use them on the track (a bot too flexible for that), but they're fantastic in just about every other scenario. For reference, I wear size 12 in dress shoes/boots and sometimes 13 in sneakers - which means I'm probably a true 12.5 foot size. I bought these in 46 and they are perfect.

    Awesome Boots

    Posted by Charles M. on 23rd Sep 2026

    I don't write reviews often. However, these boots deserve a shout out. I wanted a set of tall boots for daily riding/commuting that weren't as rigid as race boots - and I also didn't want the typical chonky touring boots that make you look like you're attempting a moon landing. Anyway, these check all the blocks. They are sleek, comfortable, and walkable - and they look good (for a moto boot). Jeans/pants will fit over them or they can be tucked - either way works great. These boots check a lot of blocks for a lot of different situations. I'd say the only bummer is that the toe sliders are not replaceable. However, if you're dragging toes, these aren't best choice for that type riding - and that's not why I bought them. They work fantastically in the 99% of other riding situations. So, if you want a boot for daily riding/commuting, with a dash of sporty/spirited hooliganism, these check the block. Anyway, I typically a size 12 in dress shoes/boots - but a 13 in sneakers. So, I'd say my foot is a proper 12.5. I bought a size 46 and the fit is perfect. My feet are slightly wider than a D - probably an A, and not an AA width. Hope that helps. If you're on the fence, I highly recommend them! They will be getting A LOT of mileage from me
