The Alpinestars SP-X BOA Boots in Black/Silver are perfect for sport riders who want a sleek boot that fits comfortably under tech riding trousers and is great for walking. These compact, mid-height boots are designed for both sport and sport touring riders, providing excellent protection and comfort on and off the bike.

The upper part of the SP-X boots is made from a blend of Rideknit® material and knitted mesh, along with seamless thermo-welded components, ensuring durability and flexibility. The lower part features a TPU heel counter, toe slider, and Alpinestars Transversal Protection Frame (TPF) on the sole, which offers high levels of impact protection and resistance to bending and twisting.

The boots also have a newly designed sole with an asymmetric back heel to support a natural walking stride and provide stability when off the bike. For added protection, the SP-X boots include an integrated shin impact protector, dual-density ankle discs, and reinforced TPU shift pads and toe sliders.

Comfort is key with these boots, featuring knitted areas at the front and back flex points for better movement, along with a PU midsole that includes a double cushioned heel compound and a removable OrthoLite® insole for a comfortable walking experience. Getting the boots on and off is easy with the medial zip and BOA speed lace system, which ensures a snug and precise fit.

Ideal for sport riders seeking great coverage and protection without the bulk of full race boots, the SP-X BOA Boots offer a stylish and functional option.
