Alpinestars SP-X BOA Boots – Sport Riding and Touring Footwear for Men, Black, EU 45

The Alpinestars SP-X BOA Boots are engineered for sport and sport-touring riders seeking a combination of protection, comfort, and style. These boots feature a sleek, mid-height design that fits seamlessly under riding pants, offering a streamlined appearance suitable for both on and off the bike. Crafted from a blend of Rideknit® material and knitted mesh, the upper provides a flexible yet durable structure with seamless thermo-welded parts for enhanced durability and reduced friction points. The innovative construction ensures a secure fit while maintaining excellent breathability during long rides or walks. The lower part is equipped with a TPU heel counter, toe slider, and the Alpinestars Transversal Protection Frame (TPF) on the sole, delivering high-impact resistance and stability. The asymmetric back heel design promotes natural stride and improves off-bike walking comfort, making these boots versatile for various riding scenarios. For added safety, the SP-X boots include an integrated shin impact protector, dual-density ankle discs, and reinforced TPU shift pads and toe sliders, providing comprehensive impact absorption and protection against twisting or bending injuries. The comfort features are equally impressive, with knitted flex zones in the front and back that allow for natural movement, complemented by a PU midsole with a double cushioned heel compound and a removable OrthoLite® insock. These elements work together to offer all-day comfort, whether riding or walking. Ease of use is achieved through a medial zip combined with the BOA speed lace system, enabling precise, quick, and secure closure for a customized fit. The SP-X BOA Boots are an ideal choice for sport riders who want reliable coverage and protection without the bulk of a full race boot, providing an over-the-pant look with premium features for versatile riding conditions.
