Alpinestars SP-X BOA Boots - Black/Black
The Alpinestars SP-X BOA Boots in Black/Black are sleek sport boots designed to fit comfortably under tech riding trousers, offering superior walking capability. As a leading UK retailer, Moto Central is proud to offer these high-performance boots. Optimised for sport and sport touring riders, these compact, mid-height boots provide premium levels of protection and comfort both on and off the bike.
These Black/Black boots feature an upper constructed from a combination of Rideknit® material and knitted mesh, plus seamless thermo-welded parts. The lower features a TPU heel counter, toe slider, and the Alpinestars Transversal Protection Frame (TPF) on the sole, allowing for high levels of protection against impacts and bending or twisting. 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 boots have an integrated shin impact protector, dual-density ankle discs, plus TPU shift pad and toe slider reinforcement. 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® insole provide excellent walking comfort. These boots are designed for protection and 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 boots are perfect for sport riders looking for coverage and protection without the full race boot, over-the-trouser look. At Moto Central, we understand the importance of quality gear. As a major UK retailer for Alpinestars, we can order any colour or size you desire. Please feel free to enquire about the vast range of options available for these excellent boots.
