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.
