SP-X 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 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 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 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 has 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 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
SP-X boots are perfect for those sport riders looking for coverage and protection but without the full race boot, over the pant look
