The CE-approved Alpinestars SMX Plus v2 motorcycle boots are the next generation (version 2) of the best-selling Alpinestars SMX Plus race boots. Made from lightweight advanced microfibre upper, the SMX Plus V2 also has hyper-torsion, hyper-extension and hyper-flexion protection with dual density TPU replaceable toe slider with screw-in assembly, contoured high modulus shin plate protectors, Alpinestars' Multi-Link Control system for advanced external protection and support for ankle articulation and a wide heel counter with lateral ventilation to the ankle and is combined with a shock absorbing padded insert and self-moulding ankle protectors for superior levels of protection whilst not compromising on comfort. Flexible accordions in key areas give added movement, and strategically placed ventilation provides optimal airflow along with accordion stretch panelling at the opening for ease of exit and entry and a breathable advanced synthetic forefoot lining laminated with open cell foam for shock absorption. The shock-absorbing heel sliders are replaceable, and these also feature a micro-adjustable ratchet top closure along with Alpinestars Lace-Lock System to guarantee a quick, precise and secure closure. Available in a choice of colours.
