This black, white, and red boot is sized for US 8 \/ EU 42 and features an advanced microfiber upper designed to reduce weight while providing reliable abrasion resistance and natural movement. Soft microfiber flex zones at the front, Achilles, and accordion panels support forward and backward mobility without sacrificing protective coverage. Strategically placed ventilation areas in the heel and shin help promote airflow during demanding rides.\u003c\/p\u003e\u003cp\u003eProtection is built around Alpinestars’ Multi-Link Control system, which provides external ankle support while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The contoured high-modulus shin plate and reinforced ankle construction help protect against impact and abrasion, while the wide heel counter, padded shock-absorbing insert, replaceable heel slider, and external side heel slider help dissipate impact energy. A dual-density TPU replaceable toe slider adds coverage to the outer toe area and can be serviced when worn.\u003c\/p\u003e\u003cp\u003eThe Supertech R uses an advanced synthetic forefoot lining with open-cell foam for shock absorption, plus breathable lining in the ankle and leg areas for comfort. The anatomical replaceable EVA footbed provides arch support and improved pedal feel. Closure is secured with the Alpinestars Lace-Lock System, an inner instep speed-lacing closure, a lateral zipper, a micro-adjustable ratchet top closure, and a hook-and-loop tab that secures the zipper pull.
