Designed in black for a streamlined appearance, these boots feature a lightweight microfiber upper with strategically placed stretch and accordion zones that support natural forward, backward, and lateral movement. The front flex area improves abrasion resistance, while flexible microfiber at the Achilles and large asymmetrical accordion panels enhance riding comfort and mobility.\u003c\/p\u003e\u003cp\u003eProtection is provided by a contoured high-modulus shin plate, Thermoplastic Polyurethane (TPU) components, and Alpinestars’ Multi-Link Control System. This external ankle protection system supports ankle articulation while helping limit hyper-torsion, hyper-extension, and hyper-flexion. The system also contributes to Achilles impact protection. Replaceable dual-density TPU toe sliders, heel sliders, and an external side heel slider help protect key impact areas and are designed to dissipate energy and promote controlled sliding during an accident. A wide heel counter, shock-absorbing padded insert, self-molding ankle reinforcement, and heel and shin ventilation areas add support and airflow.\u003c\/p\u003e\u003cp\u003eThe Supertech R uses an Alpinestars Lace-Lock System with an inner instep speed-lacing closure, lateral zipper, and hook-and-loop tab to provide a secure, adjustable fit. A micro-adjustable ratchet top closure keeps the upper firmly positioned. Inside, the advanced synthetic forefoot lining uses open-cell foam for shock absorption, while breathable ankle and leg lining improves comfort. The anatomical, replaceable contoured EVA footbed provides arch support and pedal feel, and the durable textured rubber sole delivers consistent grip. These boots fit riders seeking race-focused protection and mobility in US 9.5 \/ EU 44 sizing.
