The Alpinestars Supertech R Boots combine an advanced microfiber upper with protective construction, flexibility, and a secure closure system. The front flex area uses soft microfiber to support abrasion resistance and natural forward-and-backward movement, while flexible accordion microfiber at the Achilles and strategically positioned accordion zones enhance mobility.

Protection is provided by a contoured high-modulus shin plate, an evolution of Alpinestars’ Multi-Link Control system, and protective ankle articulation support designed to limit hyper-torsion, hyper-extension, and hyper-flexion. The boots also include Achilles impact protection, a dual-density TPU replaceable toe slider with screw-in assembly, replaceable heel sliders, and an external side heel slider positioned to help dissipate and absorb shock.

Ventilation is integrated through TPU airflow construction and positioned ventilation areas in the heel and shin. A wide heel counter extends to the ankle and combines lateral ventilation with a shock-absorbing padded insert and self-molding ankle reinforcement. The advanced synthetic forefoot lining uses open-cell foam for shock absorption, while breathable lining in the ankle and leg areas supports comfort.

The Alpinestars Lace-Lock System, inner instep speed lacing closure, lateral zipper, and hook-and-loop zip-pull keeper provide a precise and secure fit. A micro-adjustable ratchet top closure stows the tab end, while the anatomical, replaceable contoured EVA footbed provides arch support and forefoot pedal feel. The durable sole features evenly textured rubber for consistent grip. This black, magenta, white, and yellow boot is sized US 12 / EU 47.
