Alpinestars SMX-6 V2 Drystar Motorcycle Boots 40 Black

A waterproof, breathable, anatomically shaped boot for track and road, packed with groundbreaking features, the advanced S-MX6 DRYSTAR® incorporates Alpinestars' latest advances in boot design and development. Every component of this CE-certified boot delivers critically important performance: protective innovations, improved ergonomics, and comfort features. A newly developed boot upper incorporates groundbreaking forefoot, rear bellow, and rear calf panels for superior levels of flexibility. The main upper is constructed from advanced microfiber for durability and repeated abrasion resistance, along with a waterproof and breathable DRYSTAR® inner layer for outstanding all-weather performance. An ergonomic last provides greater forefoot aerodynamics for significantly greater control at the levers, as well as superior comprehensive foot profile, fit, and comfort. Alpinestars' groundbreaking lateral TPU ankle brace provides biomechanical support between the lateral calf/shin and ankle, offering improved structural integrity, impact protection, abrasion resistance, and flex support. The sole is constructed from Alpinestars' new, unique rubber compound for enhanced feel and grip, water drainage, and durability. Vents on the heel counter and shin guard improve comfort and reduce fatigue on short or long rides. The shin and calf guards, heel counter, shift pad, and toe slider are constructed from injected high-modulus TPU for enhanced impact protection and durability. A double-density ankle protector on the medial side is layered beneath the upper, providing protection in key areas. Built-in, replaceable sliders constructed from bi-injected TPU feature a simple screw-on design for quick and easy replacement. Groundbreaking accordion flex zones at the instep and Achilles for excellent comfort, expansion, control, and support. The internal footbed features integrated shin reinforcement for arch support and foot protection. The medial-lateral opening/closure system features a zipper on an elastic panel with a wide closure for flexibility and a secure fit every time. The entry opening is wide for easier on and off. Internal toe cap protection is layered beneath the upper for durability, improved feel, and performance. A new removable anatomical dual-compound footbed integrates EVA and elastane for performance, comfort, and support. The SMX-6 DRYSTAR® boot is CE-certified.
