The revolutionised Alpinestars Tech 7 Enduro  Drystarboot incorporates innovative materials and technology in a completely new design for a lighter, more anatomically profiled performer. This boot promotes core stability and flex via a biomechanical pivot while offering excellent ankle protection. The boot chassis has been designed to give a complete feel and optimised interaction with bike controls, while the innovative buckle system allows easy, precise closure. The boot chassis is designed with an ergonomically profiled forefoot and lower toe-box to provide more effortless shifting and improved rear brake feel and control. The upper is constructed from innovative microfibre material that is flexible and abrasion-resistant. The upper material is reinforced with PU for high water resistance, durability, and weight-saving performance. The specially designed sole provides enduro riders with superior grip, durability, feel, and a high level of structural rigidity, and a wide entry aperture gives convenience with a hook-and-loop upper closure with a TPU flap to allow a wide range of calf fitment adjustment and support. The medial-facing area is constructed from a one-piece TPU panel with a honeycomb structure for maximum grip contact with the bike and improved heat and abrasion resistance. The top rear flexion of the boot is supported around the calf by an innovative TPU sliding blade system, which dissipates friction. An ergonomic buckle system offers a secure and highly personalised fit, and innovative TPU lateral ankle protection provides a biomechanical link between the middle and bottom lateral of the boot. The instep and Achilles accordion flex zones are constructed for superior control and support, and a TPU lower shell is reinforced with a metal shank, which includes toe reinforcement for impact and abrasion resistance. The extended microfibre gaiter helps seal out water and dirt. The Tech 7 Enduro closure system includes polymer buckles plus an aluminium frame with innovative, self-aligning, quick-release closures for a custom and secure fit. Plus, all buckles are replaceable. The breathable mesh 3D liner with anti-sliding microfibre suede reinforcement on the heel area for superior comfort with soft poly-foam that surrounds the ankles and collar to offer comfort and shock-absorbing performance, plus a removable anatomic footbed. The Alpinestars Tech 7 Enduro Drystar boot membrane provides 100% protection against water penetration, and these are CE-certified to EN 13634:2010.
