Alpinestars confirms the standard V3 generation: Alpinestars SMX-6 V3 specification.
Revised flex zones and a supported ankle
The V3 upper uses microfibre with front and rear flex areas combining textile, mesh and soft TPU. The lateral brace connects the calf, shin and ankle region, while a rear TPU bridge adds structure. Try those parts as a complete system with your knee bent, checking that the support aligns with your ankle without preventing the movement required at the controls.
Entry is on the inner side through an elastic-mounted zip and hook-and-loop closure. Fasten both before judging heel retention or calf space. The screw-fixed toe slider is replaceable, so confirm the correct V3 component before buying spares. A removable footbed sits above a reinforced insole and rubber sole; assess clearance beneath your gear lever with the supplied setup. This standard version is separately listed from Drystar, Gore-Tex and Vented options. Its checked specification does not list a waterproof membrane, so establish weather requirements before choosing between them.
Protection and construction
The specification lists protection at the toe sliders, heel, ankle and shin. Check that these areas sit correctly when you adopt your riding position.
Versions and options
The checked listing links to these options: Black / White / Red Graphic, Black / White / Red, Black, Black / White, Black / Red Fluo, Black / Silver / Red. Check the selected version and available sizes before ordering; the linked price may apply to a particular option.
