For superior safety and freedom of movement, the newest version of the Alpinestars SMX Plus features an innovative Multi Link Control system and high modulus TPU protection integrated into the sleek profile of the boot. An inner Kevlar speed lacing closure and micro-adjustable ratchet fastener combine to ensure a comfortable, conforming fit on both the road and track.

Unique Multi Link Control System

Alpinestars unique Multi Link Control System provides advanced support for the ankle, limiting hyper-torsion, hyper-extension and hyper-flexion as well as providing additional impact protection to the ankle and Achilles.

Premium protection

Contoured shin plate protector is injected with high modulus TPU for superior impact and abrasion resistance. Wide, ventilated, heel counter extends to the ankle and is combined with a shock absorbing padded insert and self-molding foam ankle protectors. Replaceable heel slider and external side heel slider are positioned to dissipate shock and promote sliding during an accident.

Race inspired details

Inner Kevlar speed lacing closure and a unique lateral zipper offer precise and secure fitting. Micro adjustable ratchet buckle closure on the calf lets you finely tune the fit of the boot for maximum security and comfort. Alpinestars anatomical and replaceable countered footbed provides arch support and greater feel through the forefoot.

Awesome boot!
I LOVE my Astars SMX Plus boots. I bought mine in 2009 and am just now having to replace them. I didnt own a car for 2 years so I rode daily to and from work year round with them, plus every day during the summers after that until now and i still love putting them on. They are very comfortable, sometimes i will have them on for 8+ hours a day (riding, hangin out, riding, bar hopping) and im golden. The ONLY downside (which doesnt bother me) is that the squeaking never goes away lol im used to it by now but it never really bothered me anyway. If you're looking for a great investment and great pair of boots, BUY THESE.

PROS: Comfortable, Durable, High Quality, Solid

CONS: they squeak

BEST USES: Track use, Daily riding, Long Distance Trips 250, Long Twisty Runs
