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.

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.

Alpinestars SMX Plus Vented Boots 4.8 5 110 110
stylish and comfortable [Style] I got these in the Black/White/Yellow and love the colors. I get tons of compliments on them from riders and non-riders alike. [Sizing] I wear an 11 in women's or a 9.5 in men's [US sizing]. I initially ordered the 43, but ended up with the 42. Even the they are labeled as a US 8, they fit perfectly. I can easily fit these over my suit, and I am able to adjust the tightness around my calf enough that they are still ok with thin pants. If I had one complaint about the sizing here it would be that I can't adjust the fit around the calf enough, but that problem may be unique to me since I have pretty tiny ankles/calfs to be wearing men's boots. [Comfort] These were comfortable from my first ride with them, and aren't too bad to walk around in. I'm a more novice rider, and sometimes ride in regular shoes -- I have a small adjustment on shifting when I switch to these, but they are pretty comfortable and equivalent to other racing boots I've worn in that regard.

Great boots and colors are sexy So I'm not really an expert on boots. My first pair of Astars web goretex boots which were super comfy so my impression of Alpinestars were always on the great side. Then I wasted a lot of money on buying riding shoes ( more comfy ones ) and ended up selling them all. Then I bought my first pair of sport bike boots (tcx sporttour) which weren't very comfortable and wasn't vented. So, I thought maybe more protection, less comfort until I got these smx plus vented ! Super sexy, super comfy, Great protection. Easy on easy off ( ratchet on the top don't do much ). They felt broken in on day one. Very very excellent feel. I can't say more good things about it. These are just miles ahead of the other entry level boots. So from now on, I will only buy top models. ( have a pair of big D axial pro in on their way ) . If I have to say one bad thing, is even in this vented version, on my cbr I couldn't feel much air coming in. But other than that . If you need and want a great pair of boots. Get these !!!!!! July 9, 2016
Awesome Boots! These boots are extremely comfortable and they breathe amazingly well! I was surprised how much air flow I felt through them the first time I took them out for a ride. Definitely very happy with this purchase. Also - size wise I wear a 10.5 Vans and I tried a 43, 44 and 45. I thought from other reviews that the 44 would be the best fit, but the 45 was actually the better fit for me. July 6, 2016
Excellent Boots! These boots seem well made and fit true to size. I think that they will offer very good protection but I hope not to test them in that way. July 5, 2016
Got em today part 1 After 2 boots and 7 years of Alinepstars Web Gore Tex. I put them on, I was suprised how well my feet went into them. The pro version. I tryed the normal version, only for 5 minutes. They didnt feel so comfy, more skinny, higher heels. Wich led me to second thougths of getting the pro version , maybe they are little more different... But as some say, they are kind of hookey, they are like taking on roller blades. But that is an issue u cant see on the outside... My past problem before with other boots is the connection with side a to sice b wear of in a while, leaving the boot completely open if not 50% if the zipper works. My zipper failed on both boots on the web gore tex... Dunnu about the new ones... but it seemed like u dont have to thigth anything there are 3 points of closing the boots, no need to use force, just snug ure foot in. I would lubricate the plastic thing with the right compound.... As people say, feels like tennis shoes.. June 6, 2016
Awesome boots I bought this boot when I was in the process of achieving ATGATT protection. I compared numerous boots before choosing this one. As far as protection goes, this boot has proven itself. I crashed once wearing them. Crashed around 30 mph, and slid for a few feet. Ankle/toe sliders did their job perfectly and my ankle took no damage. As far as the boot itself goes, it's incredibly comfortable, fits exactly true to size, and has amazing air flow. In my search for what I was looking for, I knew I wanted complete ankle protection. Not that low boots are bad, but we all know ankle protection is a huge thing as I found out. I love that these boots have the hard protection on BOTH the inside and outside. This was big for me as far as which ones to choose. I also realize that a full tall boot like this is a track boot (which I'm not a track rider), but almost all the gear I wear on the road is track level and provides the level of protection I wish more people would wear. Yea, it can get hot and sweaty, but it's a small price to pay. The boot goes on incredibly easy, laces up fast with a speed lace, and comes off easily. I hope this helps anyone deciding on a higher end boot for various reasons including protection. I highly recommend! Note: The only problem I have had with these boots is since I wear them every single time I ride, the speedlace in one boot snapped. I contacted Alpinestars, shipped them out to them, and got both laces replaced for only $20 and the cost of shipping to them. Whole process took about a week and a half. Also, not a problem with them, but as others may have noted, they do squeak. Also, Revzilla has as many know, fantastic and speedy customer service. They are more than happy to talk on the phone with you for however long if you have product questions like I did. June 1, 2016
Great price and comfort for long narrow feet Have only rose in them a few times. But my journey for finding the correct boot has been exhausting. Having long narrow feet and smaller calfs, finding a boot that fits good is apparently quite hard. I tried 3 different pairs of Sidis, a few other brands and one other pair of Alphinestar boots before I found these. I personally think they need a insert in them, as the one that comes with the boot is quite thin and unsupportive. Sizing is a little bit off by about a half size in my experience. As far as in the bike they seem a little slick at first but I did get use to them. The shift pad is a little thick so the "feel" is a little dull. The lacing system is a nice add to support, but kind of hokey, could be a little more thought put into it. They breath very well when riding, can fee a nice breeze. Overall very pleased with the boot for the money. May 26, 2016
Great Buy I caught these on closeout and and very happy with them. I ended up needing a size smaller that I thought and revzilla switched them out no questions asked. Going 45+ these have great air flow, my feet dont sweat at all. They are really light, almost feel like tennis shoes. May 24, 2016
