Alpinestars SMX Plus Vented Boots

The latest version of the Alpinestars SMX Plus Boots features a completely updated protection system for the heel and ankle areas. 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

Newly designed, replaceable TPU toe slider with snap-in assembly provides more coverage around the toe area. 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.

Features:

  • High-tech microfiber upper construction is lightweight and extremely durable
  • Forefoot laminated with shock absorbing open cell foam while the ankle area has a highly breathable lining for improved comfort
  • Large front and rear asymmetrical accordion zones are optimized to maximize flexibility for superior comfort and safety

Awesome Great fit, love the inner boot laces, really pulls your heels down while allowing you to flex your ankle. Venting is ok, they're a little warm. Very solid, good solid heel cup and lateral ankle protection. July 9, 2015
Good...but can be noisy I've worn these boots for a little more than a year now - and close to 7,000 miles. Overall, great boots that feel very protective. I especially like the inner bootie. There's no way these things are going to come off in a crash. Despite the high level of protection, they're still reasonably comfortable to walk around in. I've hiked 5 miles in them, after riding for 5 hours straight, and my feet didn't complain too much. Just be warned - because the multi-link ankle protector is on the outside of the boot - they can be a little noisy when you walk. It's a trade-off for the extra comfort and protection. Just don't wear them to any funerals. Also - don't get caught in the rain with them, unless you have some sort of rain covers. July 3, 2015
Not much need of a break in. After owning a set of Alpinestars GP Pro boots for the better part of 20 years. I was in need of a replacement set of boots. I found the smx plus boot was a great choice for me. I had tried on many other boots. Sadici, SPIDI. But could not find a boot that fit my larger than avg ankle and wide foot. I am 6'2" @210 and wear a size 12 dress and work boot. I found that the size 46/11.5 fit me perfectly. The only thing that I need to get used to is the fact that the distance from top of shifter toe to bottom of boot is a bit thicker than I am accustomed to so I need to make a few adjustments to my shift lever. This is not a problem it just a matter of current boots providing better protection not than they did 20 years ago. Now speaking of the boot itself. Zero squeak, very easy to take on and off and most of all zero break in. I was able to ride without any fatigue. And I wore them the entire time I was working on a buddies bike 5+ hours without thinking about the fact that I was in a set of race boot. Of special note. I was very seriously considering the TCX boot. However I noticed that the heal of the boot is on an angle and its those little things that can make or break a boot when on the track or on the street as far as comfort and control on the bike.

Love these boots! I'd originally gone the Sidi route (because just look at them), but found them too narrow and uncomfortable to walk around in. These A-Stars were perfectly comfortable right out of the box. Nice and flexible when you need it, rigid when you don't. The inner boot is probably my favorite feature since it allows you to adjust how snug the boot feels. Air flow is good for a non-perf boot. My feet never got hot while riding for several hours on an 85 degree day. I generally wear a 9.5 shoe and the 44 was spot-on. July 1, 2015
Awesome! Really good product! Really great boots! If you're looking for comfort and beauty, that's for you! February 16, 2015
Just do it I purchased this boot locally. I can't say enough good things about it. I've done about 300 miles on this boot in the last 3 days, and today wore them for about 12 hours without discomfort. I was not expecting that. I have a pair of HD-ish boots that I love and have had re-soled a couple times, so they're broken in and exceedingly comfortable; but they lack real ankle support and can't touch this boot in terms of features. I wear wool motorcycle socks with this boot and even with weather in the 80's and extended wear time, they're very comfortable. I'm sure they're not even broken in yet. I'm more of a commuter and sport enthusiast than anything else, and I'm very happy with this purchase. When you hold this boot and the SMX 5 in your hands, there's just no comparison.

Feel broken in right out of the box! I was looking for a boot with plenty of protection for track days, but yet would be comfortable enough to wear on the street for long spirited rides where walking throughout the day may be involved. These fit the bill perfectly! Aside from a test ride on my work commute, about 30 mi each way, my maiden voyage with these was on WI's infamous slimey crude run. For us this involves about 400 miles of riding with lots of walking at each of the stops looking at all the wonderful toys people brought out to play. I had the boots on for over 12 hours straight, on and off the bike, and my feet never complained once. I haven't crashed in them, but the protection seems very sufficient with minimal bulk. The internal booty provides a great fit. I originally bought a pair of Sidi and, though they looked beautifully crafted, they just didn't feel right. Returned for these a* and couldn't be happier; thanks revzilla. (The Sidi's were sexy though...lol) October 19, 2014
Fit well right out of the box. A little narrow, but that is my foot. Took them to a track day with only about an hour of walking around the house in them and they were very comfortable. I have a wider than normal forefoot and so they were a little tight on one foot - god works in mysterious ways and my feet are about a half size different, so not everything fits in the way of foot coverings, but I like these and would say they are very satisfactory. Hope I never get to be an expert on how they hold up in a crash. No time on them to judge durability, but they seem well made. I am 66, have ten bikes now, more on the way, and owned over 40 since 1965. Revzilla makes is so much easier to buy and understand than in the old days. September 8, 2014
