Miguel M: Best Boots on the market .... periodAug 27, 2014
Ryan B: They are %30 off at time of purchase for a good pair of boots and i do mostly of highway/fast city so normal boots don't cut itAug 25, 2014
brian s: have had three pairs of the smx boots and two pair of them have let me walk away from rather bad accidents. Last accident i hit a deer slid 600 ft( state trooper measured lol) and boots were ruined but my feet were injury free! i swear by them. just needed a new pair old ones were very weathered.Jul 3, 2014
Johnathan P: I wanted to step up from the SMX 6 because it didnt have enough protection torsionally, nor did it have any protection for the inside ankle. The closure was good on the SMX 6 but only if you have big calfs so i had to overlap the velcro and it didnt feel as secure that way.Jun 15, 2014
kevin m: fit & functionality.. reputationMay 31, 2014
Travis S: Great all around boot. I didnt want anything too expensive, but i needed the protection for track daysMay 26, 2014
DAVID W: These were extremely comfortable when I tried them on, and the level of protection in the construction seemed far above Dainese (or anyone else) in that price category - and Revzilla is $100 less than anyone else on this boot. STOKED !!!Apr 15, 2014
Steve L: My choice to buy these boots is because they were a closeout item and had great features at the time for the money. Being a non-perforated boot they are incredibly warm too. Owning these boots has brought my confidence up when riding in colder weather. I will buy a perforated boot for the summer.Apr 13, 2014
Kenneth H: Like the daytona boot, However I cant find what I like decidedd to give these a try. no as comfortable as my daytona's We'll see, been walking around the house to break them in, Kinda uncomfortable so far.Apr 11, 2014
N E: Chose this glove to obtain more protection then the short cuff style for more aggressive (track day) riding. Like the upgrades from the older version of the boot, and the price was very attractive.Apr 9, 2014
Sandro R: Reviews, style, tried in storeApr 8, 2014
Brian L: The boots are amazing! I ride rain or shine, and the basic A* boots are slippery when wet, but the soles on these grip VERY well! The boots fit a little thin, but after you get used to them and break them in, they aren't too bad.Mar 20, 2014
A R: It was on closeout at a great price. Got features at the price of a lesser model. Liked the aesthetics. Like the brand as I also bought an A*'s race suit.Mar 20, 2014
Tyler J: I liked the style, and I trust alpine stars to provide a good product. I also read up and reviews and ppl had reviewed them well. To top it off a personal friend recommended them and the price point was right fo me with the discount/sale that they were having.Mar 10, 2014
matthew w: I chose these boots because they look bad and after watching many reviews I think these boots will fit my needs the best. Being a more street rider, I do go to the track every now and again so these boots were a little more in between the two styles which seemed to work best for me!Mar 10, 2014
Daryl J: best protection for the price.Feb 22, 2014
Jonathan B: I read alot of good reviews and I like the extra protection that it has.Feb 20, 2014
robert r: These da bad boy squeaky boots on closeout, u know the new model be mo cash and wont be squeaking no mo, plus dey look rad fast and they b jam up for falling off yo ride. Anything mo bad take half da day to put on Dis some fine treads. Its stupid late I am going to bed, put my treads on the truck thanxJan 25, 2014
Nathan O: Excellent boot for the price. Even more awesome when it is on clearance. High quality leather. Excellent protection including anti-torsion ankle system. It fits well and is comfortable. The interior lace-up system makes for a better fit and peace of mind. You might be cramped if you have very wide feet but since I have medium size width, I can't say it is a fact. I doubt you will regret the purchase.Nov 15, 2013
Daniel R: These boots are the best. if you live in a hot area get the vented! also if you walk alot in them or use them alot put some better insoles in them but other than that awesome bootsNov 5, 2013
Arsim A: Protection protection protection better be safe then sorryNov 3, 2013
Chris C: I was looking for a boot that was comfortable with great protection on and off the track.Oct 19, 2013
Gary R: Got these on clearance and do not regret the decision. Extremely comfortable and quite easy to get on and off. On one boot the side screw came loose. After a quick tighten with a screwdriver, I experienced no further problems.Oct 11, 2013
Carlos A: Look amazing more protection than I've seen at this price range.Sep 13, 2013
A shopper asked:I'm a size 10, should I get a 44 or a 45?Dec 9, 2013
German Y asked:Is there any venting on the non-vented version? Has anybody used the non-vented version in 90-100 degree weather (I'm in Arizona), and, if so, how hot does it get in these boots?Jun 13, 2014
Judy H:Even though they are non perf they still have ventilation. I've rode in 90 deg weather and they're not bad, not as good as perforated but I can feel air flow threw the boot. If you watch the video of the boot you can see the exhaust vents in the heel. I don't know what the heat in Arizona is like compared to Pennsylvania but I hope this helped. By the way I love the boot, comfortable and good support.Jun 13, 2014
Bruno B:I use mine on different weather. Both on summer and winter. Temperatures ranging from 10 to 35 Celsius. On winter it's just a matter of using the right socks. On summer it gets a little hot, but nothing unbearable. Jun 13, 2014
Brian R:Non vented means no vent. I use these are track days in Florida and don't think vented or non vented matters much. They are both hot! Getting a nice pair of socks and taking them off between sessions is what we do.Jun 13, 2014
Dwayne D:I'm in Houston and I have no problems sweating in them when I'm on the track. My feet stay pretty cool with the socks I use. I did crash in these boots and they provided great protection and still usable right after.Jul 18, 2014
Chris A:Silicone oil will work--can get it from electrical supply places or either off of the internet. Relatively cheap, also. Just drip some of the silicone oil in the plastic hinges and walk around; the squeaking should slowly go away. If you cannot find any silicone oil, then furniture polish will also work since it has silicone in it. Just spray some on the hinges to make sure the liquid gets down between the hinges.Oct 9, 2013
wilmarie s:I've used them for about 3 months and found no squeaking on the ankle supports or any other part of boot. I would guess that using a grease of some sort will probably fix that for you. Oil a rag and wipe on ankle support.Oct 9, 2013
PRATAN R:I purchased Alpinestars S-MX Plus Boots size 44 EU (9.5 US). It fit me just fine. It did not feel tight at all. For reference, I wear Mizuno running shoe size 11 US (44.5 EU). Hope this helps.
I purchased this model because it specifically has ankle protection at the lowest price point when I bought them in 2013. The only I didn't like about this boot was that there is a noticeble squeak when I walk around in quiet areas such as in the workplace, at school, and especially the library. If it is outside, then it isn't an issue. Just don't count on being stealthy sneaking around in these boots. I think that newer models may have solved this problem.Jun 20, 2014
Shawn M:I would go with the larger more comfortable size as long as your foot isn't swimming around in the boot. A snug fit is important but so is comfort. If the larger size is comfortable to ride with as well as walk around in, then I would go bigger. Keep in mind a better aftermarket insole could also help to give a better snug fit if need be on the larger boot. It's always easier to fill up space in a boot then to create it. Hope this helps. I love my boots. Ps the draw string for the inner boot broke so I actually took both out. It's not really needed. Just my opinion. Enjoy and ride safe. Jun 20, 2014
James C:I had a pair of TCX half boots size 44 that fit great. But after reading some reviews I ordered size 45 in the S-MX. At first these even seemed a little tight but broke in fairly quickly and fits my foot fine.Jun 20, 2014
I bought the shoes couple of months back and I recently noticed that the one of the screws holding the multi link ankle protection system came off. How do I deal with this? Just put another screw of same size on or what? Is the boot still functional?Oct 25, 2013
G N:No big deal, the screws do come loose. I have lost one but my bike shop had some replacement screws. They were out of a different boot (phillips head screw) but the right size screw and you don't notice the different screw head at all. Also I regularly give my screws a wee tweak just to make sure that they are not loose. The other thing to do is to put them in with some Loc Tite as this helps to stop the screw coming loose. Hope this helps.Oct 25, 2013
RevZilla:This boot is designed to freely flow air, so it would allow cold air to channel through the boot in cooler temperatures. You might be able to use this boot with a Thermal Sock to help with cold weather riding.Jan 31, 2013
Mia88:It depends on where you live I suppose but yes. I wouldn't recommend air boots if it's cold outside or you could wear thick socks underneath. You will feel air along your feet though so keep that in mind.Mar 25, 2013
tsuyoshi t:I currently wear the SMX 2 short boot in a size 39. They are a bit tight in width but are OK on the bike. What size do you recommend (39 or 40)? Also how well ventilated are they, I live in a warm humid climate (Singapore)Jan 29, 2014
RevZilla:We would recommend a size 43. Based on our experience this should provide you with a proper fit if you have an average size foot. If you have very narrow feet then a 42 might be a better option.May 21, 2012
yyzryder:I thought the same thing at first but if you look closely you will find the perf and non-perf have a separate link you can open up. once you have opened the link you can use the zoom feature to see the perf holes all over the boot. Hope this helps.Mar 11, 2013
tsuyoshi t asked:I currently wear the SMX 2 short boot in a 39. Its tight but not uncomfortable. What size do you recommend in this boot? I am also looking at the SMX 6 and the SMX Plus in the closeout section. I do mainly road touring but I would like to try a track session. Also how well vented is this boot?Jan 29, 2014
I wear a US size 9 and the size 43 was a very good fit for me. I don't know if that helps you very much. As far as venting, there are two versions, the vented and non-vented. I have the non-vented and there have been times during hot humid days I wish I got the vented version, but even without the venting, it is not that bad. If you want a boot that works during the spring and fall as well as summer, I recommend the non-vented version.
Frank F:I believe that the sizing that Alpinestars uses is generally universal throughout all their gear; I can't tell you for certain, however, because everyone is different and a different boot with different technicalities may be different. I've ridden with these boots in 90-95 degree weather and it it's not unfortably hot; the ventilation could be better, but that's not to say there isn't any.Jan 29, 2014
aaron f asked:Anybody have issues with the laces cutting through the loops from repeated use and friction? That just happened to me with a different brand, so now I'm feeling cautious about boots with similar systems. As a commuter boot, how long is this lasting the long-time users? ThanksNov 30, 2013
John W:I have only used these for track days. They have served that purpose well. Had a bad crash in march of this year. Had a hard impact with the left boot. No broken bone in the foot, and the boots are still being used. (Both toe sliders were thrown off, and I broke a rib). Lace system still works fine.
Considering the aggressive foot position, I don't think I would want to wear these for daily use. They are more of a race boot. Hope this helps you in your decission. Dec 1, 2013
Gary S:I have only had my boots for a short time, so i have not had any problems with anything. I can tell you that i love the boots fit and finish, along with being totally comfortable. Great Boot so far.Nov 30, 2013
