Alpinestars SMX Plus Gore-Tex Boots 4.3 5 9 9
Comfortable boot I was looking for a track day sport riding boot that was waterproof and I found it. I tried a lot of the other brands that did not fit my foot type or had less protection. I am 6'1" tall with an 11 size shoe and narrow foot. I like the internal lace system, that allows me to adjust the tightness based on the sock type. I recently used these for a 6 day ride in Florida. My feet did not sweat in the 85 deg heat. The boot is very comfortable and flexibility to get under the shift peddle. April 26, 2016
Race Protection meets Gore-Tex This boot is over-kill for my needs. It's a race boot with waterproofing. That's why I love it. My feet, ankles, and shin feel well protected in it. With the speed lace, velcro-ended zipper, and ratchet, this boot is as secure as possible. It can be really tightened down to fit underneath riding pants, or made loose enough to put pants inside of them. I have 11.5D size feet, and a 46 fits well with a medium-thick sock. My feet have been comfortable under 40 degrees and above 60 degrees. Maybe when we have full on summer they will get a little hot, but you have to make tradeoffs to get waterproofing. One gripe is with the toe slider. I took one off due to curiosity. It was difficult but putting it back on was borderline impossible. It's a push-fit, so you have to support the inside of the boot will pushing as hard as you can against the slider. Never doing that again. March 1, 2016
Disappointed, did not meet my expectations I know this review is counter to all of the other reviews for the boot; in fact it was all of the other reviews that helped convince me to order these, however.... I'm shipping these back to Revzilla and I will try something else. I had very high expectations when the shipment arrived at my house, however I was disappointing because I expected these boots to be more rugged and of a higher quality overall, especially at the $450 price point. I ride a Ducati Monster and do a fair amount of miles on rides that include highway, and secondary roads. So over the past year I've been seeking to upgrade my protective gear to account for the fact that I am spending long hours over many miles on my bike and want to avoid a foot crush injury if I happen to go down. Currently I own a pair of AXO Freedom GT Waterproof boots, and I have rated these a fantastic boot, at a great low price; I love them. The AXO boots have good protection however, I felt I could find something that offered a bit more heel and ankle protection, and maybe some torsion resistance to prevent severe injury. The Aplinestars MX Plus I do not consider to be better than my AXO which provide stiffer toe box and shin protection compared to the Alpinestars. And, the AXO maybe just as good for heel and ankle protection compared to the Alpinestars while being less than half the price; I paid just $100 for my AXO on a discounted sale. I suspect that Alpinestar paid the Gortex royalty fee and ultimately forced them to skimp on the rest of the boot to manage price point. What I did not like about the MX Plus: - The ratchet style clasp is extremely flimsy, almost useless. - toe box does not seem protective enough - ankle protection is skimpy and is easily crushed - boot can be twisted with little energy - shin protection is thin and crushes way too easily - Overall plastic seems to be of low protective quality What I liked: - Gortex lined - True to size fit Side by Side, I'll stick to my AXO Freedom GT WP August 22, 2015
Good Boot I purchased these boots to update my aging and discontinued Alpinestar Supertech Tour boots. I will often give up comfort to gain protection and had initially narrowed my choices down to the Daytona Road Stars and the Alpinestar Toucan boots. I found the Daytona's to be less protective and comfortable than my Dianese TRQ Tour boots which I use for commuting and though I wanted to love the Toucan boots they really were too bulky for my street bikes. The limited feel and space for shifting with the large size of the Toucan caused me to pass on the Toucan. I gave these SMX Plus Gore Tex a try and they provided a good blend of protection for the ankles, foot and shin while maintaining good feeling with the shifter and brake pedal. These are boots I'll be keeping for the next few years. The boots are expensive and are not beautiful but the number of boots which are really waterproof, have good ankle, foot and shin protection which are not massive boots more appropriate for off road adventure riding are few and far between. Most of the comfortable street boots are comfortable because they give up some protection. For me these boots gave up the least amount of protection while remaining comfortable enough to feel the foot controls of the bike. March 31, 2015
Great boots Very happy with these boots. The fit on my size 11's is great - roomy in the toe box and with the lace-up system they snug right up without feeling tight. The lining is very soft on the front of the ankle and the whole boot is really comfortable on the bike. I'm recovering from a foot injury (sesamoiditis) and these boots are a big step up in comfort from my old riding boots. The sole is rigid enough to prevent excessive pressure in the arch of my foot but they're also flexible enough to not hinder operating the controls. I'm very impressed with these boots and glad to have spent the money - they're well worth it. July 28, 2014
Great boot I commute in these boots and wear them off the bike as well. Although I have no plans to go to the track any time soon, I still want a lot of protection on the street. Perhaps a bit overkill for commuting, protective gear is very cheap insurance in comparison to the pain, lost time, and medical costs from an injury. I have not tested the Gore-Tex in a significant downpour but I have stayed dry in a few drizzly days. I am impressed at how much the Gore-Tex allows my feet to breathe preventing sweaty clamminess, even when off the bike. I don't notice significant airflow as one might expect in a heavily vented boot but there is enough to keep me perfectly comfortable. These boots are also quite comfortable while walking around. I imagine these are as close to tennis shoe level comfort that you can get in a track boot. However, I plan on changing into street shoes from now on as the boot sole is not made for extended walking and is starting to show some wear. I got the squeak after walking around for a day but a few drops of silicone spray seems to have fixed that. The speed lacing system is easy to use and provides a glove-like fit. I have not had any problems with the laces cutting through the eyelets in the liner, but I don't pull very hard on the laces. You don't need much to snug them up so it shouldn't be a problem unless you're yanking on them. I originally purchased the Dainese TRQ-Tour Gore-Tex boots and did not care for them at all. The footbed was uniform but too snug for me. However, from the ankle up, the boot was very loose and the top of the boot dug into my shin. Having a background in podiatry I cannot see how the TRQ-Tour would provide any meaningful ankle joint protection. The SMX Plus boots are comfortable, appear to provide great protection, and are race stylish. The only downside is the price but then again, it's a lot less than foot surgery. May 28, 2014
Perfect boot for protection, comfort, and waterproofness If you want a comfortable boot you can hike around in but want great protection this is it. Add on that the gortex breathes so no sweaty feet and it stays waterproof. I love these boots. Mine have been tested in heat and cold and in pouring rain. They run just a size big. I'm a 42 normally and got a 41 in these. Revzilla allows returns so get 2 sizes and return what doesn't fit. BMW R1200R September 13, 2013
Usual excellent quality from A'Stars Love the "custom" fit that the speed lace system provides. The boots have a good feel for the pegs without letting them dig into your feet. These replaced a set of SIDI Vertigo Rain boots that didn't provide enough room to move my toes up and down, thus causing some discomfort, and didn't hold my foot in place because the ankle area was too loose.
