Alpinestars S-MX 5 Boots 4.7 5 59 59
Great boots at a good price Boots are comfortable and look decent. I have not had the opportunity to test how much protection they offer, I hope I never do. They seem solid, I don't doubt that they would hold up in a accident. It does take a while to get the feeling for shifting as they a quite a bit stiffer than the shoes I was wearing. All in all good boots. Don't hesitate to buy. May 3, 2016
I'm hard to impress, and these are good to go! I'm a bit of a cynic, and find most things to be a disappointment. These were part of my first order through revzilla, and this site and the product have restored my faith in quality online shopping. The boots fits exactly as the sizing chart suggests. They are aggressive looking, comfortable out of the box, and are very well made. (don't feel cheap at all). Definitely worth the money! April 12, 2016
I like these Boots just came in. I normally wear a 10.5 in everything these were a 44 per the recommendation on the site and its spot on fit perfect. Im wearing them around the house to break them in and ill probably hit them with some kind of leather protect-ant later but so far so good! They look pretty dope. February 22, 2016
A Good Starter Boot It fits well and is easy to put on and take off. It does get warm due to little to no air flow comes trough the boot.. February 17, 2016
Alpinestars SMX love these boots, super comfortable and easy to put on. from road racing to taking a long ride on the weekend they will do both. highly recommend for any type rider needing protection but also wanting a comfortable boots June 11, 2014
quality boot These live up to expectations for an Alpinestars product. Good quality construction, decent styling. The most important fact to mention is the fit. I have a slightly wide foot, and have suffered Morton's Neuroma in both feet so I can not tolerate having the metatarsals compressed. Old fashioned leather boots stretch, but modern Lorica/plastic boots are not going to mold to your feet. Italian boot makers make some of the best motorcycle boots out there, but sadly they do so using a skinny Italian last. Sidi and Gaerne are simply too narrow for me. These SMX5s are typical for Alpinestars: the forefoot is just barely wide enough, length is right, but heel cup and instep are sloppy & loose fitting. This has been the case for me in the previous two sets of Alpinestars boots I've had as well. The only boot I've tried which was wider was the Coretech Latigo, but those are grossly inferior. The ventilation in the SMX5 is not all that substantial, and I've had a strange experience where the instep hangs up on my footpeg as I move the left foot to shift. Still, I like these boots. I'd definitely recommend them for someone who wants something a little less armored than a race boot, but still protective. They go under jeans, and don't have articulated plastic armor that creaks when you walk. March 17, 2014
Great boot One of the best boots out there. I strongly recommend these boots! They fit great and are super comfortable. February 7, 2014
Ahhh yeahhhhhhhhh Finally got myself a decent pair of riding boots. I've been looking around for awhile now. I was tempted to go with the MX-2s but thought for the price difference why not going with something more protective. Still breaking mine in at the moment but looking forward to using them this summer. January 21, 2014
