  • The S-MX 5 boot is CE certified
  • Innovative air vents at the ankle, heel and forefoot are covered with a specially designed mesh to provide unmatched levels of rider comfort
  • Large ‘throat’ profile instep and Achilles flex bellows for superior flex and comfort

Alpinestars S-MX 5 Boots 4.7 5 65 65
Pretty much what I needed These boots are very comfortable, and the ventilation works well when on the move. I haven't tried them in the rain yet. I wish there was a cinching mechanism to get them a little tighter, but I still don't fear them falling off my feet. August 2, 2016
Great fit. Very comfortable. Great fitting boot. Very comfortable. Maximum protection. June 21, 2016
Great boots I've had these boots for several months now and think I can write a review about them now. I'm a little scared that I will break the zipper when I put the boots on, but the zipper is attached by a stretchy material (forgot the name) and I don't think it will break. My boots fit nicely, but are snug when I try to zip them. I based my size choice on the EU size chart on my current shoe and not the US shoe size. This worked out well for me, but it might not work for everyone. I really enjoy the height since it will protect my shins and feet well. I haven't had to test them, but I feel safe and when I wear the boots. The air flow isn't that great, but I don't notice my feet sweating or too much air so I think it is fine. I also really like the toe slider in case I go down and that it is replaceable. I will most likely be getting these boots again when I need another pair. June 14, 2016
Great bang for the buck For the price you get a lot. Only downside is that they are kind of bulky. I had to readjust my shifter to the max to accommodate its size. Otherwise, once you get your leathers arranged correctly inside the boot, they feel great. June 14, 2016
Awesome Product This is a great boot for someone looking for an in between full on road racing boot and street boot. Extremely comfortable and very well vented. Took no time for the boot to break in. Highly recommend this boot to anyone. May 31, 2016
Can't go wrong As soon as I pulled these bad boys out of the box I was impressed. These are my first pair of boots so I was pumped to get them. Started off with a little inspection, everything felt solid and strong. Once I put them on I didn't want to take them off so i wore them for a little to kind of break them in. They feel odd to walk in at first but I assume most are at first. Once I finally rode with them I loved them even more. I felt more comfortable with riding knowing the amount of protection I had down there. It's a little difficult to feel the gear shift at first, but after a few rides or hours you'll be able to feel it just fine. Some people say they don't get much air flow but I haven't had a problem with my feet getting too hot at all. The velcro and zipper are pretty solid so don't worry about the zipper breaking off. All in all great boots, I'll definitely come back to Alphinestars for a new pair later down the road. May 28, 2016
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
