Alpinestars S-MX 5 Vented Boot 4.8 5 56 56
CL Purchase, Well worth the upgrade CBR XX Blackbird 2004 I have only worn these once so far. I replaced a cheap pair of boots that were fine--just, well cheap and needed to consider my boots (feet/ankles) like I do my gloves, jackets, pants and helmets. The old ones (Xelement) were better than tennis shoes. RF-1100, technics jacket, pants and speedster gloves begged for a better option. I found a pair on craigslist that were literally worn 5 times (he's out of riding--got a kid) and there is another pair size 12 in like condition still available. Each were only $100. I'm so glad I did it. The only issue for me is venting-- I've ridden in snow, rain as well as the heat. I rode with them in 20+ degree weather and noticed a slight flow. I carry the booties for the extreme weather. I'll need to get a WP pair. At speed (I'm not saying) my old ones with a velcro on each side opened up when I needed to stretch-out a leg kink on a ride in October to upstate New York (900 mile round trip with the return trip having 2.5 hrs of snow). The boot acted like a speed brake. Not cool. So far, I'm impressed. New beats worn, but no so stiff like the buckle Alpinestars I tried on earlier this year--not to mention I am more of a sport/tourer. My last two bikes were CBR 1000F's--one jetted/mild mods. These SMX-5's do seem a little roomy in the foot and firm/snug in the ankle so fitment might take a few minutes. They also are new and need break-in. I've ridden as much as 10,000 miles in a year and zero in others. I've only had the Blackbird a few months, but I'll add more comments later if something is worth it after some real miles. Sorry Revzilla for the CL ad. Not my boots to sell. Sorry, too, you missed this sale. But I'll be spending with you soon, I'm sure. Thanks for the informative videos. January 18, 2016
Glad I got these! Now I know why these are so popular. Super comfy but feel secure as well. Not much ankle reinforcement or protection so I don't get to aggressive on turns and such in these but a great commuter boot. Fit like regular boots, might be a little large in the toe. Can't really feel any airflow until temps drop below *50. Been wearing these daily for months and don't have problems as others state such as material coming off the toes but I'm careful when "walking" my machine when in traffic/parking...SMX-5's still in fantastic shape!

excellent boots I have had these boots for a few months now and have put on about 1300miles with them. I wear size 10.5 shoes and I bought size EUR 44, US 9.5. they fit perfect. they were comfortable out of the box, both on the bike and walking around. side zipper and Velcro on the side is great. no laces or bs to deal with. just slip them on, zip them up and done. they breath very well. 90deg plus days no problem at all. I rode last weekend for a few hours in low 50deg temps and they were alright and I had just normal socks on. with warm socks I think these boots would be fine in 40deg temps. October 30, 2015
Saved my feet! I've been in 4 lowside crashes, not that I'm boasting, and I've worn the SMX-5 boots through all of them. They were 30-50mph crashes where it involved loss of traction, a hard impact on the side of the body and a 20-100ft slide. The only injury I sustained to my feet was at maximum a twisted/sore ankle, but not bone injuries or lacerations. These boots are a bit over kill for wearing everyday on the street, but the level or protection you get is awesome for the money you spend. After getting roughly 200-500 miles of riding and use they really break-in and become decently flexible. Only nit pick I have about them is that they don't flow air all that well, so in-turn they become a little hot and sweaty in the summer. Final thoughts: These boots saved my feet and I can't thank Alpinestars enough. Going through 2 pairs in 4 years I'm extremely pleased with them. October 21, 2015
Excellent protection and comfort I've been riding with these boots for two years now and they are my go-to riding boot for just about any situation. They are extremely comfortable, although not really meant for wearing all day. I feel very protected, much more than when I'm wearing my technical sneakers. The zippers, leather, and velcro are still in great shape. They work well in the summer, but in the winter I wear them with some thick socks. Highly recommended April 30, 2015
Long Term User Review - A Must buy I've been using this boot for about 4 years now. After many many miles, these have held their own. Velcro & zipper on the side still work. Fit is great. Durable. I have a wider foot than most. I'm finding Alpinestars have a better fit than others. I'm a very satisfied with the design, build quality after these many years. April 19, 2015
Birthday present This product is excellent all around, I bought them for my boyfriend. The sizing chart helped me find the perfect pair. He has worn them several times now and raves about how much he loves them. They are comfortable with excellent protection. April 6, 2015
Great purchase! I bought these for my boyfriend and he seems to love them. They look really nice, great quality and seem to be good protection. He wears a size 13, so I ordered the size equivalent to a 12.5 since 13 isn't an option. He says they fit great though! December 29, 2014
