Good product, good Cost/Benefit relationship Nice looking boots, overall good protection on toe and heel, poor protection to the instep, (upper section of the human foot between the ankle and the toes). very basic protection to the shin and Aquiles Tendon. Personally I did not like the high glossy finish heel. but maybe with a sand. Very good ventilation and confort. Very good purchase April 28, 2014
Great Value So far so good, had the boot for half a year already. Very durable, great value for the price. Comfortable everyday boot, easy on easy off with just a zipper and velcro. Could have more protection for the shin area but for the price it is unbeatable. I also have a pair of SIDI Vortice boots which I love but is a pain sometimes to get on and these are my go-to everyday boot. Vents decent but can get hot at times. April 14, 2014
Comfort and durability I have purchased these boots just in time, one week after my purchase I wrecked and the boots go a little scuffed but they held their ground and are very comfortable. March 17, 2014
Disappointing Quality While the fit for my size 12 feet was just fine, I was really disappointed by the quality of these boots, even at this price range. The leather, the zippers, and the hardware in particular were a letdown. These boots hardly felt any more protective than a solid pair of work boots, the zippers required a lot of effort to move and stuck frequently, and the plastics vents, shin guard, and heel cup felt purely cosmetic rather than functional. I would recommend passing over these in favor of something a bit better equipped. October 10, 2013
Good warm weather boots I'm a size 11 US, have a pair of Ridge boots in EU 44 that fit perfect. Ordered a EU 44 in these and are a little snug but not enough to go up to a EU 45. Fits similar to a US 10 1/2 on an 11 foot. Has not been a problem on the bike but would not want a walking shoe this snug. They do break in well, and would prefer a snug fit for riding rather than a lose fit. While these are not race boots (don't expect that level of protection) they are very comfortable and protective street boots. Love the air flow at speed, a very nice feature for warm days. April 23, 2013
A little disappointed I got these boots wanting to move up from ordinary work boots to get some extra protection, sadly it didn't have much more. There are no hard parts over the ankles, the heel area just as reinforced as my work boots and the shin protection isn't even hard! it's a soft easily bendable plastic material! The fit is also awkward. It's very narrow on the foot but on the area hugging the ankle it's a bit looser. I also wish that this boot only had velcro at the top. The bottom area does nothing but get in the way and give the boot an awkward shape. The things I liked about the boot though was that the sole wasn't too stiff, making it easy to walk in, the reinforced toe box, the grip you get from the sole, the venting, and the overall look. However I don't think this worth $200. Spend the extra $15 and buy some Sidi fusions. November 3, 2012
Great hot weather boot This boot actually performs how it was advertised. While riding you can feel the air circulating around your feet, the vents work fantastically and you stay comfortable no matter how hot it the ambient temperature may be. I prefer to wear boots year round but sometimes sacrifice safety and control by wearing sneakers due to heat but now with these boots I can stay comfortable and not have to sacrifice safety. Before riding I tuck my jeans into the boots so not to block the vents and untuck when stopped and have a great looking, comfortable boot to walk around in. May 29, 2012
Minimal plate protection good leather construction. Full grain cowhide boots made with 3/4 zipper up inside and the upper is held closed by a large panel of velcro. As a pure leather boot., these pfovide basic fit taht quickly molds to your foot like good leather should. They breath very well through the shin pores, and ankle port. The heel cup and outer vinyl provide good protection for the heel, and the price is good, but a serious off roader will need bettter traction from the sole and much more shin/ankle protection. If you're 90% street, they'll be good summer boots. December 14, 2011

karen k: The size depends on whether your feet are small/narrow or med./lg. in with. I have a sz. 9 / med. foot. I got the 7.5 & they fit fine! I wear med. wool/silk blend socks. I wore a shorter sock w. them for the 1rst. time... & if you do a lot of walking... the boot will rub sore places on your leg. so wear long socks! the shaft part of the boot was really stiff at 1rst... I wish they were about 2" shorter, but you would loose some shin protection... but, you could walk easier. Apr 4, 2014

Jim P: I believe it's just bigger in size. You can always order your size in men's and see how it fits you. I personally love these boots.. I have a pair of SIDI Vortice racing boots as well. Normal every day wear these boots provide good airflow and decent protection in critical areas. Apr 4, 2014

David N: Not that I know of. They're not gonna look real stylish either way. But as long as they fit well, they should do their job just fine. Which is to keep your feet as comfortable and as safe as possible while you ride. I wouldn't recommend these if your wanting to look good or be especially comfortable if you're planning to wear them off the bike for extended periods, once you reach your destination ( at work etc).

A shopper asked: I'm from Australia, and it seems that we have the Hydrosport but not the ST Vented here. I have tried on the Hydrosport in a store, but need to know whether I should be buying the same size (EU 44) in the ST Vented. Oct 2, 2011

AliB: The sizing of the Alpinestars Hydrosport and the Alpinestars ST Vented should be the same. They appear to be nearly the same boot, and both use the same sizing chart. Oct 14, 2011

Stan Z.: Don't hesitate. They'll fit the same. A-Stars are very consistent in fit even from half boots to boots. Nov 27, 2011

A shopper asked: Would love a direct comparison between these three similarly priced vented boots if anyone has actually tested all three of them. I would love to test them all, but I'm not made of money... Just looking for the best air flow possible in a full length, well constructed, and decently protected boot. Jun 1, 2011

Mark C: I actually bought both the Canyon and Clever Air boots at the same time for a road trip. These do not vent at all when compared to the Clever Air's. The Canyons are very well constructed and so far have kept me very dry during a few hour downpour. But I wore the Clever Air's most of the time during the 8 day trip as they much more vented and I preferred that during the high 90's temps.

Just be aware that the Airs do not provide any water resistance, so if you have a full fairing on your bike and your feet are fairly covered, you may not care much about this. I ride an ST-1300 and parts of the Air's got wet when the skies opened up. I stopped and switched boots (and threw on the rain gear of course) and I was perfectly dry in the Canyons for the few hours it rained.

I would get the Clever Air's if air flow and keeping cool in the summer is your primary concern, hands down. They both seem to offer similar protection at the shin, maybe marginally sturdier feeling on the Canyons.

If you're looking for an all around boot that will be a 4 season boot, covering rain freezing temps as well as heat, the Canyons are the way to to imho. I found them warmer in the heat than the Airs but that's not to say I was uncomfortable in them with temps in the 90's. If I didn't have the Air's, I would have been happy to ride in the Canyons all day long. They are a better all around boot.

Hope this helps.

A shopper asked: Which of the two has a stiffer sole? I want to have a boot with decent protection, but will allow me to walk around. Oct 28, 2012

RevZilla: Between the two, the Alpinestars ST Vented Boots is going to be somewhat more flexible when compared to the S-MX5 in not only the sole, but with the entire boot as a whole.

The ST is geared more towards the touring/commuting rider where as the S-MX5 is a dedicated race boot. That being said, the ST will provide more comfort when walking around off the bike.
