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.
