Alpinestars Supertech R V2 Vented Boots

Lacks adjustability, not very strong in a few areas, high price tag. Very strong overall, shape prevents your feet or legs getting snagged onto parts in your motorcycle. Feels quick to break-in. Did I mentioned the side zipper can be difficult to close ? Some feet will fall right at home on these boots, like mine, but others might want to try other brands.

I'm comparing these to my 19-yr old Supertechs (44 EU). Sizing: I've always worn a size 11 Nike Air Pegasus running shoe and my nice dress shoes (Italian) are an 11 and a 10.5. I ordered a 44 EU and it fit perfectly w/re to length and width (I have a normal to slightly narrow foot). I found the inner cushioning to be very form fitting and comfy - my 2005 version always had a little "slop" inside; not so with this version, very little if any heel slip is noticed. My ankles are boney and somewhat prominent - nothing immediately concerns me about the fit around the ankle - there is a lot of noticeable padding; although in certain positions I sometimes feel something that may or may not develop into a hot spot during track wear (first track day with these is 2 days out), but I think with the position on the bike this will not be an issue. Donning and Zipper: I've decided to wear the leathers over the inner booties. I remove the inner bootie from the outer boot and insert my foot, snug the lacing and then zip my leather's pantleg over the inner bootie; I cannot quite get the leather zipper to close completely around the outer bootie - maybe 98-99% zipped. The inner bootie slips into the outer shell very easily (much more readily than my old pair). Pulling the boot's zipper closed the first time was extremely difficult; I kept the boot on for about 20-30 min. and then unzipped and rezipped. The 2nd time zipping the boot was significantly easier - it seems to me that the rubber-like accordion that the zipper is attached to needs to be given time to "relax" a bit. The next day I practiced again putting the boots on with my leathers, paying more attention to where any zipper was having difficulties. The left boot went on OK; the right boot I noticed that the zipper was getting hung up at trying to get over the position of the upper rivet of the inner bootie - by simply pulling a bit outward enabled the zipper to easily get by. Additional comments: I did raise the height of my shifter peg as it seems that the toe box might be a bit higher (and maybe the additional rigidity of the boot didn't allow me to flex the foot like I was accustomed to in my now 19-yr old boots that are being replaced). This is a very slim profile boot - I consider my calves to be normally sized (although I've run for 30+ years, so maybe they are on the larger size of normal). I hope this review helps someone.

Love the look and support the boot provides

I wear size 12 US for most brands. I went with a size 45, and it's a nice snug but not uncomfortable fit appropriate for racing.

I wear 13 US, and the 47 fits nicely in Alpine Stars. The have a pliable, broken-in feel from new.. The ventilation is very noticeable.

I guess I am the exception to the rule. I wear a US 10.5 (regular) in almost every shoe and have purchased four pairs of A* boots in size 45 going back to 2007. They all fit great, not loose at all. I haven't purchased new boots in a few years and so took Van's advice and went with a size 44. They are too tight. I can't imagine them breakinq in enough to be comfortable. Will have to return them and upsize to a 45.

Fits a little over 1 size up. I wear a 44 in smx+ v1 but 45 in the new supertech is spot on. Damn good boot, worth the investment. If street and track day activities are on your list then you will not be disappointed. These boots are amazing. And the men and women at STG make figuring out your size a breeze. 12/10 they’re amazing.

I am an 11.5 and the 46 fit true to size, as comfortable but more protection than my SMX plus

I ordered a European size 48, as I am a U.S. size 14 in most boots. The main issue was the left inner boots was too long for the left outer boot, and it caused the inner boot sole to wrinkle just behind the ball of the foot. The boots overall were too long for my foot and not very wide. Since they had no 47 in stock, I sent them back and ordered a 46. The inner boot on the right foot was perfect and quite comfortable, although a bit long. Hopefully the 46 will work on both feet. The "Hassle Free" return policy was NOT so hassle free. The man on the phone told me I needed to take pictures and measure and email stuff, to which I replied, no, you can take all the pictures you like when I send these 48's back to you. Eventually he agreed to send me a shipping label and they are on their way back, and I payed for a second pair, knowing that Brian will eventually credit me on the first pair.... 5 stars for comfort on the right foot, the left boot issue and lack of QA means 4 stars over all for me.... That could change depending on the quality of the next pair... Boots look fantastic and are simple to get into and out of....
