These boots flow air better than my A-stars SUPERTECH-R's. Although not as light as the A-Stars you don't notice it when you are on the bike. The fit is secure with good feeling for the controls.

Did a trackday at California speedway and this was my first time wearing the new ST boot. Without question, the most comfortable boot I have ever ridden in. I'm an A-stars guy all the way, but the Sidi boots fit snug and allow for easy manuevering when upshifting and moving around on the pegs.
Between sessions I found them easy to walk around in when unfastened, but once you lock the fasteners for your next round of laps, you can feel that the boot isn't going to go anywhere in the event of a get-off. The 44 fits a US size 10 1/2 like a glove. If you're thinking about it, just pull the trigger and get a pair. You won't regret it.
Yes, I recommend this product.

Alright, I waited quite a bit to write this review because I feel products should be battle tested. I've been wearing these boots for close to 2k miles now and I think they are, without question, the best boot when it comes to airflow and protection.
Firstly, they flow a ridiculous amount of air. The level of airflow would lead one to believe they forgot to put on the boots at all. It's really quite amazing. They flow as much as air as a mesh running shoe, if not more.
They are, without a doubt, an excellent boot when it comes to ankle, foot and heel protection. I have put the toe sliders to use no less than a half dozen times on each boot and they're still in pretty good shape. I'd anticipate having to replace them, depending on how you ride, every 40-50ish times you get a toe down for a prolonged period. I'm not talking about brushing the toe on the pavement, I'm talking about your toe is on the pavement for the better part of the turn. Either way, just tuck that toe in a little bit once you've touched and they'll last you longer.
Comfort wise, these boots are superb. I am a size 10.5 in an Adidas, Asics, etc, and a 43/44 in a dress shoe. I initially ordered the 44 expecting them to fit like all Sidi boots. The 44 was a problem for be because my foot was sliding around, I didn't have a good sense for where the heel, toe and shifter were while under way. Not good. I sent them back for a 43. In the 43, I can feel my toe hitting the front of the boot when I'm walking off the bike. However, once on the bike I have absolutely zero discomfort and no longer notice my toe hitting the front. So much so, in fact, that I honestly can't recall if my toe touches the front or not when my foot is on the pegs.
These boots are not meant to be walked around in. I leave a pair of shoes at my desk in the office or bring a pair with me in my tailbag so that's not such a bad deal. The only thing that really irks me about these boots is that they squeak and squeak a lot. The squeaking noise comes from the joint where the Achilles protector pivots. If you leave the boots unclipped while walking around, the squeaking will cease. I haven't tried lubricating the joint yet, that's my next step. FWIW, the squeaking has gradually gotten worse, not better.
Overall, these boots are amazing. If you require almost-race levels of protection and astounding airflow, look no further. They're pricey, sure, but what's your ankle worth to you? They're comfortable, too, but don't expect to wear them around when off the bike and be perfectly comfortable.
Also, I commute in these boots as well as wear them for track days. They're sexy but also quite wide at the top. If your jeans aren't baggy or aren't a rather wide boot cut, you will end up having to tuck the jean which, in my opinion, looks MUCH better with these boots thanks to the protruding heel.
Yes, I recommend this product.

I wear a 13/48 in the Sidi Sport Rain Boot. Would the Sidi ST run the same size for me, or are they are bit more narrow than the Sidi touring boots?

Answer: 
The ST runs very similar in size to the sport rain and it should be fine to order the 48.

Answer: 
Unfortunately SIDI did not produce enough Black-White to meet the demand. We do not have an ETA yet for these to come in stock again, I would expect to see them availability in May but to most likely sell out very quickly!
