Sidi ST Air Boots

Boots looked incredible, workmanship is outstanding , however they did not fit , not even close . I wear a size 13 shoe . These boots were size 48 , I have a pair of Sidi Apex shorty boots that I bought from STG . Also in size 48 , although they are a bit tight in the width , they easily fit . The ST Air’s felt like I was trying to force my foot into a size 10 . And had to return them for a different boot from Alpinestars in a size 50 .

Nice track boots. Fairly easy to get into and out of, lots of plastic armor, and an accurate fit, same as my last Sidi's. Lots of boot for the dollar.

Cant give it a 5 star as these are my first pair into upper end boots. I will say it will be hard to venture to another brand these things are so good. Air flow is awesome when you are riding. Break in doesn't take to long. Sizing is just as reviewed by STG. I wear a 9.5 in new balance and got the 9.5 in sidi. A tad big but nothing a sole insert didnt soak right up plus made them more comfortable. I feel like the size down would have been to small and hurt on longer rides.

Sidi boots fit my feet pretty well, and the ST Air boots are the same. Puting these boots on is easy, the long zip down to the arch of your foot makes getting your foot in easy. Pulling the zip up will give your first insight to the tight calf fit. I found the calf straps that lock the boot a bit tight at first, but they are breaking in fairly well. They have a large range of adjustment and you can adjust each side of your leg independently. I wear my suit with legs inside the boot and once you get it tight and right, they feel very secure. They don't feel as snug as my Dianese Torque boots, but my feet feel secure. The ankle flex is good - just enough for sportbike use, but strong to protect in a crash. I don't like the heal taper. I guess it protects your achilles and heal bone, but now I can't put the kickstand down with my heal, which is annoying. The air flow is good, you will need thick socks in winter, but in summer (or anytime in SoCal!) the airflow is great and will probably help keep nasty smells to a minimum. I recommend them to any sport rider looking for canyon or track day boots. In summary: Easy

Good looks and very comfortable. It takes a little more time to get in them, and the bottom of the shoe is a little vague. But since i have only worn them once,i am sure they will come along! Armor and support is awesome.

I picked these up at the Indy MotoGP last year from STG and absolutely love them. The protection is top notch as is the adjustment for my larger calves. Far more support from the soles and not too bad walking around in either. These are a great upgrade without going overboard on pricing though they still aren't cheap... but good protection comes with a price tag.

Best boots for the money. Great looks. Great protection. Comfortable.

Worn at the track with very minimal break in, the fit and finish was great I just moved up from the Vertigo, very happy
