Excellent Boot!
I've ridden in Sidi for years, have the Crossfire for offroad/MX and have been through multiple road and race boots.

I got these for summer riding to replace my old Sidi Vortice which have survived multiple crashes at the track but which were finally showing their age and I've relegated them to the back of the bag for the track only to wear them out once and for all while I run these on my other bikes.

The fit out of the box is true to size, and the comfort is, as always with Sidi, amazing! They feel broken-in and ready to go as soon as you put them on.

The Crossfire SRS has the same style quick-adjust snaps at the top, and that makes on/off much quicker and easier than the rotating adjusters on the Vortice--though you do lose the customization the Vortice gives you.

Overall, while it may be cheaper than the Vortice and may be seen as a step down, I think it's greater bang for the buck than the Vortice, and I don't think that the average amateur racer/track junkie or aggressive street rider will miss the Vortice, I know I won't as the ST does everything it should with less hassle.

These boots saved my ankles in a collision. Both vehicles totaled. RIP r6 :(
My first pair of riding boots and going to stick with Sidi. On Feb 8th 2016 I rear ended and totaled my 2014 r6 and a Prius. I can honestly say without the boots to protect my ankles I would have been seriously injured. The impact was at 50-60mph into a nearly stopped car dodging another near accident and my ankles hit hard. The boots held up and came out with some scratches and a loose ankle hinge. I still rock the same boots 2 seasons in a row now. To fix the hinge all I had to do was pop the cover off and tighten the fastener.

Stoked on these boots.

Great Protection and comfort
Break in only takes a few hours and they are very comfortable while riding. Not the best for walking around, but protection is great. So far one track day in them and they feel great. They are built to last.

Got the boot`
Finally pulled the trigger on these. Great quality. Very lite. They feel like they weigh less than my tennis shoes! Nice sturdy sole. Couldn't be easier to get into. I wear a size 8.5 to 9 shoe and bought the 9.5 size. Fit perfectly and are easily wide enough for my EE size foot. Very happy with the purchase. Revzilla service was outstanding as always.

Top quality Italian design and features
Definitely worth the extra cash for these boots. The zipper, Velcro and latching systems work together for a perfectly adjustable fit. I'm not planning on crashing in them, but they're some of the best protection, if needed.

Great all around boot!
I have had the boots now for about two weeks. They are awesome all around. Great for the street and the track. A little stiff when you first get them but once they are broken in, they are hands down the best boot I have owned.

Great track day boot
If you want all the protection you need for normal track days without spending as much as the pros, this is the boot to get. Great style. Easy to take on and off. Not too difficult to walk in. doesn't get too hot.

They did squeak a little after a crash on the track on a rainy day, but that might be my own fault... Can't hear it over the exhaust anyway

Great Fitting Boot
I owned a pair of SIDIs several years ago that were great. Then I had to go and crash test them on a high speed high side. The grinding from the long slide left those SIDIs unusable. However my feet and ankles where left in good shape. The past two seasons I have been using my backup boots from a good company ($400 boots), but just hate them because I have little feel of the pegs.

So, the wife bought me the SIDI STs for my birthday. I have not put any track time on them but they fit great and feel glorious. I am sure I will cut 5-6 seconds off my lap times with these.

Yeah I like SIDI boots, others don't. Find what you like and ride. I recommend SIDIs and Revzilla!
