Not Exactly "Airy" This is my 3rd pair of Sidi boots. The 1st two pair, which were previous models of this one, lasted about 10 yrs each. The 1st pair succumbed to crash damage, the 2nd pair still going with new soles. Same excellent Sidi quality and fit. The toe box is a bit tighter on these compared to my previous pair of the same size 47. They are less comfortable to walk in due to this – I probably should have went with the next size. To help break these in I sprayed them with Lexol leather conditioner, and it helped. Due to the Achilles protection plate in back these boots are a bit stiffer and took longer to break in compared to the previous pair. I’m a bit disappointed in the “Air” part of these boots. They don’t flow as much as expected. After standing around taking a break, when I start back down the road, if I stick my toes out in the breeze with heels at the ends of the pegs, I can feel some cooling. The cooling goes away with my feet in the normal riding position. This is true on all 3 of my bikes – 1200 Bandit, SV1000, V-Strom 1000. Between the engine pushing hot air around the boots and possibly the boots not flowing much air with toes pointed forward, there isn’t much difference between these and my old solid material boots. When riding in cool weather #50’s#, my feet were fine when in the normal riding position. Stuck out in the breeze they cooled right off. The “Air” boots definitely let the rain right in, though. My old solid material one’s took a while before soaking through, but not these. I like the Fusion boots, but I’m not sure the limited cooling provided by the air version is worth it vs the instant wet socks and feet. June 28, 2015
SIDI Fusion Air - Black - 10US / 44Euro I bought these shoes as an upgrade to my previous basic SIDI Gas riding shoes. They're a huge step up in protection compared to the Gas. These offer all around foot protection including shin protection, in addition to ankle protection, along-with replaceable toe-sliders. I haven't had much riding time in these so they're still breaking in but they aren't very comfortable to walk around in yet (then again, they aren't supposed to be walking boots). They do run a tiny bit smaller so the fit is snugger than I would have liked it to be, especially in the toe area (I don't think you need to up-size). I prefer to have more room, which I believe the competing TCX S-Sportour Boots offer. I have to see how my feet hold up over a long ride. Also, I don't think there's much room in there to add a comfortable "Dr. Scholl's" type insert Overall these are excellent riding boots though I wonder whether they will be practical as commuter boots...

Light and airy Lightweight and easier to walk around in compared to a full fledged racing boot. Fit is a little small so just wear thin socks. March 2, 2015
Good Boots for the Price While shopping for a pair of boots, I went with these because of looks, prices, protection and safety. It's everything I expected. Fitment was no issue, just make sure you go by the video review. I actually these boots for an entire eight hours while working on my feet the entire time, and had no issues. July 21, 2014
Excellent, As Always, From Sidi Just did a 2700 mile tour with these over seven days and had NO foot discomfort. They move a good amount of air, they're lightweight and protection is adequate. They fit true to size for me. July 14, 2014
Sidi quality Very good quality as expected from Sidi. These fit smaller than other Sidi boots I've had. I'd go a size up. They do not vent as well as expected. July 14, 2014
These boots are a tad loose These are slightly loose in the heel and shin area. I tuck my jeans into my boots so its not a big deal for me, but it may be for someone else. Air flow is awesome! The boot is well constructed. June 25, 2014
Great Sidi quality Nice narrow fit that Sidi is known for, flows an incredible amount of air, and looks great. I wish the Fusion Air did not have toe sliders (the Cobra is just above for that) as I'm only using these for street and not track. All other protection is similar to a race boot - shin, ankles inside and out, heel cup, etc. I'm still adjusting to the heel on the sole as my last boots were flat, but I like the way the heel keeps my foot positioned for the brake and shift levers. Overall, an awesome boot that fits my narrowish foot very well. I'll buy Sidi again. June 20, 2014

Matthew H: Thanks for the help, a bit contradictory? Anyway, I've shifted gears and am now considering alpinestars. Those come in an 8. Also see the store is in Philadelphia, just might have to take a road trip....thanks again Apr 16, 2015

Daniel W: They are pretty much on! Maybe a 8 will be like a 8.25 to 8.5 in these. I would buy them in your size. They do take a long time to break in....don't worry! They are great boots for the money! Apr 15, 2015

A shopper asked: How do the SIDI Fusion AIRs compare to the SIDI Clever Airs? Is one lighter than the other? It looks like the Fusion has more race inspired protection elements, but maybe that makes them heavier and they have less air flow? I'm looking for a lighter weight boot that breathes well for shorter rides and destinations to the city. I have another pair of boots I like for longer rides and more exposure to the elements. But I'm looking for something that does better in hotter weather. Sep 21, 2013

Troy S: The fusion air is a very, very light boot compared to what I came from. In fact, it is so light I sometimes worry about the protection factor in a crash. Most of the side is very soft. It is just a thin piece of material covering your foot. I believe that it would easily puncture from an object on the road in the event of a crash. other than that the airflow is great, and the boots are very comfortable.

I can't compare them to the clever air, but these have been great so far.

Scott L: I haven't seen the Clever's in person, but I found the Fushions to be surprisingly cool considering I was riding in DC area heat and humidity. The Fusions have more protection, which is why I was interested in them in the first place. They have saved my foot from getting crushed once already. Sep 25, 2013

Claude V: I love my SIDI Fusion AIRs. I feel the cool air on my socks. These boots saved my leg from amputation when on July 21, 2013 a car did not make a stop and hit me broadside on my left leg. The leather left a print on the bike but I had no broken tibia.

A shopper asked: I typically wear size 8 in Nike running shoes (Nike Free Runs, Nike Lunaracer) and size 6 in Converse Chuck Taylors. Would you guys recommend these boots in size 41 or 42? Sep 6, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Jaime M: I typically wear Nike 9 1/2 sneakers and bought a size 42. They fit a little snug but I prefer this fit to a looser fit since I have more control. I would recommend you try a size 40 or 41 Sep 11, 2013

Eugene R: I usually wear 8.5 in Nikes and I have the boots in size 42 and they fit perfectly. Revzilla has an excellent exchange policy if they don't fit exactly right on the first try. Sep 11, 2013

Routh S asked: After watching the video regarding the product...
I have few questions-
1. What is the difference between Fusion Air and Fusion boots? (key points will do)
2. do Fusion come with toe sliders?
3. Can we attach toe sliders to Fusion Water proof boots?
4. do we get titanium or metal toe sliders for sidi fusion boots?

Thank you.
Shiradi.

Blake K: 1. The Fusion Air boots are perforated leather which makes these boot awesome for warm weather riding.

2. The Fusion Air boots have a removable toe slider.

4. I have looked for an upgraded toe slider for the Fusion boots and to my knowledge they do not make one. You can, however, purchase a standard replacement slider.

DANIEL M: The Fusion Air are perforated to allow some airflow. The Fusion and Fusion Air have hard plastic toe sliders. The Fusion Rain do not have sliders and I don't think they have any mounting points for them. Jul 30, 2014

A shopper asked: My feet are wide at the toe; an "E"
Would this boot accommodate that ?
Jun 14, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
MARK B: I''m not sure of the 'E' wildness range but they're not a wide fitting normally. That said they're better I think compared to Alpinestars and are sizing accurate. If in doubt go a size bigger to help the width i'd suggest... Great quality and value idea for warmer climates. Go for it! Jun 14, 2014
Reply to MARK Good answer? Yes (0) No (0)
Dale L: I always wear a size 9. If I ordered again I would order a 10 in this boot.
They run small. You may want to try these on first somewhere before you buy.

A shopper asked: often wear jeans (or slacks) to the office. Will these go over that, or have to be tucked in. Aug 11, 2012
Answer this · Send to friends Good question? Yes (0) No (0)
Matt S: My ixon jeans fit over but are tighter than with my previous boots (Forma Revenge) due to the more prominate shin protection. I think the slacks may need to be tucked... Unless they're flares... Please tell they're not flares?!? ;•) Aug 13, 2012
Reply to Matt Good answer? Yes (0) No (0)
RevZilla: This will depend on how wide your jeans are. If you are wearing skinny jeans you will have to tuck them in; if you wear baggy jeans, they will go over the boots without any problem. Aug 14, 2012

A shopper asked: What is the difference between these boots and the Fusion Boots other than the perforation? How are these protected in the rain? Apr 30, 2011
Answer this · Send to friends Good question? Yes (0) No (0)
Chris K: There are three Fusion boots currently:

The Fusion Air, the Fusion Rain and the regular Fusion.

The only one that is waterproof is the Fusion Rain, due to the addition of a waterproof liner. The standard fusion does not have any particular advantages one way or the other, and then the Fusion Air is perforated (therefore definitely not waterproof) in order to flow more air in hot weather conditions. Hope this helps!

SupersportRider: These boots are more protection. Much more. They have the Achilles protector and ankle protectors. If I were to low-side and end up with the bike on top of my foot, there's no question I would want to be wearing STs and not Fusions.

As for the rain, these boots are perforated. Do not expect to have dry feet if you wear these in the rain. Buy a pair of Goretex-lined boots for rainy days or you will regret it.
