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
Spot On I live and ride in Alabama, so once Summer gets underway one had best have some well ventilated boots. I have been partial to Sidi over the years, but these Fusion Air boots lead the pack of previous models for several reasons. I have a wide forefoot and narrow heel, so I tend to fluctuate between 10.0E to 11.5D shoe sizes depending on the design. These Fusion Air boots in a 46 (11.5) fit my hooves NICELY. Some previous Sidi models have had a narrow toe box that reeks havoc with my wide forefoot, but Sidi has returned to a wider, more rounded box with the Fusion line. Ventilation is plain OUTSTANDING! In fact if the temperature is not out of the 50's or low 60's, you might leave these at home and wear your non vented pair....very airy. Design is OUSTANDING as well...protection, function, and looks...it's all there. Shoes/boots tend to be a very "personal" thing due to fit, but these are pretty much spot on in siding for my previously described feet...I highly recommend them. March 31, 2014
Best for warm climates. The Sidi Fusion Air boots have exceeded my expectations. I ride in Florida, and I've always battled with hot, sweaty feet when wearing boots. The Fusion Air boots have fixed that. When you're riding you can really feel the air moving through, keeping your feet comfy. They're very nice to walk in as well. Two precautions: I had to return the first set and order the next larger size. (Revzilla made that fast and easy.) These are not waterproof. Order a set of rain covers for them if you're going to ride in the wet. March 13, 2014
Good commuter/touring boot. I haven't had a chance to ride in these yet because there is snow in my yard but I have worn these around my house. These boots are pretty comfy, no complaints. I was interested in the alpinestars smx-5's origionally but when I tried them on at a local shop I seemed to be in between sizes. The astars look cool but flopped around too much. So I took a chance and ordered these without ever seeing them in person and they fit perfect. I wear size 11 DC shoes with a normal width foot and the 10.5 astars were too wide and loose. I got a size 11 in the fusions and they're perfect. Nice and comfy with a slender profile. ( RIDE 1998 Suzuki TL1000R) December 30, 2013

RevZilla Store asked: Why did you choose this?
John P: Nice tall, stiff street boot Jun 27, 2014
Chuck F: Great boots, light and comfortable. Passes plenty of air keeping my feet cool in hot weather while still offering good protection. May 13, 2014
Timothy T: I also have a pair of Sidi Adventure Gortex boots that are too hot in the summer. I always wear Sidi because of the quality and fit. I have a narrow foot and Sidi fits me great. Apr 6, 2014
Charles B: Good Protection and nice looking while not being too hardcore as im only a learner Apr 4, 2014
James M: I hope these will breathe well and keep my feet cool and dry. Apr 4, 2014
Steve O: SIDI has always had a good reputation for making quality boots, and I thought that these look like what I need for my aggressive-commute to work on my sportbike. Dec 12, 2013
L A: I've generally wore Timberland boots not realizing how unsafe it has been not to have riding boots. Great bang for the buck. Aug 16, 2013
Claude V: These boots are the best quality. They saved my ankle and chin bone from a direct hit by a car on June 21, 2013. Thanks to the quality of these boots, I have no broken bones. Aug 14, 2013
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
Reply to Jaime Good answer? Yes (0) No (0)
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

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.
