SIDI Fusion Air Boots 4.7 5 24 24
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
Very Solid On the Size: Almost everyone owns a pair of Chuck Taylor sneakers, so I will base my comparison on that. I wear a US11/EUR45 and they fit me like a dream (I also have a second toe which is significantly longer than my big one, which may be worth noting as it has affected the fit of different sizes in different brands throughout the years). I ordered the SIDI boots in US11.5/EUR46 and they fit very well. On the Fit: It is obvious that these boots were designed to fit on a foot that is flexed into a riding position, which makes perfect sense. Standing flat-footed, and straight-legged, the boots press the foot forward slightly above the achilles tendon which has the effect of pushing your toes further into the tip of the boot. This gives the false impression of being smaller than they actually are. If when standing normally you bend your knees slightly or lift your toes while keeping your heels on the ground you will notice that your heel slides back into the hard, molded heel cup and you no longer have your toes squeezed into the tip of the boot. Also, I did not find these boots to be as freakishly narrow as some of the other reviewers let on. Again, I feel this apparent narrowness or discomfort is eliminated simply by having your feet on the pegs rather than bearing the full weight of your body. The build quality is outstanding and anatomically speaking the boot covers all of the hard and soft bits with pads and armor in a reassuring way. As far as walking around comfort...I didn't buy these to walk around in. Vented or not, they probably would be too hot for the Texas heat. I keep pair of thin slip-ons in my kit for when I need to walk. On that score, these are large boots. If you're going to take them off while out and about this presents a problem of storage...add the bulk of these to your over-pants, jacket, helmet, etc....and maybe it's best to just stay on the bike? Probably. October 14, 2013
Very Stylish I ordered this boot about a week ago and got it a couple of days ago. They look absolutely great and offer quite a bit of protection for the price. The problem for me is that they are not comfortable at all for me. I don't plan to wear them all day like I would a regular shoe, but if I'm out somewhere all day, at some point, I will be doing some walking around. However, just walking around on the carpet in my house, they hurt like heck and the other thing is my jeans barely fit over the boot and I don't wear wide legged jeans. These would probably fit someone with narrower feet, but I'm going to have to send them back. I was hoping to get the ICON Water Patrol boots b/c I hear they are comfortable enough to wear all day, but I've seen reviews where people have issues with the buckles and laces coming apart and having a hard time getting warranty service from ICON. So we'll see what's next. And I was so excited to get these too. September 6, 2013
Excellent boots As my first pair and as a beginner rider, these boots are exemplary. I was searching for a good pair of riding boots with safety and comfort as my main considerations. After I searched many websites and many boots, I came across these and I simply could not find better in their price range. They are safe, stylish, great for airflow, true to size, slightly narrow, durable, wide mouthed to tuck in pants, rather inconspicuous under pant legs, long-walk-able, and about as comfortable as dress shoes. A pair of insoles made them perfectly comfortable to wear around and throughout the day, however. There really is nothing negative about these boots! September 3, 2013
Love these boots These are technically track boots, but I've been using them for street riding and they're awesome. Good traction, good feel for the controls, and great styling. I don't know yet how they hold up for track use, but they work great for the street. Highly recommended. August 14, 2013
Great Summer riding boot. This is my second pair of Sidi motorcycle boots. I also have the Sidi Fusion Rain model which is an excellent boot for cooler and wetter conditions. I bought these for the hot summers in Eastern Washington. I was skeptical due to the lack of visible air vents in the boot. However, the air flow is surprising. I recently wore these on an 80 mile ride in temperatures just over 100 degrees . My feet stayed cool and dry. I will also wear them daily during my commute to work where I will rarely reach speeds above 35mph. Even at this speed, I will still notice airflow. The one downside would be that there tends to be a lack of airflow around the shin guards. Very happy with these boots for warm weather riding. They can be somewhat uncomfortable when walking around for distances, but I bought them primarily for riding, not walking. July 28, 2013

RevZilla Store asked: Why did you choose this?
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

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: 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?!? ;?Ģ) Aug 13, 2012

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.
