Usually not a lot of love and information around here for Sidi aside from offroad guys. Looks like they have a new boot, the Crossair. Seems to be taking the place of the Atojo. Aside from a short little video with Malcolm I haven't seen any reviews. Anyone tried em out yet?

I've been wondering the same thing but they look just like the Atojo.  Maybe Sidi just decided they didn't like the name and changed it?

If they would offer it with their TA sole i would buy it tomorrow

 I just dont gel with the alpinestar/SRS blunt toe and sole. 

 

Yeah looks like the updated atojo

These are atojos with some parts completely overhauled but most of the boot unchanged. Hard to call it an update, more of a design pivot. Here are some notes about the atojo after 50 hours in them and what changes I see here. 
 

Atojos have been great. As advertised, they’re very light weight but maintain a really good overall stiffness. The external dimensions are also pretty lean and come in a half to full inch shorter than equivalent tech 10s, depending on size. The boots took less than an hour to break in and then stay in that Goldilocks stiffness for much long than other boots. Some boots (tech 7s) go soft really quickly. Some (tech 10s) take a long time to break in, give you some Goldilocks time, then go too soft. As for the stiffness, the Atojos are between tech 7s and tech 10s, but a little closer to the 7s. The stiffness and ankle support is a great balance of hold up and mobility, and the range of motion stops work without being too abrupt. Overall, these are great for motocross. 
 

That doesn’t mean I don’t have complaints, but the new boot looks to have fixed them. First, the material on the gusset was really under spec. It shredded quickly and had a terrible seal. The boot would get dirt in it and, mixed with the stiff sole, would be very noticeable underfoot. The new boot looks like it’s handled the crappy gusset material, but I can’t tell from the pic if it will seal better. 
 

About that stiff sole, the Atojo used the SRS sole with replaceable outsoles. The midsole was stiff feeling on your feet and felt too strong to bend under my 185 lb weight. It also made the boot carry weight really low and feel a little awkward compared to the lightweight shaft materials. The SRS also didn’t make sense with the rest of the boot because it was more thread and panel construction that bolted parts, particularly at the fail points. The SRS sole would outlast irreplaceable parts of the boot, so there wasn’t any point to it. 
 

The new boot looks like it solves this problem. The welded style sole should be lighter and have a little more flex while giving up an unnecessary feature. It also should sit a little lower, I’d think. 
 

Overall, Sidi fixed the chief complaints with this boot and left all the good stuff. If you’re in the market, this is probably going to be a really good set of boots.

Sidi’s are brutal for MX. The sole is far too stiff and offers virtually zero feel through the SRS sole. The TA soled Crossfire 3 is fantastic. 
 

Sidi has custom hollowed SRS soles for Prado and Cairoli. It’s just too rigid for moto. 
 

I actually just saw Keefer talking about this on Twitter as well. I heard the Sidi did very poorly in the shootout due to that sole 

Edit: Looks like the Crossair has a welded sole. This is very enticing. The Atojo had the SRS which was just horrendous for Moto. I look forward to some reviews.

Jam up review man. I really love my crossfire 3 SRSs as I now ride more off-road than moto. And at about 60 hours I’m about due for another pair. But as mentioned above there just isn’t enough feeling. The Crossairs are in the low $400s on the ole chromeburner so I think I’m going to give them a try.

SRS replaceable soles was the reason, why I switch to SIDI. Wink

The new boots are literally identical chassis as the Atojo with a different welded on sole vs the SRS system, the replaceable soles are very convenient and until we see some long term use from the Crossairs its hard to say how long the soles will last.

Sidi quality is really good and the buckle system is wonderful and the atojo is super fast to get on and off with the easy three buckles and the top velcro. Comparing to my Crossfires the Atojos feel a bit stiffer still after 20 hours but much lighter and less hot but also less water resistant from small creek or puddle crossings. 

What I dont like is, im pretty good about riding on the balls of my feet and the new ones look like they have a more plastic material in that area anyways, the SRS I am wearing the very front of the replaceable part which comes up further towards the toe.

Are these guys pretty true to size?

im an 11 in astars and don't know if I should be getting the 11 or 11.5?

I ready the TA are a little wider at the foot which I'm pleased about.

Any insight would be great.

thankyou

Sidis fit true to size. But the TA is extremely wide, never met someone that didn’t think they were too wide. It’s a bit outrageous

Are the TA simply a different sole or are the more off-road oriented?

Was hoping I could wear for both 🤷🏼‍♂️

Crossfire 3 have two different soles. TA and SRS. The boot is the same. They don't fit identical though because the last (the very bottom of the boot) is different. The SIDI size 11 is slightly shorter than an Astars Tech 10 in size 11. The TA fits a little wider so I wear a 10 in those and they are a little tight or an 11 in the SRS and they are just a little loose so I would say sizing is very close but the Sidi boot is stiffer in general except at the ankle where you have a lot more flex than the Tech 10. With a Tech 10 I have trouble dropping my heels because the boot just doesn't want to move even when broken in. The Sidi and Astars fit more similar to each other than they do to Gaerne or Fox.

 

You can wear them for off-road or MX. The TA sole has a little more traction off of the bike due to being able to stick the edge of the sole into soft dirt to get a little more grip when pushing the bike. It isn't really that noticeable. The TA sole might be a little thinner overall, but I have never seen them measured to confirm. The boot is harder than Astars which helps a lot if you hit logs or rocks with your foot.

Just different sole, it’s an MX sole pattern still. 
 

I recommend trying the TA’s on prior to buying. They are extremely wide and if you ride on the balls of your feet they overhang the pegs a lot, makes for a very unusual and not ideal wear pattern.

Any views if Atojo and Crossair are exactly same in sizing?

I currently have size 44 Atojos which are just on the limit being too small.

3/23/2025 9:44am Edited Date/Time 3/23/2025 9:45am

I have a 2 sets of Atojo and tried on crossairs just to see. An yeah their about the same feeling.

That said hate with a passion the atojo, crossair and crossfire srs boots. If they would make them with the TA sole i would by them again. I much prefer the Crossfire TA. There not as wide as being said. I don't notice a general difference in the width of them. What I doo notice is how much more I can feel my bike and pegs with the TA's giving me a much more planted, connected feel to the bike. I also like the welted sole better as there's a small lip on the toe box that fits the shift lever perfectly for quick up shifts. 

If anyone wears a size 43 in sidis I have a set of in really good shape all white Atojo's I'm getting rid of to go back to the crossfire TA open to offers.

I see quite a few guys at the track with Sidi Crossfire TA 3 or whatever they are called.  I have a pair that’s been worn once, soles too hard, tops too stiff.  Well made but not for me. These new Crossair’s are probably a good boot.  They look cool too.

I always liked the crossfire ta. I've a narrow foot, they don't seem wide to me at all. They also have a very low profile top to bottom in toe area, which is great for that shifting thing.

You sure those are crossfire TA and not the crossfire SrS. The SRS sole is way stiffer then the TA to the point that they don't even feel like the same boot when the only difference is the sole.

I bought 2 sets of  Sidi Crossair boots back on December.

I have the black and white ones just like Malcolm wears. 

They are the lightest and best fitting motocross boots I have ever owned

I have several pairs of Tech 10s going for sale on MX Locker this week.

How does sizing compare between the Crossair and the Tech 10's?

image 163Sidi sizing depends on the boot model I think 

The more rigid Crossfire and Crossfire SRS seems to run smaller and are quite narrow.

When I ordered  my Crossair boots I was little concerned that they would run small also- but that was not the case- the Crossair boot is as wide as the Tech 10 and sized the same way as Alpinestars - I ordered 44s in the Crossair and they fit perfectly. 

These are the most comfortable boot I have ever worn. 

Read Keefers review.

I absolutely love my Atojos, the only complaint I could have is the SRS while convinient is quite a stiff sole. I have replaced them once and the uppers are in awesome shape still. These Crossairs would solve my only complaint although id prefer a Atojo TA version. 

The way they buckle up and the big velcro top closure is very well designed and very fast.

I have a set of size 44 Crossair X. The bottom of the boot looks identical to the regular Crossair. They have more room for my toes than a size 10 tech 10 or tech 7. Astars calls those both size 44.5. I find the tech 7 has slightly more room in the toes than the tech 10 in that size. The Sidi is a little tighter in the heel than the Astars. It is similar to the Atojo, but the Crossair has more room for the front 2/3 of your foot. 

Since the Crossair is missing the SRS, the boot seems a little lower. It is easier to get my toe under the shifter than with the Atojo. The Crossair sole has a little more traction on the pegs than the SRS sole but not as much as a tech 10.

If you are debating Crossair vs Crossair X it depends if you want that extra plastic above the ankle. I kind of wish I had saved a little and got the regular model. The regular ones are easier to get buckled and as long as the velcro has the same quality as the Atojo it will last forever.

You still get the typical Sidi crush proof toe box which you don't get with Astars. The ankle support is the same as the Atojo which means it doesn't get soft over time and has a good range of motion out of the box.

Anyone know about how many hours the TA sole will hold up?

 

Got 3 pairs of atojo srs and 2 pairs of crossfire 3 srs and the srs soles wares out pretty quickly.. would be expensive to having to buy new boots at the same rate as they wares out but hopefully the TA soles got more hours in them?

I think they wear a little better than the SRS, but I don't wear out soles so I can't say how it will go for you.

Bought the Crossairs. Testing in a garage I actually cannot feel much peg feel difference to Atojos... In that sense new Atojos might have been maybe better option with changeable SRS. Both outer soles are about rock hard.

Sizing is just the same and I'm missing the half size option. Seems good with thick inner soles thought when I went size bigger from the Atojos.

Top liner is better than in first version of Atojos, but I think they have that update too

Is there a replaceable sole insert on the Crossair? Can’t find any info on it. Unfortunately, I need a boot with soles I can replace quickly at home and I’m wanting to try the Crossair. My Crossfire 3 SRS have been great, but they are starting to show their age after a few seasons. I don’t feel the soles are too stiff, but I’m 200 lbs and wear a 47, so maybe it’s less noticeable.

I have terrible luck with the SRS soles...they wear out quick.  I love the TA soles and they last me the life of the boots.

Supposedly the Crossair sole can be replaced at Sidi or maybe a cobbler. They still make the crossfire 3 though. I think the Atojo is dead.

I recall reading not too long ago someone saying the CF3 would be going away. I’ll most likely grab another pair either way as they are great boots and I need new soles often. Thanks for the info.

The rmatv review of the Crossair X said they were not getting rid of the crossfire.
