I Like Big Boots

Great customer service from Brian who took the time to narrow down the options for my hobbit feet. The Sidi Crossair X are the best fitting moto boots I've owned. My typical shoe size is a US 15 2E-4E. The Sidi in a 50 caused me zero pain after a 6 hour break-in ride this past weekend.

Great boots andeven better customer service

I reached out to Brian from atomic and he helped get me into the best boots for my feet! Very comfortable and fit like a glove thanks again Brian

Finally found my boot,Sidi crossair x, thanks Brian

Was struggling finding a boot that fits wide feet. I wear a 12 wide in hokas & euro size 47 in Forma boots for comparison. Brian had me measure my foot & insole length & I was skeptical that he was recommending a Sidi boot & also going down a size to a euro 46. He diagnosed my foot problem correctly, I had been sizing up on boots to gain width when I just needed a wider boot without extra length. The crossair x fits just right, very comfortable, ankle feels very supported, good peg feel, no problems with shifting or braking, feels light on the bike, fast break in time. Very impressed with the boot. The search is finally over.

Great boot

These boots offer excellent ankle and lower leg protection with their double hinge. They fit true to size, and handle normal width and wide feet well. I also like that they "seem" smaller in thattheycan fit your leg well without knee braces or guards. I also consider them generally lightweight, and very comfortable. When on special they are a phenomenal deal for a high protection boot. Not thehighest, but high.

Big upgrade from Crossfire 2 SRS and Crossfire 3 TA

I prefer the precision of the Crossfire 2 SRS but the comfort of the Crossfire 3TA. The Crossair are far better than both-- very precise shifting, better grip on the pegs, better feel on the pegs, and a comfortable toe box like the TA, but not too wide. The three buckles are great and I can go from no knee braces on my ADV bike around town to knee braces for off-roading and dirt biking without having to adjust the buckles. On/off is easy. The lightness is really great, it will be hard to go back. I wear 9.5 in street shoes and 43 fits perfectly with room for a comfort sole upgrade (always thin wool socks for me btw). I thought about getting the HD version but the trial sole just hooks up too much on the pegs making shifting a PIA (I installed trials soles on my TAs). I don't ride hard enduro--in 1st/2nd gear only with my feet on the ground half the time-- and the Crossair soles are plenty grippy for the technical single track, especially compared to rock hard, slippery SRSs. They're vastly better than a trials sole for ADV riding on and off road because shifting is just easier sitting and standing. I try not to dab on big bikes anyway. They also currently cost about half as much as the HD version.

These boots are just great. They are both sturdy and comfortable. I feel extremely well protected whenever i ride wearing them.

Took a bit to break in but once broken in the

Took a bit to break in but once broken in the boots are great! Comfy and good protection!

Brian with Atomic Moto is by far one of the most knowledgeable people when it comes to dirt bike

Brian with Atomic Moto is by far one of the most knowledgeable people when it comes to dirt bike boots and proper fitting. He took the time to help me find the right boots, answered all my questions, and made sure everything fit perfectly. Communication was great, he was genuinely nice to work with, and the entire experience went smoothly. It’s rare to find someone this helpful, trustworthy, and experienced. Highly recommended!
