Incredibly Comfortable and Well Engineered I have a pair of Crossfires for dirt bike riding and they have lasted for 5 yrs now. This is riding trails and racing in Enduro's so they see a lot of miles and terrain that bang the heck out of them. Always feel protected, comfortable, dry and most importantly, NEVER want another pair of boots. This is the same feeling with my new street riding Sidi's Cobras. Easy to put on and take off, well engineered and very comfortable with all the support in all the correct areas. I would NOT want another pair of riding boots. March 16, 2015
Great pair of warm-weather boots for the beginning rider. Lack of lateral ankle protection is an issue. These were my first pair of riding boots and I loved them at first. After getting the SIDI ST Air and TCX S-Speed, I don't think I would buy these again. The biggest issue is the lack of lateral ankle protection (if you can bend the boots sideways, that's bad). If you pay $50 more, the Sidi Vertigo are the best bang for your buck since they work on the street and the track. These Cobra Air are okay for street purposes. What I really like is the air-flow during humid and hot summer (95 degrees plus). Also, they are so easy to take on or off versus the extra 45 seconds for my ST and Mag-1 boots. Also, they are more comfortable to walk in and wear for extended periods because they bend more easily. My other boots are very stiff - yet that protects you more. Decide what you want. I usually wear 9.5D in my dress shoes. I got the 43 and they fit very snug at first. However, after a week they fit fine. You don't want these to be as roomy as pair of comfortable running shoes. That being said, I thought I could get away with the perforated synthetic leather for my region in the winter by wearing thicker socks. First, the thicker socks made these unbearably right. Second, my feet became too cold below 50 degrees at 65 mph. You can buy a 44 to accommodate thicker GORE-Windstopper/GORE-Tex socks, however. SIDI should add reflective visibility panels/piping at the back and front for added safety in low-light conditions. I added some tape, but the gunk from the road sticks to the tape's adhesive so it's messy. If stitched on from the factory, the appearance wouldn't be compromised. January 9, 2015
Nice stylish boots I will have to break in those boots before they become really comfy December 17, 2014
Initial Impressions I just bought these for track days. Good bang for the buck. As always, Revzilla delivered quickly with quality packaging exactly what I ordered. The boots appear well made and fit my wide foot well. My reason for this selection is air flow in addition to protection and I have little doubt of their capacity for either. November 17, 2014
perfect! Great value. Very glad I made this purchase. You will love these. November 4, 2014
Extremely comfortable I have been wearing these boots to ride for about a thousand miles and find them very comfortable for riding. The reinforcement across the boot does not restrict the general movements needed to operate a motorcycle or to walk around. I forgot my casual footwear at work today and was stuck wearing these boots instead. I am often on my feet, and walking ~4 miles today in these boots was perfectly comfortable. I do not have any blisters, and I did not encounter any tasks I couldn't do. They look like something an astronaut might wear, which is awesome, but may not match your formal wear. They are quite expensive, but I feel like they are at least 4 times better than my old $50 pair of boots. November 3, 2014
Great boot, Great price This is my first pair of riding boots, and I wasn't sure what to expect so I read every review that I could find. These boots don't disappoint, I was hoping that Sidi deserved their reputation for excellence... now I'm sure. If you are reading this you might be trying to decide if these are the boots for you, from my experience with them I can confidently say that they deliver on all their promises. If you are trying to decide to order from Revzilla or a different store, Revzilla is more than their promises. Shipping was incredibly fast, my boots arrived sooner than I expected. I will definitely order from them again. September 2, 2014
Nice boot, doesn't fit my feet I have never worn these riding and have returned these due to poor fitment. I wear a size 9.5-10 US and ordered both 44 & 43. -The toe box is very narrow. -The sole feels very weird on my feet, there were multiple pressure points. -The shin protector gap from shin was a little large, mainly to fit in some big leathers. I could still fit my jeans over them. -The ankle protection is kind of lacking and you can bend the ankle side to side a lot. I'm bummed I had to return these but the fit was just not right. I couldn't stand in them for more than 10 minutes. Went with the Alpinestars SMX Plus and they are a dream (for more $$$). September 2, 2014

Brad D: No, these boots are quite perforated and great for hot weather riding, but don't expect your feet to be dry in the rain. Check out the SIDI Cobra Rain boots instead, or SIDI Cobra Gore Tex if you got the coin. Oct 24, 2013

Peter S: Not at all, but am yet to experience boots that are after an hour or so in heavy rain. I slip a pair of sealskinz socks underneath as a water/wind solution. Oct 24, 2013

Philip H: Mine work fine inside my riding-suit pants and inside jeans, as longs as they're not terribly tapered at the bottom. Great boots -- but keep in mind that the fit is quite snug, especially in terms of width, and choose size accordingly. Apr 23, 2014
Reply to Philip Good answer? Yes (0) No (0)
Michael G: I have regular cut jeans. The leg portion of my jeans easily goes over the top of the boot to hide you are wearing them. Apr 23, 2014

RevZilla: The Sidi Cobra Air boot is the perforated version of the Sidi Cobra Boot. It does not have an open/close vent. The Sidi Vertigo Boot has an open/ close vent on the side, while the the Sidi Vortice Boot has it on the toe slider. Jan 17, 2013

Ray C: I would go half a size bigger, they run tight. This is my second pair and for some reason they are tight to the point of hurting my feet. To narrow, I don't have wide feet. So I just packed them with wet news paper for a few weeks, it was a big help. Nov 5, 2014
Reply to Ray Good answer? Yes (0) No (0)
Konrad S: I'm a size 10 to 10.5 and went with the size 10 for these boots. The fit was perfect. On a colder day i was able to put on 2 pairs of socks on and it did NOT get annoying. btw.. ventilation is great in these boots Nov 5, 2014
