SIDI Cobra Boots 4.6 5 29 29
good boot for narrow feet i am trying not to give this boot a bad review based off my semi wide feet. my review would be the same if i had picked the right size. nice boot for the money. felt protected while riding. the toe box is cramped both horizontally and vertically. my big toe started going numb and ended my rides sooner than i wanted. i believe it is true to euro feet but not american. i wear a size 9.5 to 10 and got a 43. i have a set of dainese c2b short boots and they are a tad wider and more comfortable in 43. wish i could try a 44 in the cobras but decided to try a different brand. i have more of a wide foot than normal but its kinda right in between.

Graet fit, styling, and protection from this mid-level boot For a boot that's less that $300, and falls into the lower end of Sidi's line of boots, this boot absolutely delivers. It fits great, offers all of the toe, heel, shin and achilles protection that you could want in a road/adventure style boot. I have used this boot on long road touring trips, as well as on offroad trail journeys through the woods on my BMW r1200gs, and this boot has never failed to deliver. While the boot is breathable, I did find that my feet got a lil muggy on particularly hot days, and this not being the rain version of the boot my feet did get just a little wet while riding through a long rainstorm one day. But with the replaceable heel and toe cups, this boot will last you a looong tine. So overall, for the money I feel like this was a fantastic purchase. They got me through totalling my motorcycle when a girl in a sedan swerved in a roundabout and hit me, boots had nothing more than some scratches on the heel and outer toe areas, awesome protection, awesome boots! July 20, 2015
Great protection, great look, and good comfort once you get it broken in. Bought these boots and have been wearing them ever since. With the cold weather we've been having lately, I wanted a pair of boots that will cover up my lower legs and keep the wind off of them. These accomplish this wonderfully. As far as style goes, people ask me about my boots wherever I go. AT LEAST two people a day ask me about my boots. One kid commented that they look like something Ironman would wear, and that they're badass. Fitting wise, toe box is a bit narrow. Had some discomfort with that for a day or so. But overall, the boot is comfortable after it breaks in. Very stiff and "darth vader" like at first, but I walk around in them all day at school and around Walmart etc etc, and there's no problem anymore. I feel like they'd hold up very well in a crash, which is all that truly matters. The first ride I didn't like them much due to the difficulty shifting, but after I rode a few times in it I feel like I can shift better and easier than before. If I had one gripe about these boots, it would be... Nothing. These boots are freaking awesome. April 7, 2015
Good Boots Comfortable while riding but awkward to walk around in. This is my first pair of "Track Boots". They are very comfortable to ride in and have had good range of motion especially considering they are still not broken in yet. Everyday walking around feels very awkward. The sizing fits fairly true to the chart. I wear a men's size 11 US, but the toe feels a bit narrow while standing, but in the riding position the tightness there is far less noticeable. Had there been a EU size 45.5 they would have been a perfect fit. If you have a wider foot and are size 11, I would probably suggest a size 46. I would consider my feet to be on the normal to slightly narrow range Plenty of room in the boots to tuck a race pant into but small enough up top that a pair of straight leg jeans fits over them just fine. March 4, 2015
motorcycle boots they are very comfortable. I love these boots they fit like a regular pair shoes I had a problem because the first pair was small and I had to send them back and they don't hesitate to send me out another pair. The experience with them has been wonderful thank you revzilla. December 22, 2014
Excelentes botas Excelente diseño y calidad son unas botas muy cómodas December 15, 2014
Great touring boot. This is my first true motorcycle boot and after debating between the Fusion and the Cobra I decided to commit to the more expensive but better protected Cobra. Although I didn't end up trying on the Fusion, I think that the Cobra offers better protection for spirited riding while maintaing the comfort of a boot that leans towards the touring/commuting side of the spectrum. I typically wear a nike size 10 and run on the narrow side so I initially bought the 44 but found that far too big, my heel was coming up and was overall very loose. I then returned it for the 43 and am very happy I did so. The boot fits perfect and the toe box gives great feel for shifting. If I start doing more track days I could see myself wanting to step up protection to a Vertigo or even an ST but until then these boots are perfect for what I want to do! I definitely will stay with Sidi. October 20, 2014
Nice Protection, Could be more Comfortable In terms of sizing these boots are right about where you would expect to be. I normally wear anywhere from a 9.5 to 10.5 in most brands of shoes, with my average being a 10. I bought these in 9.5 and they fit fine. In terms of functionality they offer a considerable amount of protection. They're decently comfortable for motorcycle boots, but I wouldn't recommend walking around all day in them. Also, the styling is good for a full-fledged motoboot, but will definitely get you noticed off the bike which can be good or bad depending on your preferences. My only gripe is that they don't have calf adjustment, and that when tucking in riding pants or jeans they can be difficult to zip and that makes them uncomfortable. Great investment for the price though. May 31, 2014

A shopper asked: I cant decide whether to buy the Alpinestar SMX-5 or the SIDI Cobra, looking for comfort when walking and protection- thx Apr 24, 2011

Moto: I've tried both and prefer the S-MX 5 to the Cobra. I have reviews of both on the respective product pages.

In my opinion, the Cobra may have slightly better protection in terms of hard parts. For example, the toe slider and shin protector on the Cobra is larger than those on the S-MX 5 and the Cobra has a lateral slider that's missing from the S-MX 5 (see attached photos, both boots are size 44). The S-MX 5 still, however, feels very protective for this level of boot.

The reason I prefer the S-MX 5 is that, at least for my foot, the S-MX 5 fits MUCH better. The S-MX 5 feels snug yet comfortable, while the Cobra feels very loose around the ankle but almost uncomfortably tight around the toes.

I'd suggest trying both as I think they're both good boots, the S-MX 5 just fit me much better. If both fit me equally as well, I'd probably have gone for the Cobra for what I think is marginally better protection.

BMWM3: SMX-5 is definitely more comfortable than the sidi cobra. They offer the same amount of protection. Sidi's are a little more narrow (hate this personally). Man, for 50 more bux get the dainese TRQ race out boots. They offer crush, twist, extension (forward/backward) so much more protection incase your bike lands on your ankle man. Check out my review I just posted on them. I bought the SMX-5, went to the store, and the guy picked up the boot and goes watch this and bend it in half like a piece of paper. the cobras would do the same. the dainese will not. It's 50 dollars more, and sooo much more protection. I just got the dainese and returned the SMX-5's, it was a great decision. They also look much sportier in person. GREAT BOOT Apr 24, 2011

VICNASTY1989: I was actually considering both of these models myself and ended up going with the SIDI Cobra. The Cobra seemed to be of a much higher quality (build wise) than the A-stars S MX-5, and seemed to be more comfortable as well. It also has replaceable screw on protectors which the S MX-5 does not. The only thing is the Sidi boot seems to be sized a little larger and wider than the A-stars model (so this is something to be considered). -I've tried both and prefer the Sidi Dec 28, 2012

A shopper asked: Okay, looking to purchase my first ever track boot. I have a wide foot. I wear a 10.5 american, so I figure a 45 euro should do well for length. BUT, what brand/model has a wider foot vs. narrow foot? I don't live anywhere near a place that carries the various brands to try on.
I like the look of the Spidi xp wrs, but I think some of the tracks do not allow metal toe slidders. Are they replacable with plastic? I like the look of the Sidi Cobra too
Suggestions are welcome

Stan Z.: Well, you say you have a wide foot, but you really need to be more specific in your question. Are we talking 'EEE' wide here? Notoriously, Italian made boots cater a bit to the narrow side in both heel and toe box. I have a pair of Sidi Fusion Rain boots and they fit narrow. However, I also have a new pair of an older Sidi boot and they fit wide - Sidi Vertigo Air. The later is/was Sidi's track boot. The Fusion is a city/street boot. You can still find Vertigo boots online. I got mine on Ebay. They are D-E width in my opinion. I've tried on Sidi Vortice and they again run narrow. I also own AlpineStar boots and they tend to be snug - again, an Italian boot maker. Sidi, I would tend to say, has revamped the standard way they make boots and to me they tend to be narrow. A-Stars have a better/more normal fit. They're 'boxier' if you will.

You say there is nowhere near you can try on boots in your area? Call your local BMW motorcycle shop. I am pretty sure they'll carry at least Sidi boots there. I'm in the Tampa/St Pete area. The Odessa BMW shop has Sidi boots.

Your best bet is just to order a pair that you like and try them on inside your house for the day. As long as they have not been outside Revzilla will exchange them for another pair or a store credit. Contact Revzilla and a couple other places that ship boots and get mutliple opinions from the sales staff. Most employees ride and give excellent input before you buy.

It's unfortunate, but boots are not a very highly stocked item even in places that carry tons of helmets and jackets.

VinnieT: Any track boot will fit more narrow than say an adventure or touring boot. I wear a EE in regular shoes and have never had a problem fitting into any Sidi race boot (3 pair over the years. Dainese seems to fit tighter in width. Gaerne feels just like Sidi to me. Some of the italian companies will also offer different widths, so you may want to check. Jan 14, 2012

Johnnynyc: I have wide feet as well. Dainese were too narrow for the length of my foot. I opted for Sidi Cobra and they fit much better. Great protection and removable and replaceable toe sliders May 21, 2012

A shopper asked: Ok, thank for the feedback, you have talked me into spending more money, but I think it will be money well spent. I have narrowed it down to these 3 - please let me know what you would buy.
1. Dainese TRQ race out- they dont look like they have that much protection, but look comfy?
2. Sidi Vertigo-
3. Alpinestar - SMX- R

I know if I spend much more, I will get into staight track boots. I want to be able to ride to mall, or wherever and walk aroung for a couple of hours in comfort, but I aslo drive agressive sometimes and value the protection. So are input means a lot to me, so if none of these 300$ boots fits my standart, can you throw me a bone. Thank you for your time. DDD

BMWM3: I looked at all three boots. I tried on all 3 boots. Dainese TRQ race out 100%. Sidi boots are over priced for what you get. You will not regret your purchase! I agree in pictures they do not look so beefy, but look at ALL that shiney plastic, that is HARD plastic that will protect your heel & ankle in case your bike ends up on your ankle. The sidi and the A*'s boots still do not have the features that the dainese does. Its a simple boot thats sporty, yet offers such a great degree of protection. Please go to "Dainese Torque Pro Out Boots Review at RevZilla.com" on youtube and look at the $400 boot review. essentially you get the SAME SAFETY but save $100 because you dont get a gel sole and fancy shiney toe/heal sliders.

Vedel: If these three were my options I would choose the Dainese TRQ race out. This boot is top quality construction and has excellent protection. It looks very comfortable and I have two friends that swear by Dainese equipment so if they came in my size this would be my choice. I like the Sidi Vertigo boot but it is a little bit more track day in appearance and not as flexible as the TRQ. The Alpinestar SMX-R is actually a fantastic boot but I think if I were going to choose an A-star boot I would have to spend the additional 50 bucks for the 2011 SMX-Plus. To be honest any of these are just really, really good so I can't see a bad choice. Nov 14, 2011

Chris K: Just adding my two cents - I agree with the TRQ Race Out by Dainese. I have a pair (the air version) and they are extremely comfortable and definitely convince me that they offer superior protection.

Happy boot shopping!
