SIDI Mythos Gore-Tex Boots 4.6 5 38 38
Great commuting Shoe Use this protective shoe for commuting to work. Provides a decent amount of protection, but as expected not as much as a full height boot will. Gore-tex allows the shoe to breath, but keeps the foot dry as long as your riding pants are long enough to cover the top of the shoe. Decent product great for commuting and casual rides, and as always, Revzilla was fast in getting it here. November 9, 2015
A riding shoe but also an all day sneaker I would definitely recommend these riding shoes! The are very comfortable to wear all day on or off the bike. I wore them a solid 11 hours when we rode to Barber for the vintage festival. I walked around in them all day. Just like wearing a high top sneaker. You do need to wear a good thick sock because the fit is a tad bit wide but manageable. I would buy these again in a heartbeat. Don't shy away from these because of the price. You are getting what you pay for. Ride safe! October 26, 2015
Good riding shoe I tried 4 different riding shoes before settling with the Sidi Mythos Gore Tex. The others would pinch my instep when walking or were too wide or too uncomfortable to walk in after riding. These are not the best at everything but they are pretty good at most everything. I wish they would offer these with some ventilation as they do get pretty warm on a hot day when you stop riding and are walking around in them, nothing you can't live with. The shoes are flexible enough to walk in comfortably and they are the correct width for my foot. They look good under a pair of jeans although I would like a stripe or something to break up all the black on the top of the shoe, but that s just me. I have noticed my feet are a little tired after spending a few hours in them but that is probably because they are not broken in yet. They offer good shifter feel with plenty of protection for the foot and ankle. Overall, I would recommend these and would probably buy them again if something happened to this pair. Sizing is spot on for me. I wear a size 10 or 10 1/2 and a 44 fit me perfectly. I use these when riding a 2006 Buell XB12ss Lightning long. September 7, 2015
Great Shoes These shoes are pretty amazing. I love the look and layout of these shoes. They're also gore-tex so they resist become muggy inside while keeping the water out. This may just be me because I know that I have good feet, but I am able to walk all over my school campus with these on (I put forcefield soles in them), and my feet don't hurt at all. They obviously aren't like walking on a cloud, but it's defiantly doable. They're not built for comfort, but they definitely aren't bad. Style, waterproof (breathable gore-tex), and sturdy protection is where these boots exceed. They get by with a passing C+ grade on comfort. Add an extra sole to the boot and you can bump comfort up to a respectable B. September 5, 2015
good, capable shoes I bought these to replace icon Baja boots because the boots didn't function well on my new bike. (I traded bonnie in to mv agusta# These are expensive but I think it's worth spending more than $200. They fit like regular sneakers and very comfy walking around. Not too heavy and not too stiff. I had to ride in a storm last week and I was drenched but my feet/socks were completely dry when I got home. I was totally amazed about that. #gore-tex us awesome# I live in Vegas and ride in triple digits weather. These don't have much air flow so, my feet tend to get a bit hot. Pros : Water proof, comfort, construction. Cons : Poor air flow, slick soles. #not much traction, especially when the ground is wet) August 19, 2015
Good shoe just a bit too hot for Hawaii. This shoe gives you the peace of mind that your feet/ ankles are well protected. A bit large in size in length and width. Only gripe is that it is too hot for Hawaii weather. No airflow at all. Dogs are really hot after a ride. August 3, 2015
Sidi quality in construction and materials A very nice, although expensive, short boot with protection and waterproof materials. Have worn them for several rides including a 6 hour jaunt over the Cascades. Takes time and effort to get these boots "worked" in so they are not stiff. I wore them a few times for walks around neighborhood and put a lot of effort into massaging the fabric to help the process. They are now beginning to be comfortable. I have 10 year old Sidi half boots that are just about worn out and these are better built. Have not worn in wet weather so there is nothing to report about being water proof. Velcro closure over the shoestrings is a nice touch. I think they are worth the price. July 21, 2015
Fantastic Boot Yea, its a pricey boot but for how I can wear them all day at work and then get caught in a severe rain storm coming home and my feet stay dry says how good this boot is. My first rain experience was in my first full week with them and I had a 10 mile ride home in a monsoon wind and rain and feet were bone dry! I stopped at a red light and my feet stuck to the pavement so good you know these are a well thought out design. Styling is great. I wear Icon Super Duty 4 boots almost every day and they are great but nothing like these. If you want a great boot here is one. I wear a 9.5 for my icons but needed a 43 which per the web site is 9 to 9.5. July 8, 2015

RevZilla Store asked: Why did you choose this?
Terry P: Adequate protection, that doesnt look like industrial boots. Nov 11, 2015
M D: I needed some waterproof kicks for my commutes in the PNW. These fit the bill nicely. My feet have remained dry. Oct 23, 2015
Brien C: I have had good experience with Sidi boots. Sep 3, 2015
Sam D: Again, SIDI is a fine riding boot and waterproof was my main concern; also, just do not feel comfortable in the higher profile boots. Aug 30, 2015
Karen G: I read a lot of short boot reviews. I was looking for ankle, heal and toe protection along with the ability to work around town without feeling weighted to the ground. I also specifically wanted laces for a more secure fit and a means to secure those laces from moving bike parts. This short boot fit my criteria. Jul 18, 2015
M O: Good for walking when off the bike, but they are too short for when it is cold or raining. Jul 17, 2015
Dean S: I thought I liked these but sold to my friend who loves them
I turned around and ordered the TCX street
Jul 1, 2015
Massimo N: Waterproof and nice to wear when you are riding and also plan to walk around a lot (Sturgis...) Jun 29, 2015
Thomas H: I have SIDI boots, looking for a waterproof riding shoe I went with SIDI also. Good quality gear. May 31, 2015
paul c: I have Sidi vertigo boots and they are great...i wanted Sidi quality in a lighter style for all around riding... May 20, 2015
Tyler R: Light weight, good protection, casual combo with jeans. Seemed like a great compromise between protection and style for shorter rides. Ended up returning/exchanging due to need for different foot comfort and different styling preference. May 18, 2015
Stephen J R: Looking for a riding boot that covered the ankles but short enough to walk around in. May 8, 2015
Ernesto E: To use as commuter shoes Apr 19, 2015
Michael M: Wanted a riding shoe that is breathable, waterproof and comfortable for walking in. Apr 16, 2015
Wylie D: Needed a pair of boots for a while and the features of this boots sold me. Wanted something with style yet provided some type of protection from the elements of Maui. Mar 24, 2015
Richard S: Love Sidi boots and wanted a pair that's more comfortable than my offroad boots for street riding Feb 19, 2015
Thomas K: Need some quick-on footwear (sometimes I just can't take the time top put on my boots.) Feb 11, 2015
Jeremy R: Water Proof. Feb 10, 2015
Bronwyn A: My Son is a Motor Bike enthusiast. He asked for these to be purchased for his Christmas present. He researches everything that he buys, so I have no doubt that these boots are exceptional. Dec 10, 2014
Michael C: Commute Dec 3, 2014
Yoo Jin K: Looks like a great choice for casual looking protective water proof boots that are comfortable to walk around in. Nov 28, 2014
Brock H: I have other types of Sidi boots and they are a really good boot company. Plus they seem like the perfect balance of what I am looking for in a riding shoe. Oct 31, 2014
Dennis C: I want the best, wanted a choice of lower ankle boot to use than my full boots. Good reviews. Oct 21, 2014
Ricardo K: The best... Oct 6, 2014
Ken P: Nice styling -- not overly aggressive. Good protection, both from the road and the wet. Oct 1, 2014
Bill B: I wanted something more than a glorified sneaker, these seem to be more technical than the other leading brands offerings.
I love the subtle styling though would have liked the option of something a little more flash also, (maybe next year Sidi?)
I have a pair of Sidi Vertigo boots which are absolutely great on the bike but they are difficult to live in for more than an hour off the bike so I figure the the Mythos should be ideal for legging it around town.
Sep 23, 2014
L S: love the look of these boots and the fact that they're gortex. Aug 31, 2014
JUSTIN C L: sidi Aug 23, 2014

Lucas V: Liked the fact they are Gore-Tex, fit the look i was searching for. Jun 28, 2014
Norbene U: I needed to see the reviews on this items before I purchased the item..so far the reviews at the least 4 stars+, ive own some Alpinestars waterproof/gortex shoes, but I need is these black ones that is required for work at the airport as a porter service handler and so far its been 80% sunny at most times but there has been least a week or more of rain at times in Hawaii May 16, 2014
David B: Research found that these boots are a quality product and an alternative to a larger boot style I typically wear. I haven't had a chance to wear them for any length of time yet, but will review product again as riding season progresses in the Northeast.. Apr 28, 2014
Aaron L: good riding shoe and comfortable when off the bike. Apr 18, 2014

Alfred P: Good looks, good protection Mar 3, 2014

Craig H: After researching other brands, I like this one best for its look, construction and features. Feb 11, 2014

Jim G: Well, they're a new model this year so I don't have much history with them but I do live in the south. I wouldn't say they have a ton of airflow but I have ridden them as high as 88F and I was comfortable. I enjoy these so far and was going to give a full review but haven't gotten around to it. The high top sneaker design should make them comfortable in warm to hot weather. Hope this helps. May 11, 2014

Kenneth B: Absolutely, I live out in the desert and in the heat of the day the tops get a little warm sitting at a stop light but nothing serious. Air flow while riding is excellent. Place a insole in and they fell like my sneakers. These shoes are an excellent purchase as a middle ground before jumping up into a full race boot. May 8, 2014

Brian B: I've only been wearing them in the last month. The outside temperature has been cool, but I wear them indoors when riding to work. Indoors, they do not breath as well as I thought they might for a pure Gortex boot. I'm comparing them to a Revit H20 Fighter boot that did not seem to be as warm indoors. May 8, 2014

David B: I live in the New England area, and I felt with the varied temps from spring thru summer and into fall that these Boots would handle the temps of each season. So far I have found them very comfortable (replaced foot bed) and functional for my riding style.
Quality product for fit and function.

A shopper asked: Will these stretch a little?
Wanting a snug fit and I am between a 9.5 and 10 in a Nike shoe.
Will the 43 in these suffice or am I better ordering a 44?
Apr 27, 2015
Answer this · Send to friends Good question? Yes (0) No (0)
Anton N: Hmm, can't say they stretch much. My recommendation would be to go w the 44. The laces and the Velcro strap will keep your feet snug. That ankle strap keeps you planted!
My fear would be your toes cramping w a 43.

"" ": Hi,
I Love my Boots !
No stretch.
I am the same size as you and 44 fits great.
I got 3 guys I ride with to buy them and they
are very happy with them.
Very water proof !!
Good Luck.

Mike W asked: I currently have a pair of the Alpinestar Fastlane shoes and am looking for a good waterproof alternative. My question is; are you easily able to feel the clutch through these shoes? The reason I wear the Fastlanes atm is purely because of their lightweight comfort and ability to connect with my foot controls through feeling. Jul 12, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
David B: Yes, these Boots do have a good feel to them with the lower foot controls. I have no issue with the function/ feel of them while riding. These Boots are the first of this kind that I have purchased and I'm very pleased with their fit, comfort and function. However, I did replace the foot bed liner with a better quality one. Jul 12, 2014
Reply to David Good answer? Yes (1) No (0)
John K: I can easily feel shifter peg and brake pedal through these shoes. The clutch...? Now that would require some trick riding that's above my level! Seriously, these are the most comfortable motorcycle shoes I've ever owned. Size 10 fit me, same as street shoes, with a finger's amount of room behind my heel when foot pushed all the way forward in shoe, which gives the toes "wiggle room" when the heel is in the back of the shoe where it belongs and it's laced up. These are speed laces, just pull on the tops of the laces and it cinches them up through the loops (not eyelets) and a quick tie. Throw the strap over the tied laces, and you're good to go. Hardly any more time than a slip-on boot. Jul 12, 2014

A shopper asked: The top is made from suede I believe, will this wear on the shifter lever ?. The alpinestars fastbacks were made from an oiled suede top which used to wear badly Dec 20, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Brian B: After one season it looks like the suede is smooth from the shifter, but the the hard nubby part under the suede has no apparent wear. So I guess if a one inch smooth section on the top of an otherwise suede looking boot is a problem, this may not be the boot for you. I hadn't even noticed it until this question. Dec 20, 2014
Reply to Brian Good answer? Yes (0) No (0)
Anton N: The suede doesnt wear. I put about 2000 miles on my boots last summer and so far so good! BTW, they are surprisingly comfortable to walk in too. Some days when I ride to work, I leave them on all day. Not pillows on your feet but comfortable. Dec 20, 2014
Reply to Anton Good answer? Yes (0) No (0)
Collin B: I've been wearing these for about 9 months and don't have any excessive wear. The small rubber dots help grip the shifter and prevent wear. I really like that I can "feel" the shifter through the boot. Dec 20, 2014

Jeff S asked: Hello, does anyone have a comparison between this boot and the tcx x-move? I really liked the fit and comfort of that boot but waterproofing didn't hold up. Rev and tcx were great and gave full warranty even though over a year old. Tried another tcx Jupiter fit was totally different. I wanted the same snug comfortable fit. Don't like my foot squishing around. Wanted vortex too. Thanks Feb 11, 2015

Answer this · Send to friends Good question? Yes (0) No (0)
Brian B: I bet they would be too tight. I have a very narrow foot and got these for those reasons, plus the ties, which can snug them up. FWIW I liked the TCX low cut Gore Tex better because they had a little higher ankle support, but Revzilla said they were a wider boot, so I passed. Feb 12, 2014
