High quality, nice looking, comfortable, waterproof, ankle protection, covers a lot of bases.
Great riding shoes/boots. Noticeable high-quality feel to the product. I was pleasantly surprised to find that the footbed is a little wider than I expected, it is not the normal narrow euro-foot pattern. I normally wear a 10.5 wide or 11 medium shoe, the size 45 Mythos fit great with enough room for thick socks. Seem to breathe well, no hot dogs on hot days. 30 minute ride in the rain, no leakage. Used for a 1,000 miles so far and there are no markings on toes or anyplace else so it looks like they are going to hold up well. Very pleased with my new Sidi Mythos boots. Money well spent.

Good Riding Shoe
Nothing to compare to but this seems like a great commuter shoe for on/off the bike. Lots of protection without the super technical look. Takes a couple of days to break in but fairly comfortable after that (I normally wear combat boots).

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!

Good choice for lightweight GTX boots
The boots are exactly as advertised: sturdier and more protective than soft riding shoes (sneakers), yet lightweight and unobtrusive compared to full sport riding boots. I was especially interested in the inclusion of Gore-Tex, and that works as you would expect. Of course, the leather--which is of a very good quality--does get wet when riding in a strong downpour, but the interior stays dry so long as you are careful to protect the top edge with your riding pants. I added a DWR coating (Granger's), so now the outside sheds water as well.
The shifter panel offers good tactile feedback, and the soles have a fine level of grip on the pegs.
As others have mentioned, these are actually very comfortable to wear off the bike. I wear mine around the office when casual shoes will suffice. In fact, I hate to take them off and put on boring regular shoes!
Highly recommended.

amazing comfort and great protection
Normally wore a pair of timberlands; i decided it was time to get something more comfortable and with added protection and comfort in mind without looking like a space boots. After 1 week of searching, the reviews on this boot decided my fate. The sizing is right on point (im normally a size 10 in US mens sneakers and a size 10 in these are perfect). I have a wide foot as well as a low arch....PERFECT FIT!!! They dont look like a space boot, they have good protection features, they are comfortable and breathable, steel towed, as well as the sole flex when youre walking feels just the same as a sneaker. i HIGHLY recommend these for anyone. I havent tested the water proof feature, but imagine it holds true as all of the other features have been right on the mark.

I don't leave home without them.
Being from the North West, I needed a comfortable riding boot option that was waterproof, and bonus to if they could pass as a non-riding shoe. These fit the bill.

I wear a US10.5 in most shoes, but I did refer to a pair of barefoot trail shoes to confirm Euro sizing. I ordered a size 44, which is closest to a US10 and they are perfect.

Make sure you're wearing socks high enough to clear the boot, else you're going to have a bad time. They'll rub on your ankle/leg after a while. I wore these on a 6 mile walk this last weekend and they were comfortable the whole way. The footbed is flexible enough for walking around in, but firm enough to not cause any issues when riding. The toe box could stand to be a little wider, but it isn't like your feet will be cramped. Like I said - these are very comfortable. Being waterproof they don't allow for airflow - good on cold days. We'll see how they perform when it gets hot out this summer!

Overall, I highly recommend these boots.

Very comfortable, good protection. Gore-Tex is a bonus!
I wanted a pair of boots more suited to warm weather riding, yet still provide some protection from a summer shower as well as good ankle and toe protection. If the weather is cool or very inclement, I prefer a taller and warmer boot, but for summer I'm willing to trade off some protective features for comfort. I found these boots comfortable both on and off the bike, and the looks and features complement my bike and riding style. I'm a size 10D in dress shoes and athletic shoes, found the length spot on, and the width is roomy. Little to no break-in required.

a good gortex shoe style riding boot
I have only worn this boot for a month but I am happy with it so far. I wear them commuting to work and I don't like the rainy MN weather to dampen my day. I bought them because they look like a nice shoe with some protection and Gortex. They are comfortable and very roomy in the toes, almost too roomy but the size smaller was too tight. If I had to walk around in them all day it would probably bother me but I only wear them riding. I can't speak to the durability. I have had problems in the past with similar lace style systems, using the tabs instead of the holes for the laces, but only time will tell. They are still pretty stiff but I assume they will break in well. They have more protection than a tennis shoe but they are not a race boot.

Again, SIDI is a fine riding boot and waterproof was my main concern; also, just do not feel comfortable in the higher profile boots.
Sam D on Aug 30, 2015
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.
Karen G on Jul 18, 2015
Good for walking when off the bike, but they are too short for when it is cold or raining.

Nice styling -- not overly aggressive. Good protection, both from the road and the wet.
Ken P on Oct 1, 2014
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.

Norbene U on May 16, 2014

Will these work as the Summer riding shoes (20-25 degrees Celsius)? How good is the air flow.

Thanks.
A shopper on May 8, 2014
BEST ANSWER: 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.
where are they made?
A shopper on Feb 5, 2016
BEST ANSWER: My Mythos are labeled as "Made in China". That said, the quality is very good. I have ridden 27,000 miles with these boots in all kinds of weather. They have kept my feet completely dry and they still look good showing almost no wear.
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?
A shopper on Apr 27, 2015
BEST ANSWER: 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.
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.
Mike W on Jul 12, 2014
BEST ANSWER: 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.
Any info on the sizing? Can someone chime in with their size in normal/street shoes like Merrel, compared to these.

Thanks.
A shopper on May 16, 2014
BEST ANSWER: I wear size 9.5 or 10 in street shoes. Sidi size 44 fits me the best. I tried a 43, but it was too small.
i wear a size 7. all I see is 40, 41, 42--- what size would I need?
A shopper on Sep 1, 2016
BEST ANSWER: There is a link to a "size chart" that translates the euro sizes to 'merican next to the size drop down.
Are these shoes CE rated? I'm comparing them to the A Stars SP-1.
Nickolas K on May 13, 2015
BEST ANSWER: I'm note sure if the Sidi Mythos shoes are CE rated, but I highly recommend them. Great fit and reasonably good ankle protection for something less than a boot. Typical Sidi quality.
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
A shopper on Dec 20, 2014
BEST ANSWER: 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.
Two questions. I have a pair of SIDI Doha's. How do these compare to them? Are they sturdier as an example. I get that with the Gore that they are wind and rain repellent. I dont ride much in cold or rain.
Second question is size. My Doha are a 43 and they are a little too wide, I wear a 9.5 in a Nike and a 9 in a dress shoe. Thanks
Ted R on May 2, 2016
BEST ANSWER: Hi Ted
These fit a fairly narrow foot my size is 8.5 US and i find them perfect much like the profile of Nikes and Asic runners. Have not tried a Doha though i have a pair of Sidi Vertigo boots and found them much the same in fit.
I have done about 15,000 kilometers in the Mythos and they have held up exceptionally well, great grip and feel in the soles and the boot material and stitching is sound.
They are warm to ride in due to the Goretex and rain resistant materials.
I would definitely buy these again.
Hope this helps in your decision.
Regards
Bill
Looking for a boot with really good grip ..especially in wet weather..How is the gripping power on these boots?...I have x-miles boot now and they get slippery in the wet
A shopper on Jun 25, 2015
BEST ANSWER: These boots are great, haven't had any slippage in wet weather. Only slippage I recall is from an oil patch in the road once.
