SIDI Apex Boots 4.8 5 43 43
Great boots! I chose these Sidi Apex boots because I was looking for boots that would provide good protection for street riding, would feel comfortable and look good. I'm completely satisfied with them! They are exceptionally comfortable while I'm riding, and also very comfortable when walking short distances. And they look great -- stylish, but not overstated. Also, they look like they would provide good protection if needed. The fit seems slightly on the small side. However, when I tried going up one size the boot was way too big, so I ended up sticking with the size that I usually wear. One minor criticism is that the insole is glued in. I needed to remove the insoles so that I could put my custom orthotics in the boots. This was difficult to do because Sidi used very strong glue. Fortunately only in a few places (i.e., not applied to the entire underside of the insole), so I was eventually able to remove them to make room for my orthotics. But this will not affect most people and in any case I'm not going to deduct a star for such a minor inconvenience when I'm so impressed with the boots overall. January 19, 2015
Good commuter motorcycyle boots! These boots fit perfectly on me. You're sacrificing shin protection for something that is a bit more comfortable then a full blown motorcycle boot, but the rest of the protective features are there. The only thing I can really complain about is the opening of the boot; it's a bit too wide. I figure that the intent is for scrunching up the lower part of your pants and placing them inside the boot. This would be to avoid your pants getting stuck on something. It's nothing major to complain about but I would have liked them to have some kind of strap to close the opening a bit in the event I am not using it. December 30, 2014
Excellent Boot For Street Riding I got this boot because I wanted excellent protection and to be able to easily wear the boots under my jeans. I looked at the Fusion Boot but it did not fit under my jeans. Overall this is a great boot because it combines protection with functionality. Perfect for quick trips to the gym or all day rides. November 16, 2014
Excellent short boots I was looking for a pair of boots to commute to work, with out using a full boot or a riding sneaker, and this boots are the perfect answer to my requirement. And you can't go wrong with SIDI, this are a nice looking boots. October 14, 2014
Great commuter boot I wear these to work everyday and I don't really have any complaints. I like how I can wear them out to dinner with friends without looking too flashy and also how easy they are to put on and take off. The toe area is a little tight for my wider feet but either they broke in a little or I got used to it. All in all, I can see myself getting another pair if anything were to happen to these. October 13, 2014
Great style & protection Great boots that recall the look of full racing boots, and offer similar appearance and features (though with a lower cuff and price point). They appear to be quite durable, and the adjustable venting is functional. Foot area seems true to size, and stiff footbed is great on the pegs (but would be murder to walk much distance). Cuff seems pretty large to me, but I'm not sure you'd tuck pant legs inside them (mostly because they are so much shorter than full race boots). September 29, 2014
Great boots! very pleased, would purchase again, fit true to size, comfortable to wear when not on the bike as well September 1, 2014
Great Product - Great Brand I have logged just over 400 miles on these boots. The fit and finish work is typical Sidi quality and is matched second to none especially at this price point. I have used Sidi cycling shoes for over 20 years and have come to appreciate their long term durability and overall quality. The ability to replace small parts from wear and tear is a great feature and the Lorica will no doubt hold up well overtime. Sizing was one size down from what I normally wear in the cycling shoes but Revzilla's return process is quick and painless. The boots have great airflow and make for a awesome commuter and weekend riding boot. The only draw back is the lack of insole and carries over to all of their shoes. This is a somewhat non issue as quality insoles can be had for next to nothing. I have a small volume foot so this will help take up just a bit of wiggle room in the boots once done. August 26, 2014

Tim H: Quality of SIDI, price, low cut style Aug 21, 2014
Nicholaus H: The reviews were good and this shoe will fit as a good daily commuter and weekend riding boot I feel from the description. I have been using Sidi cycling shoes exclusively and expect their Moto boots to be of equal quality. If these work well I may plan on buying a fuller coverage boot like the Sidi Canyon. Aug 13, 2014
Christopher A: I am a new rider, getting my first set of gear together. A guy at work has pointed me in the right direction on choosing the proper gear for comfort and protection. I look forward to getting these boots added to my collection of gear! Cant wait to get on the road as a rider with the rest of the biker community! Aug 7, 2014
Ryan W: Good reviews, didn't want to sacrifice function for looks Aug 4, 2014
Mike M: Looking for a lower boot that offers good protection, without going into a full racing boot. Jul 28, 2014
Ken A: to see if the higher boot is more secure feeling than the Dianese CB 2 shoe. Not sure about the zipper fit or the fact that a 47 is a 12.5 instead of 13. We will see Jul 8, 2014
Dave S: "These boots were made for walking"...and ridin'. Nancy Sinatra had it going on, back in the day. Google it. You'll see. Jun 19, 2014

Very good quality and design.

Donald S: Looks cool Jun 8, 2014
Elbridge J: Needed boots lol Jun 4, 2014
Ryan D: After looking at 50+ boots I was torn between these and the Spidi XP3. I decided on these because I'm new to riding, was not totally sold on full on racing boot, and these seemed to have the most potential comfort off the bike while offering great protection. May 20, 2014
Paul B: I wanted the best protection in a low summer riding boot. May 8, 2014

Michael T: They are cut pretty true... I mostly wear a size 12 but occassionally I need a 13 and I ordered the 12.5/47 and the fit was spot on. The 11.5/46 should be perfect for you. Apr 22, 2013

steven b asked: hi im coming from the speed and strenght momment of truth shoes and mines have adjustability across the top for when the leather/shoe stretches so the shoe never becomes loose. it seems like theese boot do not have any adustability do you feel that theese boots will stretch too much with everyday use due to lack of adjustability to keep them snug ?

Andy K: Steven, not worn these a tremendous amount, but I would say in common with most European brands the width tends towards narrow. Also these are made of a synthetic material rather than leather so in theory they shouldn't stretch as much. Sorry to be a bit vague but Sidi is a quality brand and these are great boots so I don't think you'll be dissapointed. Nov 4, 2014

Miguel D: Hi Steven, these are my first pair of riding shoes and I have to say that I'm very
Happy with them. I always have to break shoes in before I'm comfortable in them, not the case with these shoes. Mine are holding up well I'm not noticing any problems with the shoes stretching. I highly recommend them, hope this helps you .

Rocky T: These boots are very sturdy and don't have room for adjustability. The 1st few times walking in them they felt like I was walking on stilts, but that went away after breaking them in. I always get compliments with these on as well. Definitely a buy you won't regret! Nov 5, 2014

James M: I wear zip up leather pants tucked inside. They are pretty short boots so pants tend to creep out of the top when riding. I believe I would rather wear jeans on the outside. These are great boots! Very comfortable and well made. Oct 22, 2013
Reply to James Good answer? Yes (0) No (0)
Eddie J C: Not really, they are ment to go under your pants. I would get the sidi st or st air if you want to wear your boots over your jeans. The apex is more of a riding shoe than a boot. Oct 20, 2013

Ted B: I don't think the jeans would stay in. I always wear the jeans outside the boot. OBTW the boots are comfortable and function is great.

A shopper asked: Hey! Love your reviews. Question: Sidi Apex or Streetburner?? I'm a noobie, will be commuting to work, walking around, and I obviously want protection. Pros/cons of each?

Josh C: I started off with the Sidi Apex and I wasn't satisfied with their ankle support. They will protect your ankle from abrasion and light impact but not twisting or bending. If ankle support isn't a priority I would recommend the Apex boots, they are comfortable. They don't breathe very well off the bike so if you have sweaty feet that might be an issue.

If you do want more ankle support, full size boots are just as comfortable and you can conceal them under jeans with relative ease. I wear my sidi st boots under jeans all the time without issue.

greg b: These boots are great. Comfort and fit were very important in the selection of these boots. I can say that I would purchase another pair and enjoy them when on my sport and touring bikes. The sizing matched my regular shoe size and Revzilla is a great place to make purchases. Sep 26, 2013

Answer this · Send to friends Good question? Yes (0) No (0)
Michael S: No. They are water resistant, so your feet will stay fairly dry if you ride in the rain, but if you submerge your foot in water this boot will leak. Sep 17, 2013

ROBERTO S: Yes they are Sep 17, 2013

David S: I live in Southern California so not too many wet days. However, I have ridden in a downpour with these along with several "damp" foggy days a week on my daily commute. I have never had a problem with wet feet. There is a vent on the outside of each boot that I make sure is closed before heading out on those foggy mornings. Depending on the weather where you are at, these might be the right boot for you. On an unrelated note, best boots I have owned for daily riding. Snug, comfy, and a level of protection not found with others in its class. Sep 17, 2013
Reply to David Good answer? Yes (0) No (0)
Michael T: They are not waterproof per se, but I have found them to be good when I get caught in the rain. If you ride in the rain for long enough then water will get in through the side vents and there is no gaiter behind the zipper (although the zipper is on the inside of the foot so is less exposed to the rain).

So in short, I would not wear these boots on any trip where I was expecting significant rain but if you get caught they hold up quite well.

Robert B: I have rode in light rain without problems. But I think it you were planning on riding in the rain they would not keep your feet dry. They are well vented so you I will get water in the vents. The zipper does not seem to be water tight either. I will say they are great boots. I have worn them about 8k miles. Many time for 5 to 6 hours and I love them. Sep 18, 2013
