The Dominator 5 MTB shoe—in a word, it dominates.

The Sidi Dominator 5 is one of our most popular shoes. It assumes that you'll use a mountain bike-specific pedal system such as the Shimano M970, Crankbrothers Egg Beater pedals, or the Speedplay Frog. Since mountain bike cleats are small, they recess flush with the tread on the bottom of your shoes. With recessed cleats you can walk to your heart's content without having to worry about slipping and sliding on your cleats and making a racket as your plastic cleats click-clack on the ground. If you plan on making walking a significant part of your daily riding habits, a mountain bike shoe is ideal -- even if your only bike is a road bike!

The Lorica/Mesh construction of the Sidi Dominator 5 offers superb ventilation and durability. Its Competition sole gives you improved traction and superior mud expulsion to make portaging your bike worlds easier. Sidi knows, too, that bunny hops and creek crossings require a snug fit (without cutting off your circulation). The Ultra SL buckle allows you to micro-adjust strap pressure, so the fit of your upper won't be too loose or too tight. The Ultra SL is mated to a Soft Arch Compression Strap to distribute the pressure of the upper of the shoe over a more dispersed area on the top of your foot. And, High Security Velcro strap (the Dominator 5 has two of these). The Velcro is reinforced with integrated locking teeth to absolutely, positively resist slippage.

The molded plastic heel cup and padded tongue with fit "relievers" are the final small (but important) details that deliver unparalleled comfort in a mountain bike shoe. Available in Black from sizes 38-52.

  • NOTE: Sidi's warranty requires the use of the Crank Brothers Reinforcement Plate (SID0069) when using Crank Brothers pedals.

They work...well.

  • Familiarity: I've put it through the wringer

I have been riding and racing mountain bikes for 18 years and have come to a point where I only use products that hold up to the abuse mountain biking dishes out and that will last a few good years (or more). i.e. Chris King headsets, Thomson, Shimano pedals, DT Swiss hubs and Sidi Dominators. I have tried a few other brands over the years just to make sure I wasn't missing something (Specialized, Giro, Shimano) but came back to the Sidi's after these brands fell apart after one or two seasons. Bottom line, they hold up after severe beatings for several years before needing to be replaced. They are comfortable. The buckle has never failed me. They offer great platform support to transfer energy to the pedals. And for me they fit is perfect for my feet.

  • Familiarity: I've put it through the wringer

I love SIDI hoes. Dominator on the MTB, Genius on the road. 42.5 wide fits me perfectly. Durability is superb.
Insoles suck but that is true of any cycling shoe. I use the G8 Archtech 2600 insoles for a truly custom fit.

Sidi Dominator

  • Familiarity: I've put it through the wringer
  • Fit: True to size

Best shoe so far. Riding and racing Mtb. Bike packing. Adventure riding. Some cx racing. This is my third pair in the last ten years. Fits like a glove. I've had the carbon Dragons also and keep going back for the Dominators.

Sidi Dominator 5

  • Familiarity: I've put it through the wringer
  • Fit: True to size

This was my first pair of Sidi shoes. They are by far the most comfortable mtb shoes that I've ever owned. Whether I'm climbing, descending, or riding on the rock and mud beaches along the Rio Grande, Sidis remain comfortable even when I stop for limited walking or standing still.
It took 2 tries to find the right size but / Competitive Cyclist were great to deal with when making the exchange.
I have a feeling that these shoes will last much longer than my Bontragers did.

buckle broke, buckle broke again

  • Familiarity: I've used it several times
  • Fit: True to size

This is my second pair of Sidi shoes. The previous ones lasted for 15 years. These ones lasted for one rocky mountain bike ride when a thin piece of the buckle broke off. Returned those & the second pair lasted 8 months before the buckle broke again. Great shoes except for the details of the buckle.

Favorite shoes

Been wearing Sidi bicycling shoes since the late eighties. Sidi always provides a good fit for my feet and these are no different.

Tighter Fit.

I have been riding these shoes for many years. The ratchet upper buckle is nice and gives a micro fit. Strap velcro is ok, they have their own velcro style with a rubber center strip with teeth the help with against pull. Additional toe spikes help while hiking, yet I find these shoes pretty slippy and not the most comfortable to hike in since the sole is pretty hard. That translates into a stiff sole that climbs great. So if you have the foot and can get over the price go with these. I have even tried the next model up shoe and find these fit better in my opinion.

Guys/gals': Sounds like a great mtn.bk....

Guys/gals': Sounds like a great mtn.bk. shoe! This would be my first pair of bike shoes (don't believe in skimping on quality); what pedal system do you all recommend? As suggested in the 'ad' above?...(will be mtn./trail riding).
Also, how do they seem to run, fit-wise? Nomally wear a 7 1/2 ladies U.S.
Any help so appriciated

Best Answer Responded on

They run true to size in my opinion. They may have a slightly "european" fit that makes them feel a little narrow - but a tight fit is important with mtn bike shoes. They are also quite adjustable.

I would have to recommend the Crank Brothers Egg Beater pedals. Not because they are super light (they are) or because they shed mud the best (they do), or because of the four-sided entry (great feature) but because they are probably the most popular style right now, and its so so nice to be able to ride a buddy's bike without having to swap pedals.

PS. these shoes last forever... the people that say they've had them for 15 years don't surprise me at all.

Responded on

They fit true to size, I tried a lot of shoes on before choosing the Sidis. I did go with an insole that helped with comfort for hiking my bike and raised my foot for a tighter fit.
Aaron is spot on with the Crank bros pedals. I ride the eggbeaters on my road bike and Candy 2 on my mountain bike for a little extra stability

Responded on

Thanks, guys!

Now, what do you recommend for a great cyclocross bike (currently have a *Trek Fuel EX 8) ?!
...And, the same set up peddle-wise?

Responded on

When I bought my last road bike I had tried a few, The specialized Crux was one I liked a lot. I don't have much for experience with cyclecross bikes. I'm a mountain biker mostly but road bike for training and cardio. I do like to use the same pedals on all my bikes, that way you don't have to swap cleats and can move pedals around without having to worry about your shoes

Responded on

Thanks, that's the exact bike I was thinking of getting!
When I get the $$$$, I'll review how the whole system works out for me; for any other's with the same questions!

Thanks again so very much, very helpful!

Great Shoes!

Side makes the best cycling shoes on the market! I have both Side Road and Mountain Bike shoes and they are great.

Is the shoe you received the same shoe as pictured? On the ladies reveiws, many were saying that the shoe pictured is not what they ended up getting (?); but the most recent review is from 3/12...

Six years of solid service

  • Gender: Male
  • Familiarity: I've put it through the wringer

That's right, six years and lots of trails. The only thing replaced is a buckle. I'm just about due for another pair and I won't hesitate to buy again. Great fit, great value.

Awesome shoe

Fits like my Sidi Genius Wide road shoe, which is exactly what I was looking for. Very comfortable, very durable, stiff sole.

Note: Stiff sole definitely not optimized for walking - can certainly run up a short hill, but it's not as comfortable for walking around as my previous old specialized (but it's much better for riding).

Soles fall apart

I've had 4 pair and three are destroyed because the soles chunk up and fall off. The grey softer rubber just falls off.

Not a good buy at even half price.

Responded on

"Just falls off"? Are you sure you haven't been walking across hot coals?

Responded on

Yeah, second that! Dude you must be walking on razor blades when not peddling. Ive had 2 pair in 15 years. Best money on gear I've ever spent.

Three seasons in

and they're maintaining, but I don't expect them to be my primary shoes for much longer. The insanely long Sidi spikes ripped out of the soles and ruined the threads. Now the toe-box leather, like other people are experiencing, is wearing.

But, after three years of use it's not the end of the world, I'd probably destroyed 3 pairs of $100 kicks by now anyway. Biggest pet pev is the buckle always packs with trail-side vegetation and jams up. You can never get the buckle to release post ride without fussing with it.

I bought these for my road/commuter bike because I need the ability to walk around more than I need carbon fiber supersoles. The shoes feel light and fit very comfortably. They are great for walking around after reaching your destination, and then provide great performance when you're back on your bike. They are definitely worth the price.

Sidi Dominator 5 Narrow!

It's the only shoe that fits my long, flat, and narrow feet (I'm a 46.5 A or B width). The insole/footbed is thin and wimpy, but that's the case with every bike shoe. I can replace it with something better. Sidi Dominators are notoriously sketchy when you need to put your foot down on wet rocks, roots, bridges, my wet deck, etc. The outsoles are hard plastic rather than sticky rubber. The Sidi Dragons ($$$) have softer rubber outsoles which are replaceable for a small fortune. If you've never owned these shoes, they last forever. The synthetic leather uppers and the hard outsoles are tough. The buckles can be fussy when clogged with dirt, debris, dry grass, etc. I've had a tough time loosening the ratcheting mechanism when the buckle is clogged. The heel cup is narrow but flares out away from your heel rather than in toward your achilles. It's a tiny bit loose on me, but my heels are narrow. The more expensive models have a tightening mechanism for the heel cup. Overall a great shoe. Light, durable, and simple.

Good Fit Bad Wear

Very comfy shoe. Rode them 13+ hours and over 55 miles in one day. No waterproofing! Only wear when dry and hot. First day review - bad heel slipage when in hike a bike mode, buckle broke, toe leather showing lots of wear, super comfy, fit one size smaller than you think, fit a wide foot. You can wear these shoes all day as song as you never have to get off your bike, shoes are not great when they hit the dirt, or snow, or water or a walking stride.

These shoes are great though i havent ridden in them yet and i will say that they are true to size don't order larger in fact im thinking i should have ordered a half size smaller but will see when the next pair gets here. good quality well made hope they stand the test of time might look into the optional inner soles as i see they offer a few. plenty wide for regular used to tight fitting these seem looser in the width area but that could be that i ordered a quarter size bigger thinking they would be too small- wrong

sizing issue

Unfortunatly I didn't have the chance to use them, the sizing I figure out with the help of your expert didn't turn out so well and the shoes were way to big, I had to rturn them and now not really feel comfortable ordering again until I'll get he chance to try it on to avoid another mistake.
They look very well made, that all i can say.

Sidi dominator shoe narrow

Shoes fit great as I was told they would and they are in fact narrow I got the 46.5 narrow...Very stiff sole, almost as stiff as carbon. Workmanship looks up to par and they have pretty good grip when walking...My only small gripe is that when I am sprinting really hard and pulling up on pedals as well as pushing down I get a small amount of heal slip. Problem goes away if I cinch down the ratchet but then I start to get pressure points...Will see how shoes holds up long term. I expect for paying 200 plus that they should last several years.
