Dominate comfortably.

Sidi's Dominator shoes have long been a favorite for their ability to handle just about any mix of grass, rock, mud, sand, and even tarmac, and the Dominator Fit Mega Shoes expand the model's appeal both figuratively and literally. Sized specifically for riders who wear wide shoes, the Dominator Mega has all of the features of its slimmer sibling with a more forgiving fit to accommodate higher insteps and wider metatarsals. Providing multiple fit options is not something we see offered very frequently in shoes of this level, but it's no surprise that the fit aficionados at Sidi saw a need to accommodate more cyclists with their shoes.

Sidi shapes the shoes' uppers with its relatively new microfiber microtech, a material that creates fewer toxic emissions during its construction for a smaller environmental impact than other synthetic materials. Despite the change in production method, it retains the combination of water-repellency, low weight, and durability that you'd expect from a Sidi shoe.

The perforations along the top of the shoe encourage airflow and breathability throughout the uppers, and the combination of two hook-and-loop straps and Sidi's classic ratcheting buckle give you the ability to make micro-adjustments across the sensitive areas along the top of your foot. Sidi's penchant for addressing fit minutiae shows through with the Soft Instep top strap, which adds cushioning and distributes pressure more evenly across the top of the instep.

As you pedal on-trail or off with the Dominators, the reinforced heel cup and the composite nylon MTB Competition Sole work together to encourage consistent power transfer from your legs to the pedals, carrying you through any mix of sand pits, smooth singletrack, or rock gardens without giving out. For the days when the terrain demands additional traction, the shoes have space for two toe spikes to give you some extra stability.

  • Wide cycling shoes alleviate cramping for bigger feet
  • Competition nylon sole efficiently transfers power
  • Aggressive tread pattern for sure-footed traction
  • Supple microfiber upper is abrasion and water-resistant
  • Caliper buckle system offers micro-adjustable fit
  • Sidi fuses Italian craftsmanship with functional design

My Third Pair of an Icon

    This is my third pair of the Dominator and first with the Mega cut. Material advancements making them lighter and cooler without sacrificing performance. The Mega size is definitely a welcomed option for me, as I have slightly wider feet. Looking forward to another 10 years with these!

    Can you tell me the difference in dimensions of the Sidi Denominator regular width versus the mega (wide) width? Size 40 or 41.
    Thank you.

    Sidi web site says they are 4mm wider.

    Could be better...

    • Fit: True to size
    • Size Bought: 8.5

    Width was fine, but the height/ volume was narrow. Also, the leather is cut with no finish so the tongue really rubs. Ended up with the Shimano Wide' option for me, was cheaper (and price wasn't a concern) and more comfortable due to edges being 'finished' so it wouldn't rub (better then Spesh too!).

    Very stiff tongue

    • Familiarity: I returned this product before using it
    • Fit: True to size
    • Size Bought: 47

    I will start by saying I have always had a hard time with shoes. I wear a 12 1/2 which is hard to find but in cycling shoes this would typically equate to a 47. I also have a flattish foot. Sometimes I can wear a 12 wide depending on the shoe but I don't have a wide foot. I went with these using the guide and the length was spot on. I didn't need the mega. I decided to not go with the Sidi because the tongue was so crazy stiff that I thought it would probably cause significant issues. I gave it three stars because the quality seemed great and the buckles are nice. My personal issue with sizing is my deal.

    I found the same issue with the tongue. It's just a piece of leather CUT instead of finished. Try the Shimano Wide's! Old style Spesh were great, but no longer for my duck feet! Shimano are a great fit!

    What shoes would you recommend if I wanted a more all mountain but i do really like my old leather Sidi Dominator 5 that I've had for over 10 years and grown to ignore the downsides to the hard cleats
    I'd like to have more confidence when walking in the rocks but still want a performance shoe that fits as well as my Sidi's

    This is review for WIDE, so assuming that's your need, if so, try Shimano. I found good width, nice finish.

    Exactly what you'd expect.

    • Familiarity: I've put it through the wringer

    The Italians have some magic that the rest of the world just hasn't figured out yet. Three word review: Attractive, durable, fast. I've loved my Dominators, and honestly, I'll probably use them until I can afford a pair of their higher-end relitives.

    Stiff shoe for wide feet with downsides

    • Familiarity: I've put it through the wringer

    These shoes are super stiff and accommodate wider feet. I have a neuroma that now limits a lot of my activities. These shoes help alleviate that neuroma pain. Lots of times the two front velcro straps are hardly tightened down.
    These shoes have taken a beating from bashing rocks and only have a slight stitching tear. They are VERY durable, which ads value in my book.
    Downsides that I tolerate because they perform great and relieve the neuroma:
    I wish the shoe was as comfortable for me as others enjoy!
    See the product picture--The depression at the end of the leather tongue in the toebox pushes down on my foot and rubs the top of my foot. I have tried to reverse the depression with a boot press, but it always goes back to its original form and rubs my foot (raw at times).
    Even when new, the ratchet buckle tends to loosen as I ride and constantly have to ratchet it back to tight. Most all my MTB shoes have this issue anyway, so whatever....
    The plastic cleats are pretty slippery, so when things get damp, watch your step!
    Wish Sidi could resolve that issue by putting a rubber compound on the ends of the cleats that has some grip when walking logs and rocks.
    Overall- great performance shoe that is really not that comfy for me. But I tolerate it because it works for the neuroma.
    It is cool in the summer, but when it gets colder in fall, my feet get numb.
    I would like to find another MTB/Cross bike shoe that is as stiff and wide, but more comfortable/warmer. Any suggestions??

    I was wondering about that toe box concern. I have some now that I’m trying on for size and thinking this might be a deal breaker.

    Great shoes and even better customer ser

    • Familiarity: I've put it through the wringer
    • Fit: Runs small
    • Size Bought: 42.5 and 43

    I ordered the 42.5 size and it proved to be too tight in the front, the cyclist representative was super helpful and sent me a pair of 43's that fit great!

    Also, when they received my returned pair I got a prompt refund.

    This is now my first goto site for all of the categories that they cover

    Still the best

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 43.5

    After riding the bottoms off my old SIDI Dominators a few years ago, I decided to "save some money" and try a few other brands of shoes. None came close to the Dominator. If you want a shoe to last season after season, spend the money. You won't regret it. There is a reason these have been around for so long, they are simply the best shoe you can mate to your pedals.

    Materials feel great wide in toe box

    • Fit: Runs small

    Materials and intial quality feel great. They have been very durable so far. Shoes have plenty of room in the toe box wish they were a little wider in the middle of the foot.

    Are the cleats of the dominator softer like the dragons or spider model?

    The cleats on these shoes a very hard, Sidi built them to last, not for traction. I don't use them on rocky or wet trails.

    The best "Wide" cycling shoe available.

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 40.0

    This is my second pair of the Sidi Mega Dominator. I replaced my old pair of 11 years and many times I glued the tread back down. You can not replace the tread (unlike the Drako version). Buckles and strap can be replaced. There is no break-in process. These are the only shoes I've found that can accommodate my wide(size EE) small foot and they are super comfy on and off the bike..

    Sidi Dominator Mega

    • Fit: Runs large
    • Size Bought: 41.5

    Real nice quality. Wide is defintely wide! Unfortuantely, toe box HEIGHT wasn't roomy enough. Had to return. If width is critical, this shoe will do, but I also need a slightly higher volume in front of shoe. Found a competitors brand, but that wasn't wide enough. Go figure.
    Sidi's 41.5 is about an 8.75 US in my opinion

    Hands down the best

    • Familiarity: I've used it several times

    Best shoes for cycling ever. They last forever and a day. They have replaceable buckles and parts if they ever do wear out. Simply the best shoe going. I put a ton of miles on them every year. They feel great out of the box and only get better with age.
