Dominator 10 Cycling Shoe

Sidi's Dominator line has long been one of the more popular MTB kicks you'll find on the mountain, particularly in disciplines that ask for unwavering stiffness and power, and this year the brand is back to please again with its tenth iteration in the Dominator 10 Cycling Shoe. While the last has remained the same to keep fit true, the Dominator 10 features a host of new technology, including a dual Tecno 3 Boa system for minute adjustments to fit, and all-new Soft Instep 4 closure that reduces pressure to the instep, preventing foot-numbing pressure while you ride.

But thankfully not everything has changed — Sidi stays true to its roots with Microtech Microfibra uppers that are both supple and supportive, without packing in extra weight. These incredibly fine fibers act like a natural leather skin, but have advantages of increased strength, soft texture, and light weight. Being water-repellent, quick-drying, breathable, and permeable to water vapor, it's an ideal material for shoe uppers, and easier to clean than leather. Additionally, this material is resistant to stretching and deterioration from atmospheric agents. And to keep your feet from getting too warm, mesh inserts were added throughout the uppers. To cap it all off, the manufacturing process is environmentally friendly, using only water-based products instead of solvents.

Sidi also continues using its MTB RS17 sole, which they report is lighter and better performing, constructed of a stiff nylon composite that efficiently puts power to the pedals. The tread inserts provide grip on a variety of surfaces and also facilitate mud dispersion. If you need some extra traction in particularly sloppy conditions, the sole is compatible with toe spikes. For those times when you miss a clip-in, the central insert works as a traction pad to help prevent slipping a pedal. Perhaps the most exciting update to the sole is that the toe insert is now replaceable via screws. Considering this area is subjected to more wear, especially when walking, this is a simple and inexpensive way to prolong the life of these already durable shoes.

  • Sidi's coveted MTB kicks get a makeover in their newest iteration
  • Microtech microfiber uppers are light, durable, and water-resistant
  • New Soft Instep 4 closure system reduces foot-numbing pressure
  • Two Tecno 3 dials enable micro-adjustments for dialing a flawless fit
  • Secure your foot in place with help from reinforced heel cup
  • Don't waste your efforts on flex with MTB RS17 nylon composite sole
  • Aggressive lugs improve grip for off-bike efforts

Great shoe to take your bike for a walk

I've put it through the wringer
Runs large
Size Bought
5` 10"
175 lbs

Better walking than distance cycling shoe. Much, much softer than I am used to from Sidi's other top end road and Mt. biking shoes (I love my Shot-Vent road shoes), all of which are pretty stiff to start with, but you really appreciate how well they fit and how well a stiff sole serves you after 75+ miles. These have significantly softer soles, so you feel the cleat/pedal after 20 miles or so. The uppers are also much softer and more compliant. I think if I were mixing a fair amount of runing and walking with my riding, I'd probably appreciate those qualities more.

great shoe for narrower feet

I've used it several times
True to size
Size Bought
225 lbs

Shopped a few sizes of Shimano and could not get the length dialed in correctly. My foot is narrow and the sizing is a little different than expected. The Sidi's fit perfectly. They are a little taller in the toebox than I expected but not as large as the Specialized shoes they replaced. Width is perfect for narrow feet. I have found I need to loosen the lower straps to prevent pain in the ball of my foot and circulation issues. So snug, but not too snug. I am still getting used to the give these have in the toes. Previous shoes had solid carbon fiber lasts. These seem to flex right above the cleat mounts. This makes the shoes great for walking but they might flex under power and might be the source of discomfort on long rides over 40 miles. Still getting used to them in week two and adjusting the cleat position a bit to see if it helps.

Better than Dominator 7 but fit the same

I've used it several times
True to size
Size Bought

Been riding with a pair of Sidi Dominator 7's for the last 1.5 years. They really fit well but I did not care for the velcro and the ratchet strap mechanism for the top closure just would not get tight enough for me and was a pain to work with sometime. Decided to try a pair of Dominator 10's, hoping they fit the same. Absolutely love them and they fit exactly the same! The tension system works extremely well and has plenty of room to get them as tight as I want. No fiddling with velcro that tended to come open or ratchets. You will not be disapointed.
