Dominate The Competition

Microfiber Microtech makes all the difference in these unforgettable shoes. Imagined and designed in Italy, the Sidi Men's Dominator 10 Mega MTB Shoe is fit for the name they've been given. These shoes feature a lightweight composition that incorporates resistance, stability, and water repellency — all while being eco-friendly.

The use of Microfibre Microtech allows these shoes to stand leagues apart from the rest. This lightweight material is super resilient for any adventure you decide to ride through. With the Soft Instep closure system, they maintain a lightweight profile and a solid fit on your feet. A reinforced heel device improves the fit by relieving pressure and fitting the shoe securely around your heel, and the Techno-3 system keeps them secure and in place.

Elevate your shoe game with the Dominator 10's. If your trail of choice requires a bit extra grip, the toe spike compatibility provides additional attraction in the muddiest conditions.

Wider than 'normal'
by Anonymous

Bought the Dominator 10 Mega MTB in an effort to reduce the cramped toe box that developed on my Sidi S-Fit MTB shoes over the years. My feet have obviously changed and gotten wider/flatter. Toe box is great, the cabled tightening system is better than the previous velco, on par with the previous ratchet, just hope it's as robust.

Great for wide feet
by Bill in Boston

I use these for MTB, gravel & sometimes road riding. This is my 4th pair from the Sidi Mega series (size 47). I've tried other supposedly wide last shoes, but most are still too narrow in the forefoot for my feet. The Sidi Mega give me the width I need - without being excessively long.

The shoes seem well constructed and are comfortable, with good support and a snug fit in the heel. The replaceable lugs on the toe are a nice upgrade from older models.

The closure system provides a good range of adjustment with an even distribution of tension. Release is very quick also.

great shoe for wide feet
by Criz

I have struggled to find cycling shoes that are comfortable for wide feet and you can ride for extended periods. The Sidi's are by far the best ever. Nicely made, closure works great and keeps the pressure even. Wish I would have found them years ago

Sidi Mega 10 mtn shoes do the job

After 12 years of enjoying Sidi mega road shoes I have switched back to the MTN Sidi mega so I can use the same pedals and shoes for all my bikes.

The Mega Dominator mtn shoes work well, easy to adjust and fine Sidi quality, my go-to shoes

Great shoe for wide feet
by Neal
5 of 5 customers found this review helpful.

My 2009 Dominators were wearing parts of the sole out and it was finally time to replace them. The shoes are still in great shape.

The new Dominator 10 shoes fit my 3E wide feet very well. I'm still getting used to the Boa tightening system. Works fine but the older system was easier to adjust quickly.

I hope these shoes will last as long as my old pair. Perhaps they will outlast this aging body.

Use these on all of my bikes. I always prefer the MTB even though they may be a little heavier. Much easier to walk around in. There was a discount when I purchased these making it all the better.
