Timeless.

Cycling is one of the most frantically innovative industries in the world, so when a design maintains its effectiveness well enough to be labeled "timeless," then it's clearly got something going for it. The predecessors of the Sidi Men's Genius Fit Carbon Mega Shoes earned that title years ago, and the latest iteration ensures that the Genius Fit Mega's place in the wide-footed cyclist's wardrobe is safe for another year.

Like its more slender counterpart, the Genius Fit Mega features Sidi's beloved ratcheting buckle for retention. You're no doubt familiar with its micro-adjustment operation, which lets you vary strap pressure to nail the perfect fit, every time. The Soft Arch Compression Strap evenly spreads the upward stroke pedaling forces across the top of your foot while also alleviating the discomfort of over-tightening. The mid- and forefoot fit is managed by a pair of standard Sidi hook-and-loop straps that feature an additional strip of polymer teeth to ensure secure locking.

The uppers' mesh-ventilated Technomicro material is water-repellent, quick-drying, and breathable as well as abrasion- and mildew-resistant for comfort that lasts throughout your ride. It also resists stretching, so the precise fit of the fastening buckle won't be compromised during long days and hard efforts.

The Millennium 4 Carbon Composite outsole is a nylon matrix shot through with carbon fiber, blending weight, stiffness, and price in a sole that's as ready to race as it is to spin through a charity ride century. It also resists warping due to humidity, heat, and age, so you'll be wearing the these long after you've worn out and replaced the heel pad. If you've ever lost a buckle to a crash, then you'll also be happy to know that all of the shoes' hardware is also replaceable.

  • Millennium 4 Carbon Composite outsole
  • 1 ratcheting buckle and 2 hook-and-loop strap closure
  • Technomicro synthetic uppers with mesh venting
  • Wide fit

Dedicated Sidi wearer

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: 43 Mega

I've worn Sidi Genius Mega shoes almost exclusively for the past 15+ years. Prior to that? I wore Sidi Genius regular fit shoes ... essentially, I've been wearing Genius shoes since the original buckle, the original sole, and since they only had one Velcro strap. I don't think it gets much more dedicated than that.

Light, stiff, and form fitting, no shoe has ever fit my feet as well, which is why I keep replacing older Genius shoes with newer ones.

My only quibble? The insoles are almost nonexistent. As I've gotten older and my arches have collapsed, I need more a little more underfoot support inside the shoe, so I've had to start using aftermarket insoles.

That said, I've still never found another shoe with an upper that better conforms to the shape of my feet or that cups my heel as well with no slip. Since the way a cycling shoe's upper fits is just as important what's underfoot, it's going to take something amazing to convince me to change.

Wide Sidi shoes

  • Fit: True to size
  • Size Bought: 42 wide

For someone with EE wide feet wide shoes are very appropriate for me and these work perfectly, especially after rides of longer than 2 hours.
