Item # SID004V

The standbys.

For 2015, Sidi's old standbys, the Genius Fit Carbon Shoes, return virtually unchanged from their previous iteration. The predecessors of these shoes have been with us throughout our entire cycling careers and, with the option of replacing all the hardware — from the heel pad to the buckle — the latest bearers of the Genius standard are sure to enjoy the same longevity.

The Genius Fits use Sidi's beloved ratcheting buckle for retention. Is "beloved" to strong of a word to describe fastening devices on cycling shoes? Maybe. But after tens or even hundreds of thousands of miles together, we suggest that the average cyclist's bond with Sidi's buckle system is more than simply utilitarian. With wire dials (originally a Sidi innovation in the early 80s) and laces enjoying a fashionable renaissance in the peloton, it's easy to lose sight of the fact that virtually any cyclist pedaling in anger during the past three decades relied almost exclusively on this buckle—or a buckle largely based on it—to fasten their cycling shoes. So "beloved"? Yeah, we're comfortable with it.

Given the buckle's history, 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 that persists long after the hook-and-loop filaments have been blunted down to wilted, apparently useless shadows of their former selves.

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. If you've ever lost a buckle to a crash, then you'll also be happy to know that all of the upper's hardware is also replaceable.

The Millennium 4 Carbon Composite outsole isn't of the current crop of full-carbon that now defines the $200 shoe range. Instead, it's 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. The important takeaway here is that, for all those years we've been relying on Sidi's buckle to keep our feet strapped to our shoes' soles, this has been the sole we've been strapped to. Comfort, stiffness, durability: it's all there. We know because we've tested it for years on end, so all of the above isn't just catalogue palaver, it's a reflection of our experience.

  • The classic cycling shoes we've all raced and trained on
  • Proven stiffness and durability of the Millenium 4 outsole
  • Synthetic uppers conform to your foot without getting sloppy
  • Traditional buckle and strap fastening system
  • Sidi's Genius line largely defined the course of cycling shoe innovation for the past few decades

great so far

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

after the first couple long rides the shoes broke in and i was comfortable. these are great so far and i have zero complaints, theyre stiff but coomfortable and seem to be well made. i guess time will tell...

I just bought myself a road bike and needed a pair of shoes. Relying previous experiences with MTB SIDIS I didn't hesitate to choose them again. (5 years and counting with the same pair)
They feel very comfortable (6 hour rides to justify this) They are great lookin (bright color to increase safety). They are quality crafted. Besides all that I got them for a bargain price in competitive cyclist.

Love 'em!

  • Size Bought: 46.5

Picked up the white/red/black to replace my 10 y/o Sidi road bike shoes. I loved my old pair because they had the 3 velcro straps, for easy adjustment.

I found this model to be lighter and stiffer than my previous pair of Sidis. I don't know if the stiffer feeling is a good thing yet, but certainly each time I wear them, they soften up and seem to mold to my feet.

This model seems to have less material and is better fitting than my previous model.

I wear a size 12 or 12.5 in regular shoes and got the Sidis in a 46.5. I can barely fit an index finger behind my heel when the shoes are on and don't find my toes are crunched.

I've worn these on long climbs, on long rolling rides, and find they get more and more comfortable the more I wear them. i have about 500 miles on them now and am very happy with the purchase. The white/red/black looks awesome and will match any kit. I contemplated the Yellow fluo also. I definitely would not recommend the all black color because that is simply too boring.

Great Shoe

Excellent fit. Have tried many others, including the custom molded "heat-fit" Shimano, and this is by far the best fit for my wide foot. Literally no hot spots. I didn't think that was possible.
Did not need to order a size up since the wide version takes care of my typical sizing problems.

Great shoes

I have been using Sidi shoes for decades. Whenever I stray I come right back to Sidis, and typically buy the most expensive model. Still my feet hurt. (I have multiple foot problems.) I cycle 50-60 miles/day and with sore feet, it is a challenge.
I ordered these shoes, but in a size larger. (I wear a 12/47. I ordered a 13/48.) They feel a bit large, but my feet are happy! I use Spenco insoles, which are better than my custom insoles from a pedorathist. My feet are happy for the first time in decades. I have to tug down on the straps a bit, but they fit fine. The key is both width and height clearance. And the color (screaming yellow) matches my jersey, helmet, and gloves. I ordered a second pair. These are cheaper than my other Sidis, and a tad heavier, but who cares: my feet and wallet are happy.
CC is a great company and I will continue to buy from them. Thank you, CC.

This were an upgrade, mainly got these, due to the carbon sole and the way they looked, they just appeal to me. To be honest I expected them to be more on the comfort side but that was not the case, they felt as comfortable as my SIDI Taurus were. The extra additional strip of polymer teeth to ensure secure locking does work well, I do love the ratcheting buckle, keeps the shoe in place, specially while sprinting, or pushing that climb. Overall, shoes were an upgrade on a few levels, an honorable mention was the extra ventilation made the overall comfort better, only reason I did not gave a 5 star rating was due to the non comfort notable upgrade on the foot bed, from going from a lover rank shoe to these.
