The best just got better.

There's little doubt that Sidi is the world's best-selling cycling shoe, and the Sidi Genius Fit is destined to be one of its most popular models. Similar to the Genius 5 Pro, the Fit uses the same design, only with both technology and material upgrades.

Sidi constructed the uppers of the Genius Fit shoes from its Technomicro material. Essentially, this is a composite microfiber that's created from strands that are so fine that each one is less than one-thousandth the thickness of silk. These fibers act like a natural leather skin, only with the advantage of increased strength, soft texture, and light weight. Water-repellent, quick-drying, breathable, and permeable to water vapor, it's obviously ideal for shoe uppers. It's abrasion- and mildew-resistant, as well, making it far 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.

At the outsole, we find that Sidi went with its Millennium 4 Carbon Composite for the construction. If you're familiar with Sidi, you're certainly familiar with the Millennium 3 composite, and well, this replaces that iteration for pretty obvious reason. Designed with a nylon matrix that's been injected with strands of carbon fiber it's 37% stiffer than nylon alone. The material is non water-absorbent, and it's resistant to changes in stiffness from prolonged use, age, or temperature. It features an anti-slip toe and a replaceable polyurethane heel pad.

Sidi's hallmark Caliper Buckle has been incorporated for retention. This two-way ratchet allows for micro-adjusts of the strap pressure in order to ensure that the fit of your upper won't be too loose or too tight. It's mated to a Soft Arch Compression Strap that evenly spreads the upward stroke pedaling forces across the top of your foot. The buckle provides four-clicks per uptake along with half-click releases. Essentially, this means that you're able to precisely tension the pressure of the strap. No other system provides more of a gentle and precise customizable fit. You also get the precision of two High Security hook-and-loop straps for volume adjustability. Its padded tongue with fit "relievers" is one final small (but important) detail that helps deliver unparalleled comfort.

The Sidi Genius Fit Shoes are available in the color Black and in odd and even sizes from 38.0 to 48.0. Additionally, Sidi is providing these shoes in a Wide design for odd and even sizes between 40.0 and 46.5. Please note that these shoes are only compatible with three-hole road cleats.

Love these shoes

  • Familiarity: I've put it through the wringer

Purchased a wide pair and what a revelation! My old shoes where narrow in the forefoot area and after about two hours my feet ached. These seem a bit large when I start riding but after about 30 minutes, they seem just right. Combined them with Shimano clips and they afford great control clipping in and out. Plus they look pretty good. Expensive but worth it.

Unanswered Question

Will the new Speedplay v.2 cleat system work with this shoe? It's not listed on the Speedplay compatibility chart.

Just what I needed

Ordered the wider fit which is too wide when I start and perfect after I have been on the bike for a while. Got tired of trying normal shoes with a supposedly wider last for the toe box and just went bigger. It has worked. Seems like a solid shoe with no issues which at this price I would expect. Curiously after a break of 20 years I found the most challenging part of riding was the clip in pedals and I had a really hard time with the more narrow shoes these replaced. With these shoes I just click right in. There is a difference in the wear strip in the front which may be doing it. Managing high traffic situations is now much more comfortable.

Sidi Genius Fit Shoes

  • Familiarity: I've used it several times

First time buying Sidi. Size fits nice and was consistent with my previous Shimano/Bontrager sizes. Soles seem slippery compared with my previous road shoes (anti slip toe piece feels chinsy??? would have been better with a replaceable rubber piece). Shoe is comfortable but will replace insole with a better one.
