Comfort is a right.

Comparing the Genius 6.6 Vent Carbon Shoes to Sidi's flagship Wire shoe, you're bound to uncover numerous shared design features. You'll find the same carbon fiber sole, the same adjustable Heel Security System (HSS), and an identical intake vent system. In fact, the two really only part ways on a few points-- aesthetics, a closure system, and price.

Hailed as Ivan Basso's favorite shoes, the Genius 6.6 features a more traditional exterior design than the Wire. This is most apparent when examining the shoes most predominant aesthetic features, the closure system. In lieu of the Wire's Techno 3 buckle system, the 6.6 opts for Sidi's tried-and-true, two-way ratcheting Caliper Buckle. Assuredly, you've seen the Caliper Buckle imitated by lesser shoemakers, however, this design was invented by Sidi decades ago. The system allows for incremental adjustments, either pre-ride or on-the-fly, and it's further complimented by Sidi's take on two hook-and-loop straps. Not your standard Velcro, these two volume-controlling straps feature Sidi's patented High Security Velcro. So, you'll never experience any fraying, wear, or loosening of the Velcro over any period of time. Together, as a system, the three-point closure system ensures that you get the perfect fit every single time that you buckle up for a ride. And for those who prefer as snug a fit as possible, the shoe's tongue and instep strap have both been padded generously to allow for supreme comfort with tight buckles.

As we stated, the Genius 6.6 shares the same sole as the Wire. Based off of the Ergo 3, the 6.6 sole features the superlative vented carbon fiber. It shares the same construction method that Sidi developed with its Carbon Lite sole, yet Sidi has removed around 38 grams in the process. Even with the weight savings, you'll get the same kind of stiffness and razor sharp power transfer you've grown to expect from Sidi. And like Garneau's Ergo Air system, the vent inlet is at the toe. However, Sidi's system can be opened or closed depending on the temperature and your preferences. This, you can do on the bike if necessary. The airflow moves underneath and through the insole to cool your feet in sweltering summer temperatures.

Also returning from previous top-shelf offerings is Sidi's vastly improved Heel Security System (or HSS) to keep your foot positively planted in the shoe. By means of a small allen key, it's an adjustable, rigid composite band that closes the shoe more securely over your heel to anchor it in place around your Achilles. So, no matter how much power you're pouring into the pedals, your heel will stay in place inside the shoe. It's a detail that allows you to cinch down the straps of your shoes less tightly -- giving you more comfort along with more security.

With a degree of engineered flex in the Vent Carbon Sole, and a secure and slip-free heel, you won't have to worry about hot spots. And you especially don't have to worry about heat in the rest of your feet, either. With the Genius' combination of Lorica microfiber, ballistic mesh, and new Comfort Fit insoles, you'll receive comfort, a perfect fit, ample ventilation, and season-after-season durability.

The Sidi Genius 6.6 Vent Carbon Shoes are available in the color Black Vernice/white and in whole and half sizes from 39 to 48. Most sizes also have an Mega option available for those requiring a high-volume shoe. Please note that these shoes are only compatible with standard, three-hole road cleat systems.

Just like Ivan Basso

  • Familiarity: I gave it as a gift, but have feedback to share
  • Fit: True to size

Bought these for my dad who has worn a pair of Sidi's for about five years this pair. So far he has worn them on a couple of rides and says that they fit very similar to other Sidi's he has worn. He loves how the venting and how well air moves through. All in all it is a great quality Italian shoe; stiff, lightweight and well made would recommend this product.

Great Italian Quality

  • Familiarity: I've put it through the wringer

This is a superb pair of shoes. I purchased a pair back in the summer and love the quality and fit of these. They are very ventilated and i do not get hot spots when wearing them. I am a US size 11 and the 45.5 fit perfectly. They stay nice a snug on the feet and the straps are very easy to adjust. This is my second pair of Sidi's. The first pair lasted me 8 years so they have awesome quality. Just what you would expect from an Italian shoe.

Too Big!!

  • Familiarity: I returned this product before using it

I recently found that normal shoes do not fit me well. I have wide feet. After trying a size 44 at a store I decided to order the 44 MEGA. When I received them I realized that they were too big. Competitive Cyclist does not have the 43.5 MEGA in this style so I order the Sidi 5 Carbon and I will see how they fit. They look like a really good shoe very disappointing they don't have my size.

The Best Road Shoe

I have ridden Sidi's for the last 5 years. My first pair were Genius 5. I would rate them fair. These Genius 6.6 are excellent. They have addressed all the issues I had with the 5's. they are extremely well vented., they provide great side support where the 5's had none. The wide size fits my toe box perfectly without allowing me to swim in the rear of the shoe. This shoe actually fits American feet, not just Italian feet! I will keep buying these. 5 stars.
