Just because Sidi's Genius 6.6 Vent Carbons took multiple victories in the Tour de France and Giro d'Italia doesn't mean Sidi wouldn't make them even better. Thanks to their T700 carbon soles, these shoes (the Megas are the wide-fit version) are light and stiff for awesome pedal power. The closeable vented soles provide airflow, while the breathable Lorica/mesh uppers offer luxurious comfort and keep you cool and dry. Plus, Sidi's Soft Instep Closure System, Caliper buckles, High Security Velcro straps, and Adjustable Heel Retention Device provide a truly custom fit that keeps you feeling great on even your most epic rides. What's more, Sidi's handmade carbon soles are crafted in the same Italian factory that makes Ferrari and Ducati parts so you know these shoes are fast.
Fitting Yourself to Sidi Cycling Shoes
There is no substitute for a perfect fit. Your shoes are the most important contact point between you and your bike, affecting power, comfort, and providing that locked-in feeling of oneness with your bicycle.
Try shoes on at the end of the day — your feet swell by at least a half-size as the day progresses, and as much as a full size on hot days.
Stand up. Feet expand under pressure — standing up will give you a better sense of how your shoes will fit under pedaling pressure.
Bring the socks and orthotics you ride with — they have a tremendous influence on foot volume and fit.
Be patient! Non-leather cycling shoes do not stretch over time — how they fit in the store will be how they fit, period. However, as the shoes warm up from body heat the uppers will become more pliable and conforming. Give your shoes at least 10 minutes to heat up, and readjust the closures to accurately gauge how they’ll feel mid-ride.
Foot measuring devices typically measure length and width only, and do not account for overall shape or foot volume. It’s imperative that you try on shoes a half-size larger and smaller than your measured size, for confirmation of proper fit.
How Sidis are sized
Sidi half sizes are 3mm longer, with slightly increased toe box volume. Full sizes are 6mm longer, with proportionally greater volume.
Standard-size Sidis roughly correspond to a D width on the industry-standard Brannock sizing scale.
Mega sizes are cut with more material throughout, and larger-volume heel cups. Mega sizes roughly correspond to an EE/EEE width on the Brannock sizing scale.
Narrow sizes are cut with less material throughout, and narrower, lower-volume heel cups. Narrow sizes roughly correspond to a B/C width on the Brannock sizing scale.
Women’s Sidis have a more tapered shape and lower volume than standard or narrow-width Sidis. Women with consistently wide or narrow feet, from heel to the forefoot may experience better fit in Sidi standard or narrow widths.
In order to mount your pedal cleats to your shoes (cleats are included with new pedals and sold separately), the cleats and shoes must have matching bolt patterns.
There are four cleat configurations found on cycling shoes (diagram): SPD-R, Look/SPD-SL, SPD and Speedplay. Road shoes feature one, two or even three of these. Off-road shoes usually use the SPD pattern. If you're unsure which cleats your shoes require, please ask us. We're here to help!
Sidi's Vent Carbon soles optimize your power transfer and ensure top comfort, too. They deflect just 1.4mm when 110 pounds is suspended from the tip. Plus, a small degree of toe flex is built in so you enjoy comfort mile after mile.
Another great feature is the built-in adjustable vents at the front of the soles that can be set to let in or seal out the air. When open, the vents work with the channels beneath the perforated footbeds for excellent airflow and comfort.
Lorica is a lightweight, flexible, water repellent and breathable material made of the finest microfibers. It's amazingly durable and, like leather, it improves with age.
Sidi's Adjustable Heel Retention Device provides a snug, customizable fit around your heels and ensures maximum pedal power. Simply turn the screws in the back of the Retention Device to tighten or loosen the fit and eliminate slippage.
