Details

When you come running out of the water you'll be jazzed to see Sidi's T3.6 Carbons hanging from your bike. Their amazingly stiff and lightweight T700 carbon soles are crafted in the same Italian factory as Ferrari and Ducati parts for the ultimate Italian speed pedigree, with just the right amount of toe flex engineered to relieve pressure on the plantar tendon and give you fresh feet for the run. You'll also love how Sidi's supple Lorica uppers and heel cups conform to your feet for a custom fit and incredible comfort. Plus, Sidi's clever no-tongue design, with heel loops and straps that open away from the drivetrain, speed your transitions, while the brushed linings feel great even when you're riding without socks. Grab the T3.6 carbons and be ready for new personal records and podium time.

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.

Fitting tips
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.

Sidi Vent Carbon Sole

Sidi's 3-Bolt Vent Carbon Soles maximize your power transfer, ergonomics and comfort and weigh 38 grams less (each) than Sidi's popular Carbon Lite Soles to keep your shoes nice and light. Made of tough T700 carbon, these sleek soles actually deflect only 1.4mm when 110 pounds is suspended from the tip, which means exceptionally efficient pedaling. Plus they flex just enough to prevent pressure points. And they're called "Vent" because they feature closeable toe vents that let you control the airflow for top comfort. They're also hand made in the same Italian factory as Ferrari and Ducati parts!

Sidi SP Carbon Sole

Sidi's 4-Bolt SP Carbon Soles maximize your power transfer, ergonomics and comfort. Made of tough T700 carbon, they actually deflect only 1.5mm when 110 pounds is suspended from the tip, and Sidi eliminated the need for cleat adapters, which puts your feet 4mm closer to the pedals. These advances maximize your pedaling efficiency and there's also 6mm more cleat adjustment so you can find the perfect position. These soles are lighter too which saves energy. Plus they flex just enough to prevent pressure points and ensure top comfort no matter how far you ride. These sweet soles are also hand made in the same Italian factory as Ferrari and Ducati parts!

The four common cleat bolt patterns.
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!
