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.

To mount your pedal cleats to your shoes (cleats are included with new pedals and sold separately), they must have matching bolt patterns. There are four configurations (diagram) used on cycling shoes, 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 what pattern your shoes use, please ask us. We're here to help!

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 Carbon SP sole.
Sidi's hand-made Carbon SP soles optimize your power transfer and protect your feet. These amazingly stiff platforms deflect just 1.4mm when 110 pounds is suspended from the tip, plus a small degree of toe flex is built in to relieve stress on the Plantar tendons so you pedal comfortably mile after mile. Also impressive, the Carbon SP soles are hand made of T700 carbon in the same Italian factory that makes Ferrari and Ducati parts!
Sidi's Soft Instep Closure straps
Sidi's Soft Instep Closure System features wide sections on the straps for an anatomical fit that hugs your feet and to spread the pressure for maximum power transfer and comfort.
Sidi Tecno 3 buckles
Sidi's Tecno 3 buckles make it super easy to fine-tune how tight your shoes are even when you're riding. The low-friction wire laces tighten and loosen freely so you can dial in the perfect tension and enjoy total comfort on every ride.

Sidi's Adjustable Heel Retention DevicesSidi's Adjustable Heel Retention Devices provide a snug, customizable fit around your heels and maximize your pedaling power. Simply turn the screws in the back of them to tighten or loosen the fit and keep your feet comfortable and in place.

Fit Relievers are tiny cuts in the tongue that reduce bulk and keep it from rolling over and digging into your foot.
