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.

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!

Sidi's AIR synthetic uppers use a perforated Triathlon-specific material with a plush, brushed interior and minimal seams for sock-free comfort.

Sidi Eleven Carbon/Composite Sole

Sidi's Eleven Carbon/Composite Soles ensure that every bit of your pedal power turns into pure speed. They deflect a mere 2.4mm when a 110 pound weight is suspended from them, and they are designed to flex enough to prevent stress on the Plantar tendons so you ride in comfort and are ready to run, too. What's more, these trick soles won't absorb moisture so your shoes won't gain weight from water after the swim!
