SIDI originated as an artisan laboratory for the manufacture of trekking shoes.
First patent with the rear entry ski-boots.
MOD. MARIELLE VAUTCEL
MOD. GRAND PRIX later named MOD. JOEL ROBERT, with waterproof upper and 6 patented buckles.
MOD. CORSA SPECIAL AGOSTINI
MOD. TITANIUM. The first cycling shoes conceived, projected and produced by DINO SIGNORI revolutionized completely the shoe plate fixing system, giving the opportunity via adjustable screws to find the right position on the pedals, replacing for good, fixed nails.
MOD. PROFESSIONAL, later named SUPER PRO in 1980, was characterized by three important innovations: 1. The new doubled shin deflector made of soft rubber, a result of a particular fusion;
2. New inner laces closure, called FIX LOCK, for stronger adherence and comfort;
3. The velcro closure, adopted on a motocross boot for the first time.
MOD. CECOTTO RACING with upper part made of boarded leather, leather insole stiched on the sole and back zip fastener.
For the first time ever, it is used a nylon sole able to maintain the same rigidity at different temperatures.
The MOD. REVOLUTION. marked an important period for SIDI.
The introduction of velcro instead of laces closure, along with the modern look of the shoe with a nylon sole, revolutionized completely the normal line of cycling shoes, this confirming SIDI as a world leader manufacturer of cycling equipment.
SPENCER MOD. conceived and realized for the young champion: Freddie Spencer.
The first MTB and CYCLE CROSS shoe with the rubber sole was produced.
MOD. ROYAL: the motocross boot with the new raised point protection system determined the evolution of deflector system.
SIDI is absolutely one of the first companies to believe in LORICA®'s quality, a new synthetic material much like leather. It is suprisingly soft for its strength, water repellent and breathing capability. SIDI was the first one to use lorica to produce cycling shoes.
MOD. GENIUS The technical evolution of the quick release pedal led us to study a new closure system instead of velcro, now unable to support the athlete's efforts. So we created the micrometrical buckle, later named MICRO LOCK, the first ever adopted on a cycling shoe, adjustable also while racing.
Tested by famous riders like: Fignon, Kelly and Fondriest.
The MTB line included more models like the famous DOMINATOR and CHALLENGE, with the new two coloured sole compatible with the best pedals on the market. Tested and used by Thomas Frischknecht and Daniele Pontoni.
GENIUS 2 with a new sole characterized by an aerodynamic shape and new design, compatible with any type of pedal on the market. This sole's exceptionally light whilst keeping an optimal balance of rigidity with strength to withstand continuous flexing.
TECNO and MTB FIRE: to exploit all the potential muscle power with the tested MICRO LOCK SYSTEM and the new MICRO LOCK EVOLUTION buckle which guarantees a perfect frontal shoe closure.
TOP ACTION MOD. SRS "Sole Replacement System" is a new system designed and patented by SIDI to allow complete replacement of off road boot soles by the user. It is a new way to change function without the need to change boot.
START MOD. The most advanced road boot for total safety, with many techinical characteristics like:
The new feature of the model TAE FLEXis that the foot of the boot is attached to the bootleg by two seiger for improved flexion of the leg and a more natural and correct posiotion on the footboard.
SIDI SHADOW is equipped with two exclusive closures:
1. The new Spider Buckle is even more Micrometric than before with click-by-click strap adjustment. It is easy to use while cycling and is replaceable.
2. The replaceable, rigid strap closure substitutes the traditional Velcro system and keeps the chosen position.
The MTB collection has also been updated with the model GHOST, with the same technical features as the model SHADOW.
SIDI present the "VERTEBRA" on road boot with its revolutionary "VERTEBRA SYSTEM".
Developed, tested and chosen for greater safety by our top riders, VERTEBRA is a light, comfortable and highly technical boot.
The newly-patented, highly- articulated "VERTEBRA SYSTEM" is the chief support structure of the boot. Each joint of the "VERTEBRA SYSTEM" moves independently.
The "VERTEBRA SYSTEM" shields the back part of the leg and allows enhanced performance.
Sidi has used a new, light, resistant and highly protective material developed in automobile technology to design the first-ever replaceable shin deflector for racing boots.
Sidi was founded in 1960 and, for its 40th anniversary, has decided to present a new cycling shoe.
Energy, a blend of evolution, technology, lightness and harmony.
MTB ACTION SRS
Sidi was founded in 1960 and, for its 40th anniversary, has decided to present a new MTB shoe, with its revolutionary Sole Replacement System.
Mtb Action Srs, a blend of evolution, technology, lightness and harmony
ENERGY The closure on the instep on the Energy and the mtb Action Srs models has been modified and both now feature the Instep Closure System.
Ergonomically shaped it can be positioned to more evenly and securely position the loads across the top of the arch. Replaces the need for a high instep adaptor.
VERTEBRA RACE Continuously researching new technological solutions to enhance rider safety:
Adjustable calf system
The internal plate is adjustable to fit snugly to the dimension of the calf and is also entirely replaceable. The regulation of the A.C.S. is based on screws that shift laterally inside the plate holes. A further adjustment of the calf is possible by removing the screws and the ACS and using the holes on the inside: simply lift the adhesive internal padding and move the inserts from one hole to the other, then close the open holes with the plastic plugs you find in the box of the boots.
The plate is made of two different materials: a rigid one to support the boot and a heat-resistant one to protect the leg from exhaust heat.
Note: substitute the plate before the contoured part wears down to the screws
VERTEBRA 2 The patented Vertebra System has been redesigned to ad feature the Adjustable Calf Systemwholly replaceable and adjustable to the size of the calf muscle.
ERGO 1 CARBON
· Carbon sole. Ego 1 carbon is currently the only cycling shoe on the market, to feature a nylon sole with two replaceable 100% pure carbon inserts positioned in the metatarsus and arch support areas where the automatic pedal is fixed. The carbon inserts cover 60% of the surface of the sole, giving more rigidity than nylon but, at the same time, also providing increased flexibility and comfort in the toe area of the shoe, which allows improved blood circulation when the rider pushes on the pedals.
ERGO 1 CARBON
Security System. The Velcro® strap on the front part of the shoe features recessed (hidden) opposing polymer teeth that hook onto each other when the strap is closed.
This feature makes the closure more secure and the Velcro® unmoveable..
CERAMIC SCUFF PAD.
The first ever use of ceramic on a motorcycling boot.
The ceramic in the scuff pad does not wear out and allows enhanced sliding.
HI-TECH CARBON FIBRE SOLE
It is a nylon sole with two replaceable inserts positioned in the metatarsus and arch support areas
The inserts are produced in low-density material reinforced with 40 % carbon fibre. A light, very rigid and temperature-resistant sole.
SYSTEM FLEX - The Flex system, with its two circlips that attach the foot of the boot to the bootleg, improves leg flexation. A second joint has been added to bootleg itself, above the ankle joint. This technical improvement has been created for more flexibility; a more comfortable fit and increased adjustment of the boot leg. In this way, the rider can adjust the boot strap at the calf to his personal preference and achieve an improved fit.
BUCKLES - It adopts four micro adjustable buckles that work independently from each other, allowing the boot to fit all shapes of feet
BOOT LEG - The boot leg is entirely assembled with screws and totally replaceable.
Suitably studyed for the SUPERMOTARD, constructed of a special blend that withstands wear and tear exceptionally well, easily replaceable and compatible with the SRS system.
HEEL CUP SYSTEM (HCS)
For cyclists with a thin ankle Sidi has thought of, created and patented a mechanism that tightens the heel so that it doesn't come off during the harder parts of a race or a sprint.
Made in thermoplastic it can be easily replaced or removed.
FULL CARBON SOLE
The sole in full carbon that Sidi presents is unique and rare in its kind, because it's not completely rigid. This is due to the soles different thicknesses. Planned, projected and made to satisfy whomever requires a sole that is rigid but that does not compromise the foot's blood circulation, thus guaranteeing excellent comfort and great performance.
The new sole, that thanks to its thinness brings the foot closer to the pedal axis, has a replaceable rubber heel and an anti-slip insert on the top.
COMPOSITE CARBON SOLE
The Carbon Composite Sole is made with different thickness levels to provide a slight amount of flex while retaining excellent stiffness and power transfer in the body of the shoe.
The Carbon Composite sole is made out of injected Carbon Fiber in a matrix of Nylon. The Nylon used is preferable to standard Nylon because it doesn't absorb water and doesn't lose rigidity in hot or humid weather or as it ages.
It includes an anti-slip insert at the toe and has a replaceable rubber heel pad.
MTB SRS CARBON SOLE
The heart of the patented Mtb Srs carbon sole is a pure carbon insert reaching from the heel to the toe. The carbon insert as well as the replaceable Dragon SRS tread are bolted to a narrow, durable nylon frame. In order to achieve maximum shoe life the carbon inserts as well as the Dragon SRS tread are easily removable and replaceable.
In addition an optional toe guard can be installed using the same screws as the insert.
A polyurethane anti-slip insert has been positioned in the Metatarsus area.
The sole's inserts and the screws are available as spare parts.
It is toe spike compatible.
ADJUSTABLE HEEL RETENTION DEVICE
improves fit by closing the back of the shoe more securely around the rider's ankle.
The heel retention device tightens the top of the heel cup so that it doesn't slip during steep climbs or sprints.
It can be adjusted with two small screws that work independently from each other.
MILLENIUM 3 SOLE
The MILLENIUM 3 sole is constructed out of injected carbon fiber in a nylon matrix. The infusion of carbon fiber gives the sole more rigidity.
It is more durable and less susceptible to changes in stiffness resulting from prolonged usage and changes in temperature.
The MILLENIUM 3 sole features the replaceable non-slip heel pad.
To facilitate cleat replacement, the Millennium 3 sole features a 10 mm horizontal and vertical cleat alignment scale molded into the sole as well as the Look Memory Eyelet.
The latest in technology combined with the great skill and workmanship of the Sidi European based factory technicians blend in a whirl of fresh solutions satisfy the rider’s safety and comfort
The rear upper is made up of the following mechanisms: TECNO CALF TENSIONER, TECNO SHIN TENSIONER and ANKLE SUPPORT BASIS.
The TECNO CALF TENSIONERmechanism adjusts the leg circumference. Placed in the back, it works through a nylon wire that hooks directly to the shin plate. The TECNO CALF TENSIONER is replaceable and it’s available in different sizes to fit around the calf muscle.
TECNO INSTEP TENSIONER
The Vortice features an additional fastening system on the front part of the foot, on the instep. It consists of a wrap-around fascia which can be precision adjusted by the TECNO INSTEP TENSIONER mechanism that was proved critical in rider safety by the previous model Vertigo Corsa.
SHOCK ABSORBING HEEL CUP
A polyurethane shell holds a shock absorbing insert, visible from the outside through 4 small slits that mark out the look of the heel. The shell is mobile as it’s fixed to the boot by 2 screws that allow 3 mm of impact movement.
The shin plate is made in nylon and it is inserted on a polyurethane frontal support. Both parts are replaceable.
The toe slider is made in nylon reinforced with fiberglass. It is fitted with a new air intake and an innovative alloy insert.
RACING SRS SOLE
The sole is constructed of a polyurethane and rubber blend. It features a removable insert in front of the arch area where much wear and tear normally occurs due to sharp metal brake pedals and shift levers.
CARBON LITE SOLE
Carbon Lite Sole has been developed using a mix of innovative composite materials which maximizes the stress resistance of the sole but making it lighter.
It is offered with a simple design made with thin lines attentive to the structural and aerodynamic look. The sole has been engineered for the high-performance, high-mileage cyclist who requires a sole that is rigid but does not compromise the foot's blood circulation, guaranteeing comfort, foot health and great power transfer.
For walkability, the Carbon Lite Sole includes an anti-slip insert at the toe and a replaceable polyurethane heel pad.
The Carbon Lite Sole is compatible with the best pedals on the market. To facilitate cleat replacement, the Sidi Carbon Lite sole features a 10 mm horizontal and vertical cleat alignment scale molded into the sole as well as the Look Memory Eyelet.
Vent Carbon Sole
New sole developed by SIDI engineering department . It is lighter than the previous one.
The vent inserted at the very top of the sole, when open, gives a good and comfortable ventilation.
Air will flow through these predisposed channels until exit an open exhaust towards the middle of the shoe. The air-vent can be open or close as need it.
The “Vent Sole” is built to give a light flex towards the nose of the shoe and maintaining an excellent stiffness throughout the body-shoe.
The Vent Carbon Sole is compatible with the best pedals on the market. To facilitate cleat replacement, the Vent Carbon features a 10 mm horizontal and vertical cleat alignment scale molded into the sole as well as the Look Memory Eyelet.
New design and improved construction of the boot as well as the Adjustable Calf System.
The calf plate features an inner double adjustment, which allows to widen the circumference of the boot and accommodate even wider calves.
WIRE CARBON VERNICE
Innovative technology for the Tecno 3 dial used as a closure system, it wraps the whole shoe adapting the upper to the shape of the foot.
Tecno 3 system also closes model Mtb Drako carbon srs which features a new MTB SRS Carbon Ground sole. The SRS Carbon Ground sole is made of lightweight carbon and has four inserts screwed in easily replaceable in case of wear (Sidi patent).

Sidi Size Guide
*Customers switching to Sidi Shoes or from Sidi;s more than 5 years old, may not wear the same size. All Sidi's, except for winter shoes, are built on the same last, but differences in patterns and materials so keep this in mind when switching between Sidi models. Every Sidi Shoe (except triathlon models) from 2002 onwards is stamped with its size and last type (and M indicates Mega or W indicates women's), Usually on the tongue.
Standard Width is considered as a D width
Mega = EE shoe fit 4mm of extra space across the ball of the foot. If you have high-volume orthotics you may feel more comfortable in a mega shoe.
Women fits - "Women specific" shoes are a narrower and smaller version of the regular fit option. The heel and ankle areas have also been narrowed.
How do I know if its a good fit?
Some people have narrow heels, if you know this to be true we recommend getting a shoe with a heel retention device. This will allow the heel to be narrowed.
Is it too small? If you stand up with your shoes on and your toes are touching the front, your shoe is small. You don't want any toes touching the front of the shoe, this will create hot or numb toes on long rides. You want to be able to wiggle your toes a bit, but not feel like they are "sloshing around"
Tip* Try on your new Sidi Shoes with the cycling socks you normally wear
If the shoe doesn't fit? Don't worry, we offer a 1 free resize policy to make sure you are very comfortable on your bike
