The combination of the Suola Twelve Carbon Composite sole and comfortable top result in the best pedal efficiency and optimal fit. The Techno-3 system adjusts the top of the shoe to the shape of your feet.

Extensive explanation size in cm
The size denoted in cm tells you how long the shoe is. This size was taken on the inside of the shoe measuring from the heel to the toes. In order to determine what size you’ll need, you can measure your own foot. Do this by placing a piece of paper on the floor tucked against the wall. Stand on the paper with your heel against the wall. Draw a line at your big toe. Measure the distance between that and the wall, and add approximately 5 mm. The number of centimeters is the size in centimeters found on our website. Which specific EU/UK size you need can differ between brands. This is because each brand uses their own boot tree, causing the shoe to be bigger or smaller than the size would suggest. This is why we’ve added the size in centimeters for all of our shoes. We’ve also categorised our shoes in three different groups: narrow, medium, and wide. In order to determine the width of your foot, you can use this table. Read all about it on our blog!

Detailed product description

Suola Twelve Carbon Composite
The sole is made using a combination of carbon fibre and nylon. The carbon fibres provide the soles with improved stability, durability, and are more resistant to changes in rigidity of the sole due to prolonged use of temperature changes.

Soft Instep 3 system
Anatomically shaped, comfortable strap across the foot combined with a soft and thermoplastic upper. The strap evenly distributes the pressure across the foot arch, can be adjusted on both sides to create a perfectly centred fit, and is replaceable.

Techno-3 system
The new Techno-3 mechanism allows you to secure the shoe across the entire length, enabling it to fully form to the contours of your foot and creating a personalised fit. The reliable and replaceable retention system has been further improved with a new wire, making it easier to adjust the fit on the go.

High security velcro strap
The high security velcro strap has plastic teeth that interlock when the strap is closed. This makes it safer and the strap will not move.

Adjustable Heel System
Reinforced upper heel component which improves the fit of the shoe by making it follow the contours around the ankles more closely. The system also tightens the upper half of the heel cup, preventing any slippage during a heavy climb or sprint. Two independently adjustable screws allow you to loosen or tighten the fit at the heel.

Sidi Heel
Reinforced heel which keeps your foot in an optimal position, preventing the shoe from deforming over time due to stresses or prolonged pressure.
