The heel retention device tightens the top of the heel cup so that the heel doesn’t slide out during steep climbs or sprints. Each side of the heel can be adjusted independently, for a perfect fit. For a custom adjustment turn the screw towards the + sign to tighten the heel retention device and towards the – sign to open it. Light weight, easy to use, and replaceable. Reinforced SIDI HEEL CUP that stabilizes and supports the heel. Anatomically shaped plastic, reduces heel slip and provides increased power transfer.

TWELVE CARBON COMPOSITE SOLE is made with two different materials blended together, nylon and carbon fibre. It is made out of injected Carbon Fiber in a matrix of Nylon. The Nylon used doesn’t absorb water and doesn’t lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole.

About the Sidi brand

Back in the early seventies, most cyclists just nailed cleats to the soles of their shoes. Of course that sounds crazy to people today. But it sounded crazy to Dino Signori way back then. Sidi’s Genius road shoe is one of the most popular shoes in the professional peloton and it's worn by folks with names like Rominger, Pontoni, and Luperin. But Signori's aspirations aren't limited to the road circuit. The challenge he’s set for himself and for Sidi is to provide every kind of cyclist with the best shoe for the job it road, off-road, cyclo-cross, or even triathlon. Granted, a lot of people might think trying to be the best at everything is crazy. But then again, a lot of people thought nailing cleats to the soles of their shoes was a good idea.
