Sidi Alba 2 racer shoes with carbon composite sole, specially designed for women.

Models are narrower around the heel and front which gives a better fit.

The top is made of Politex which consists of several layers that are laid on top of each other to get the best properties from materials in the form of, e.g durability, extensibility, etc.

The top layer consists of a clear film, which keeps the color clear and glossy for a long time.

The back of the shoe is made extra hard so that the shape cannot be changed, even during hard workouts. That way, it holds the foot well.

The shoe closes with Sidis Techno 3 system which is a swivel buckle which makes it possible to adjust how tight the shoe fits, very precisely. The shoe also closes with velcro straps later on.

The wire on the swivel clamp is combined with the Soft Instep 3 system, which is a wide strap that ensures distribution over a larger area. The strap can be adjusted so that it fits exactly where you want it.

The sole is Sidi's Millennium Carbon Composite sole which consists of carbon and nylon. It is very stiff and provides for god power transmission. At the back of the sole is a heel which makes it easier to walk in the shoe. This can be replaced if it gets worn.

The shoe fits all common clamp systems for races, such as SPD-SL, Look Keo, Look Delta, Speedplay and more.
