ALBA 2 MEGA FITS LIKE A GLOVE
![](https://www.sidi.com/img/cms/Alba%202/SOFT-INST-CLOS-SYS3-ALBA2.jpg)
Soft Instep Closure System 3
THE SOFT INSTEP CLOSURE SYSTEM is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The SOFT INSTEP CLOSURE SYSTEM is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. The system eliminates the need for the High Instep Extender. The SOFT INSTEP CLOSURE SYSTEM is replaceable.

TECNO-3 SYSTEM
SIDI’s TECHNO-3 SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit. SIDI’s famously reliable and replaceable closures are improved by an all new proprietary SIDI Wire material that is completely non-binding for intuitive and effortless on- the-fly adjustments. Like most SIDI small parts, the TECNO-3 SYSTEM is serviceable and replaceable.

SIDI HEEL CUP

REPLACEABLE HEEL PAD
For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.

MILLENIUM 4 CARBON SOLE
The MILLENNIUM 4 CARBON COMPOSITE Sole features injected carbon fiber in a matrix of Nylon, providing more rigidity than a standard nylon sole. The MILLENNIUM 4 CARBON COMPOSITE Sole is also more durable, completely non water- absorbent and mechanically stable, meaning it’s less susceptible to changes in stiffness resulting from aging, prolonged usage, and changes in temperature or humidity. The MILLENNIUM 4 CARBON COMPOSITE Sole uses a standard 3-hole drilling pattern for compatibility with the best pedal systems available, and includes a printed 10 mm lateral and fore/aft cleat alignment scale on the sole for easy cleat alignment and replacement.
The MEGA fit also gives those who have a slightly wider foot to comfortably wear Sidi cycling shoes
- 4mm wider across the ball of the foot
- more volume, a high instep and a wider heel cup
- mega lasts are EE o EEE width
