MICROFIBRA TECHPRO is a microfiber PU Made in Italy. It is considered a highly technological and innovative, eco-friendly leather suitable for technical and sports products which require high performance levels. TECHPRO MICROFIBER incorporates features of resistancy, stability, lightness, water-repellency and eco-friendliness.

TECHPRO MICROFIBER has a Hydro and anti-mold treatment, which eliminates the onset of molds and bacteria.

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.

SIDIs 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. SIDIs 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 BUCKLE is serviceable and replaceable.

The ADJUSTABLE HEEL RETENTION DEVICE reinforces the top of the heel cup and improves the fit by closing the back of the shoe securely around the riders heel. The heel retention device tightens the top of the heel cup so that the heel doesnt 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.

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 doesnt absorb water and doesnt lose rigidity in hot or humid weather or as it ages.The result is a significantly lighter and stiffer sole.
