TWELVE CARBON COMPOSITE sole is made with two different materials blended together, nylon and carbon fiber, injected carbon fiber in a matrix of nylon. The composite sole doesn’t absorb water or lose rigidity in hot or humid weather or as it ages. The result is a significantly lighter and stiffer sole.
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. SOFT INSTEP 4
TECHNO-3 PUSH dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit.

Like most SIDI small parts, the TECHNO-3 PUSH buckle is serviceable and replaceable. It can be adjusted while riding, with an innovative button which can be pushed to lift the buckle and facilitate the adjustment.
