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 allowing for greater preformance and comfort when riding hard.

SIDI’s famously reliable, duarable 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 the majority of SIDI small parts, the TECNO-3 SYSTEM is serviceable and replaceable.

The CARBON COMPOSITE 20 SOLE is in nylon and injected carbon fiber. The nylon keeps the technical features unchanged over time. The FAST are equipped with a Non-Slip, Replaceable Polyurethane Insert in the heel that improves walking.
