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 BUCKLE is serviceable and replaceable.
Reinforced heel cup
The MTB RS17 SOLE consists of a Nylon and PU blend. This sole is lighter than the traditional competition sole and has been updated with a more aggressive tread pattern and a replaceable toe tread insert.
Regular "D" width.
INTEGRATED HEEL CUP
The HEEL CUP is integrated, with new design and light weight, reinforced to avoid deformations after prolonged efforts and pressures.
Anatomically shaped, it stabilizes the foot while pedaling. The reflex inserts on the heel provide greater safety to the athlete on the road, helping to signal the presence of the cyclist in conditions of poor visibility.
