SIDI’s TECNO-3 SYSTEM dials in fit along the upper part of the feet 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 TECHNO-3 PUSH buckle is serviceable and replaceable.
It can be adjusted while riding, thanks to an innovative button that can be pushed to lift the buckle and facilitate the adjustment.
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 rider’s heel. The heel retention device tightens the top of the heel cup so that the heel doesn’t slide out during steep climbs or sprints.
For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad. WIRE’s heel pad has a new design and it is very light.
The VENT CARBON Sole is handmade exclusively of carbon fiber in a weave pattern oriented at opposing angles that maximize stiffness while allowing for a small degree of controlled flex in the toe area. This carefully designed flex biomechanically relieves stress on the plantar tendon and helps promote circulation.
The VENT CARBON Sole features a standard 3-hole drilling pattern, printed 10 mm lateral and fore/aft cleat alignment scale as well as the Look Memory Eyelet for easy cleat alignment and replacement.
