Like most small SIDI parts, the TECHNO-3 PUSH buckle is repairable and replaceable. It can be adjusted along the way, thanks to an innovative button that can be pushed to lift the buckle for easy adjustment.SIMPLE TECNO-3 PUSHThe central mechanism, SINGLE TECNO-3 PUSH SYSTEM, creates a perfect balance of tension between the inner and outer side of the shoe.The symmetrical mechanism guarantees an excellent closure that adapts to every instep.An innovative button added to the monofilament buckle, if pushed, lifts the buckle for easy adjustment.ADJUSTABLE HEEL SUPPORTThe ADJUSTABLE HEEL RETENTION DEVICE reinforces the top of the heel shell and improves the fit by closing the back of the shoe around the rider´s heel.

For custom adjustment, turn the screw toward the + sign to tighten the heel retainer and toward the – sign to open it.

The vent can be opened or closed for 4-season comfort.WIND CARBON SOLEThe VENT CARBON outsole is handcrafted exclusively from carbon fiber in a weave pattern oriented at opposite angles that maximizes stiffness while allowing a small degree of controlled flex in the toe area. This carefully designed flexibility biomechanically relieves stress on the plantar tendon and helps promote circulation.The VENT CARBON insole features a standard 3-hole drilling pattern, a printed 10mm side and fore/aft stud alignment scale and a shape memory lug for easy stud alignment and replacement.
