The SIDI Ergo 5 are general use comfort/performance cycling shoes with a composite carbon/nylon sole. The SOFT INSTEP 4 CLOSURE SYSTEM dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot. SIDI HEEL CUP is a reinforced anatomic cup that stabilizes and supports and protects the heel area. As usual for SIDI shoes, replaceable parts are part of the design.
TECHNOLOGY:
TWELVE CARBON COMPOSITE sole is made with blended, nylon and carbon fiber, injected carbon fiber in a matrix of nylon. The result is a durable and significantly lighter, 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. This is adjustable from both sides, to perfectly center the EVA pad over a high or low instep.
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. It can be adjusted while riding, with an innovative button which can be pushed to lift the buckle and facilitate the adjustment.
HIGH SECURITY VELCRO straps with integrated locking polymer teeth, that engage onto each other when the strap is closed that makes the closure more secure.
SIDI HEEL CUP Reinforced cup that stabilizes and supports the heel. Anatomically shaped, reduces heel slip and provides increased power transfer.
REPLACEABLE HEEL PAD For walkability, Sidi cycling shoes include a replaceable polyurethane heel pad.

SIDI size measurement procedure.
Measure your foot by following these steps to obtain the reference measurement.
1. Put a piece of paper on the floor and mark the following points.
2. Mark the point in front of the tip of your longest toe and then mark the heel point for both left and right
3. Measure the distance between the heel mark and the toe mark. Record the cm/mm measurement and compare to the size guide chart for the suggested size. Use the size of the larger foot, most people will have slight difference between the left and right foot.
