The SIDI Genius has gone through many changes during its tenure as a mainstay in the SIDI range. The newest version, the SIDI Genius 10 has a new sole and closure system compared to previous versions. It has all the hallmarks of a classic Sidi shoe with its clean looking, perforated upper, iconic heel cup and the longstanding Tecno-3 retention dials. The upper material is made from durable, eco-friendly materials. The SIDI Genius 10; good comfortable fit, provides performance and durability.

TECHNOLOGY:
SOFT INSTEP CLOSURE SYSTEM - 4:  a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The system is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. 
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. 
SIDI Heel Cup: The reinforced heel keeps the foot in a optimal position and avoids the shoe being deformed by extreme performance or prolonged pressure. 
CARBON COMPOSITE 20 SOLE: The carbon/nylon composite sole provides technical features resulting in a comfortable, durable, light and stiff sole. The central part of the sole is marked with a scale, to facilitate the correct fixing and alignment of the cleats. Equipped with the SIDI 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.
