Microtech Microfiber incorporates features of resistance, stability, lightness, transpirability, water-repellency and eco-friendliness. It is manufactured using the "Water-Tech” water treatment:
- Lower environmental impact
- Less noxious emissions into the air and into the work environment
- Water-based products, not solvents, were used, which is beneficial to the environment as well as the final user.

The Soft Instep 4 Closure System is a wide, anatomically curved strap combined with a soft, thermo-formed EVA pad that distributes pressure evenly over the instep area. The Soft Instep Closure System is adjustable from both sides, to perfectly center the EVA pad over a high or low instep. The system eliminates the need for the High Instep Extender. The Soft Instep Closure System is replaceable.

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 Techno-3 Buckle is serviceable and replaceable.
