Stepping the innovation up from Sidi's famous Genius 7 model, the new Genius 10 dials in a flawless fit by adding dual Tecno 3 Boa closures.
The Genius 10 utilizes Sidi's 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. The fit 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 and what's more, it is fully replaceable should it wear out.
Sidi's Tecno 3 Boa system dials in fit along the entire length of the shoe, adapting the upper to the shape of the foot for a customized fit and feel.
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 Tecno 3 system is serviceable and replaceable.
The Genius 10's sole is an innovative blend of nylon and injected carbon fiber. The result is a featherlight and stiff sole optimized for efficient power transfer. The sole's midsection is millimetrically graduated to facilitate precise cleat position.
