The Wise Decision
The shoe that combines the best for everyone: whether racing or a casual ride, the Sidi Genius 10 Mega is simply the best platform for a great day in the saddle. Built on over 60 years of experience in manufacturing cycling shoes, Genius is designed on a carbon composite sole that offers the perfect combination of strength and comfort, while the Microtech upper adapts to the shape of the foot for superior comfort.
The Sidi Carbon Composite 20 Sole is constructed of Carbon Fiber injected into a nylon matrix. The Nylon is impervious to water damage and doesn't lose rigidity in hot or humid weather or as it ages.
Soft Instep Closure & Tecno-3 Systems
The closure system features an ergonomic instep strap, anatomically designed to fit securely, while still comfortable. It can be easily adjusted on either side to provide a perfect fit, accommodating even those with a higher instep. Additionally, it can be replaced whenever necessary.
SIDI's Tecno-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. The closure uses a new proprietary SIDI Wire monofilament 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 newly designed integrated heel cup is light weight and reinforced to avoid deformations after prolonged strenuous use.
