The Sidi ERGO 5 Road Cycling Shoe has a SIDI classic design with many upgrades so that a racer has an advantage on the race course. Sidi’s Tecno 3 buckle system allows a rider to customize the fit through the use of two different ratcheting dials that fit along the entire length of the shoe. Sidi’s new Wire material is used to tighten the shoe so each part of the shoe fits around your foot with equal pressure. The buckle system is also a quick and easy fitting system that can be adjusted while on your bike. The lower portion of the cycling shoe can be tightened using a Velcro strap made with integrated polymer teeth that latch onto each other and become unmovable when you are pedaling. For further comfort and security, the Soft Instep Closure System is a soft, wide curved padded strap that can be adjusted from both sides to distribute pressure evenly over the instep. Around the heel, the reinforced heel cup keeps the foot comfortably in place as you pedal your bike. The cup has been made lighter while not losing any of the security it provides to the rider who is required to sprint and attack out of the saddle. The tongue has more ventilation so a rider’s foot stays dry and the Tecnopro synthetic leather doesn’t absorb moisture so the material maintains its shape. The leather has enough flexibility to fit around your foot, yet it’s strong enough to keep all your foot power inside of the shoe. Sidi engineers found a way to put two different materials together, nylon and carbon fiber, to create the Twelve Carbon Composite sole that is lighter and stiffer than any previous sole. Since the nylon doesn’t absorb water and doesn’t lose rigidity in hot or humid weather, the sole maintains its race stiffness. The Ergo 5 is designed for the racer who wants speed and security in his cycling shoes.
