Aerodynamic Design for a Wattage Gain
Aerodynamics are crucial, especially when you can’t draft on the other riders and have to overcome drag by yourself. With the Aero, we opted for a simple singular dial-lock to fasten the shoe. The lock is protected by a smooth lace cover, without texture or dimples, which opens with a zipper. Those choices are more about aerodynamics than merely aesthetics. As a result, due to the smooth finish, a wattage gain to overcome aerodynamic drag can be observed, as proven during our series of wind tunnel tests.
Comfortable for Long Distances
The carbon sole gives efficient power transfer while enhancing breathability and comfort. This thoughtful design allows for a more accommodating fit, catering to both narrow and wide feet. The result is unparalleled comfort across long distances, ensuring that athletes enjoy the perfect blend of performance and fit.
Superior Ventilation
With added ventilation, the Chronos 4E is specifically designed to keep your feet cool under the heat of competition. Its enhanced airflow makes it exceptionally suited for hot racing conditions, helping you maintain peak performance when temperatures rise.
A Stiff Carbon Shell Saving You Energy for the Run
The Chronos 4E is equipped with a high-end carbon sole that combines stiffness with a flatter profile, optimizing efficient power transfer. So you still have energy to spare for your final stretch.
