The world’s largest bike maker is getting into the shoe business. Giant is introducing a new line of performance footwear, featuring what it calls Motion Efficiency System. The new road and off-road shoes are claimed to deliver improved power transfer, comfort and fit. All of the new models were developed under Giant’s Dynamic Cycling Fit design philosophy, which aims to create gear that functions best while in motion.
Three new models — the Surge road shoe, and the Charge and Amp off-road shoes — were conceived via a collaborative process that included biomechanics experts, the Rabobank Development Team, and Giant off-road racers. Testing was conducted at various laboratory settings, team camps and races around the world.
“Giant came to us with its Dynamic Cycling Fit concept and challenged us to explore new ways to create a more seamless connection between the rider and the bike,” said Simon Luthi Ph.D., an Oregon-based biomechanics expert in the field of athletic footwear. “Together with Giant and its pro athletes, we engineered, developed and refined this new Motion Efficiency System to optimize the natural motion of a rider’s foot.”

The Motion Efficiency System combines a stiff and efficient pedaling platform with just enough torsional flex to reduce pressure and strain in the lower leg. The result, claims Giant, is a more natural foot movement throughout the pedal stroke, which improves both comfort and efficiency. The system is built around several key technologies: the ExoBeam sole structure, the ExoWrap foot closure, and the ExoFlex toe section for off-road models.
The ExoBeam sole technology combines stiffness in the forefoot, where most of a rider’s power is applied, with strategically engineered flex zones to reduce tension and strain in the lower leg. With the “beam” replacing the traditional plate sole structure used in most high-performance cycling shoes, a rider’s foot can be fully wrapped in the enclosure system.
The ExoWrap works in harmony with the ExoBeam to form a 360-degree foot enclosure that creates customizable fit and comfort for all foot shapes. While most enclosures simply pull the foot down toward the sole, ExoWrap supports the foot by also pulling up.
Off-road models including the Charge and Amp also feature ExoFlex, which allows the toe area of the shoe to move independently of the ExoBeam carbon sole. This results in better traction when running or walking up steep climbs. Ideal for cyclocross or trail riding, ExoFlex also reduces heel slip.
The new footwear models will be available later this year. For more info visit www.giant-bicycles.com and learn more about the development of the new technologies in this video.
