A chain is only as strong as its weakest link. Energy has to be delivered from the legs, core, and upper body down through the foot and ankle to the pedal. If the foot is unstable, there is a large “mush” factor that creates inefficient power transfer to the pedal and a significant “energy leak.”
To ride long and fast, you need to deliver as much force as you can efficiently and effectively from the body to the pedal to turn the rear wheel. To do this, your body must work together with the bike to deliver power to the pedals with as few “energy leaks” as possible.
The contact point between the delivery of the body’s force to the bike is at the pedal/shoe interface. Energy can easily be lost at this link in the chain if force is being delivered through an unlocked, too-flexible foot. A fully supportive and corrective orthotic in the shoe translates into more rigidity and transfer of power. This equates to more watts per pedal stroke, less fatigue over time, reduced risk for injury and a more efficient rider.
Custom orthotics have been found to reduce pain, improve economy, postural stability, and improve pressure distribution. The use of full contact custom orthotics in your cycling shoes establishes foot stability, lower extremity alignment and efficient pedaling.
