Running can be defined as controlled falling or fast walking but with the exception of a flight phase in gait (when both feet are off the ground for a moment in time).
There are some important ways that custom foot orthotics can help improve running performance:
Custom orthotics will help maintain alignment and comfort throughout the run and in-turn help with running form and technique. This will reduce the onset of fatigue and allow you to enjoy your runs.
If you are misaligned at the feet and ankles, such as in those who over-pronate, your feet and legs are not able to maximize efficiency with gait and stride. Custom orthotics can improve your alignment and function to maximize efficiency.
If you have comfortable feet you can focus your energy on running form and technique rather than on your feet getting sore or tired. Orthotics with different areas/types of cushioning can improve shock absorption and create even pressure in the feet. Proper weight distribution is key to improving overall comfort.
Those who have poor foot mechanics, such as those who over-pronate or under-pronate, might potentially experience an injury. Foot orthotics can help support poor foot mechanics. Seek advice to determine if foot orthotics would work to help prevent injury before it happens.
