What is the greatest benefit of orthotics?

Yes, it'll be beneficial to all regardless of having foot or lower leg alignment issues or not. Scientific research shows that orthotics help redistribute the pressure through the foot, allowing areas of higher pressure to find relief and thus reducing foot pain when walking or running over long periods. Orthotics have been shown to reduce lower leg pain, improve overall posture and reduce injury in athletes. Athletic performance can be gained using orthotics by improving balance through the redistribution of the weight through the entire foot, providing a stable and cushioned surface to land on while running. Athletic performance is also gained through the improvement of balance and support through the foot, allowing for better motion control and reduction of fatigue in the lower limbs. The greatest benefit, however, is the injury prevention benefits of orthotics, especially in athletes with sustained repetitive movements, such as road runners. Results have shown to reduce plantar fasciitis and heel pain with the introduction of orthotics.
