During the act of running, there are points in time when both feet are in the air at the same time, creating a situation where the feet alternately leap and land. A heavy load is exerted on the leg during running, particularly on the foot. Insoles in running shoes help in absorbing shocks and decreasing the load on the joints, and personal customization will improve support of the runner’s foot.
Custom-designed insoles designed for sprinters are very light and provide better stability to the front portion of the foot during running. The use of insoles contributes to the prevention of stress fractures and considerably decreases the pain suffered from shin splints.
The use of insoles assists in the following areas:
• Prevention of stress fractures
• Better stability during running
• Suitability to forefoot running
• Suitability to spiked shoes
• Reduction in pain from shin splints
