WOODSAIR EFELSTAR Champ Insole for Tennis professionals features 300 high-elasticity air cells built into the entire base and a functional system that complements them, improving the safety by maintaining a steady balance when running. The high functional EFELSTAR Champ Insole for running absorbs the impact of the exercise’s load and generates rebound elasticity to reduce energy consumption and help prevent injury.

We should always be careful regarding injuries of the knee meniscus and ankle joints that serve as a cushion when landing. The EFELSTAR Champ Insole for Tennis is designed to prevent the center of gravity from being too much on one side when landing. The air cell system built into the insole quickly maintains the landing balance, helping to prevent ankle injuries. The EFELSTAR Champ Insole for runners is designed to absorb 6-8 times as much weight as one’s own weight directly from the sole at the moment of landing. Runners suffer from heavy pressure loads on their legs, knees, and feet as well as fatigue stress due to impact. The Champ Insole for runners only has a multi-layered structure of shock absorption to reduce the pressure load and fatigue stress on the lower body, preventing injuries. An excellent restoration function to its original state with a good rebound elasticity after shock absorption, is a feature of the EFELSTAR Champ Insole for runners.
