1. Prevent the soles of the feet from sliding in the shoes. The bed in the shoe is flat, but your sole is not. Therefore, when walking, the soles of the feet will slide in the shoes, so every step should be more energetic, and long-distance walking is more likely to increase all kinds of injuries. The use of three-dimensional insoles can fill the gap between the sole and the shoe bed and reduce the sliding of the sole in the shoe.
2. Improve support and improve the stability of the pace. Insole with heel support cup can reduce the swing when walking, thus reducing fatigue and reducing the chance of trauma.
3. There are two kinds of shock-absorbing insoles. One is to use a hard cup-shaped heel support, because people's heel muscles are thicker, which is a natural shock absorption function. As long as it is supported by hard rubber with appropriate curvature, it can play a good role in damping vibration and is suitable for some activities with stable and lasting pace, such as fencing, walking and hiking. The other is to assist other soft materials, such as gel and air cushion, to absorb the impact when the foot touches the ground, which is suitable for running, basketball and other high jump sports.
Correcting the posture of walking and standing sounds amazing, but this is exactly what orthopedic insoles can do. Many people are born with other factors, such as the spine and leg bones are not 100% vertical when standing, or swaying from side to side when walking, which will cause various bone and joint injuries for a long time. Orthopedic insoles can correct the posture when walking and standing, thus reducing trauma.
5. Insoles can also absorb sweat and sweat, because the feet will discharge sweat and hot air when walking constantly, so that the loose tissues of insoles will be absorbed and excluded from the shoes to keep the shoes clean. Insoles can also deodorize.
