According to the needs of biomechanics, running shoes can be divided into three categories: providing shock absorption, providing stability, and providing motion control. Provides shock-absorbing running shoes, usually with a softer layered sole that assists the foot to evenly apply force during exercise to help the foot absorb shock. The shoe body is usually lighter and the stability is relatively poor. For running shoes that provide stability, the sole usually has a column with a uniform force or a sandwich structure on the inside.
These special designs prevent damage caused by excessive valgus of the foot and provide good support and durability for the medial edge of the foot. Running shoes that provide motion control are usually hard, which can reduce or control excessive varus of the foot and prevent ankle injury. This running shoe is usually heavier than other running shoes. The structure is generally that the inner layer is a column with uniform force to control the internal rotation of the foot, and the laminated sole provides durability; the rubber of the outer layer is more wear-resistant.
The flexibility of running shoes with good suspension effect will be relatively weak. When running, the outside of the sole will be in contact with the ground first. For the same foot type, the wear parts of the sole may be different. This is because each person's running posture is different. The normal landing during the exercise should be the heel first landing, then the center of gravity falls on the entire foot, then Smooth transition to five toes while being stressed and slamming. Which type of running shoes is right for you, this requires you to understand your foot type and gait type before you can draw conclusions.
