The function and characteristics of the first and third types of running shoes
Running shoes can be divided into three categories: providing shock absorption, providing stability, and providing motion control.
Running shoes that provide shock absorption, usually with a softer midsole, help the foot to be evenly stressed during exercise and help the foot absorb shock. The shoe body is usually lighter, and the stability will be relatively poor.
A running shoe that provides stability, the sole usually has a column with uniform force or a sandwich structure on the inside. These special designs can prevent injuries caused by over-pronation of the foot, and provide good support and durability for the inner edge of the foot.
Shoes that provide motion control, usually stiffer, reduce or control excessive pronation of the foot and prevent ankle injuries, and are usually heavier than other running shoes. The structure is generally such that the inner layer is a column with uniform force to control the pronation of the foot, and the midsole provides durability; the outer layer of rubber is more wear-resistant.
Second, running shoes How to choose
The choice of running shoes, which type of running shoes is suitable for you, requires you to make a conclusion after understanding your foot shape and gait type.
The human foot usually has a normally curved arch structure, which we call the ‘arch of the foot’. When doing the wet footprint test, the left footprint will be missing a piece in the middle. According to the size of the missing part, the human foot can be divided into normal foot, flat foot and arch foot.
Wet Footprints: Step on a piece of white paper with your right foot dipped in water or ink. Find the widest point on both sides of the footprint and draw two parallel lines vertically. Find the point on the arc of the missing part in the middle of the footprint that is closest to the vertical line on the right, and draw a vertical line past this point. Area A is on the left and area B is on the right. The foot type is determined according to the ratio of A and B areas.
Normal foot type: The ratio of A and B area is close to 2:1.
Features: In the process of exercising, this type of foot usually touches the ground with the outside of the foot, and the ankle is slightly bent inward, which can effectively absorb vibration.
Best running shoes: Running shoes that provide some stability.
Reminder: Generally speaking, a pair of feet with a normal biomechanical arch is not necessary to wear shoes that improve motor control.
Flat feet: The ratio of A and B areas should be less than or equal to 1:1. Area A is smaller than the footprint of a normal foot size.
Characteristics: The arch of the foot is very low, and the footprint looks like the entire sole of the foot. When running, the foot typically lands on the outside and the ankle exhibits excessive outward flexion. Over time, different degrees of fatigue damage will occur.
Best running shoes: Shoes that control arch drop, firm soles that provide motion control, or high stability.

Flat feet: The ratio of A and B areas should be less than or equal to 1:1. Area A is smaller than the footprint of a normal foot size.

Best running shoes: Shoes that control arch drop, firm soles that provide motion control, or high stability.
Reminder: Avoid running shoes with good shock absorption, as they will be relatively less stable.
Arch foot: The ratio of A and B area should be greater than 2:1. Area A is larger than the footprint of a normal foot.
Characteristics: Footprints exhibit narrow imprints. In severe cases, there is no B area. This type of foot is usually in a state of external rotation and has good flexibility, but the arch itself cannot provide sufficient shock absorption.
Best running shoes: Running shoes with shock absorbers provide plenty of flexibility to protect your feet from vibrations.
Reminder: Running shoes with good shock absorption effect will be relatively less flexible.
Gait: When running, the outside of the ball of the foot contacts the ground first. For people with the same foot type, the wear parts of the soles may be different. This is because the running posture of each person is different. The normal landing of the foot during exercise should be the heel first, and then the center of gravity falls on the entire sole of the foot, and then Make a smooth transition to five toes while applying pressure and pedaling.
Severe pronation: When running, the toes will drive the ankle to rotate inward, the sole of the foot is severely valgus after landing, and the center of gravity falls on the inner side of the foot. The feet and ankles do not provide good stability to the body, and shocks from the ground cannot be absorbed effectively.
The best running shoe: Good stability and motion control.
Normal gait: At the end of a gait cycle, the toes rotate the ankle slightly outward. The feet and ankles can be kept in line with the calf. After landing, the center of gravity will fall on the entire sole of the foot. This means that the foot and ankle can effectively absorb shocks from the ground, supporting and stabilizing the body. Get ready for a toe kick.
The best running shoes: running shoes with good shock absorption.
External Rotation: When running, the toes rotate the ankles outward. After the foot hits the ground, the center of gravity falls on the outside of the foot. But throughout the gait cycle, the soles of the feet do not turn inward. Since the outside of the foot is continuously stressed after landing, this will cause the little toe to bear most of the pressure during the kick-off process.
The most suitable running shoes: running shoes with strong softness and shock absorption, especially running shoes with a breathable interlayer of moderate density on the sole.
