Understand the foot type smart running shoes

When you plan to start running, it is important to understand your feet and buy a pair of running shoes that fit your foot. Only in this way can your exercise go smoothly and achieve results while avoiding injuries. Picking running shoes is not very complicated. Just follow the steps below.

First, the structure of running shoes

Manufacturers of sports shoes have conducted the study of sports biomechanics for most people's feet and produced corresponding shoes according to different foot features to meet different people's needs. Running shoes can be divided into five types according to their functions (control actions, cushioning, cushions, stability, competition, cross-country), shoe type can be divided into straight, semi-bending, bending three kinds.

No matter what the brand's main structure, the running shoes with better quality have similarities. The outsole is a layer that touches the ground. The texture is slightly hard, wear-resistant, and non-slip. There are also a few extremely light running shoes with no outsole, and these shoes are only suitable for running on a treadmill. The midsole is the most important shock-absorbing layer. It is softer than the outsole, and the support at the arch can control the twisting force of the shoe's bending and transmit the impact force from the heel to the sole of the foot. The damping device in the heel is the most important, and each brand has its own technology and characteristics. The insole can usually be removed. It is the last line of defense for shock absorption and correction of foot defects. The upper is mainly to make the feet and shoes tightly combined with the function of air cooling. The hard heels of the heel can increase the stability of the foot when it lands.

Second, the function of sports shoes

According to different features, sports shoes can be divided into the following five kinds:

1. Control Actions: Suitable for moderate-to-severe varus feet, as well as people with higher weights, it can increase the runner's control of the heel and running movements, and can support the arch area. Its external feature is the thickening of the arch, and the weight of the shoe is moderate.

2, cushioning cushion type: suitable for running technology is better, with the foot of the palm or the tribal land, with the soles of the feet and the lateral support runners. The weight of the shoes is medium and the soles are thick.

3, stability class: suitable for mild to moderate varus foot type, with runners supporting the middle and outer side of the foot. The shoes are of medium weight.

4. Competitions: Suitable for runners with good running skills, lighter weight or slightly inverted feet. Shoes are lighter in weight.

5, off-road categories: thicker shoes, deep groove, suitable for running on the ground, such as running on the natural ground. The weight of the shoes is heavier.

Third, analyze your foot

After understanding the structure and function of shoes, you should study your own feet. "Wet foot test" can help us determine the foot shape. The “wet foot test” is to apply water to the soles of the feet and step on the dry ground. Then, the foot is classified into the following three types according to the shape of the footprints. Of course, there are many people whose feet may be between the two types, then it depends on which one is more obvious.

1, normal type

The height of the arch is normal and there is a large curvature in the middle of the footprint but it is not interrupted. When running, it usually hits the ground on the outside of the heel, and then rolls inwards to reduce the impact force. Finally, it moves to the full ground. Such runners with normal foot and normal weight are highly efficient in terms of sports mechanics, and they can choose semi-bend stable or cushioned running shoes.

2, flat foot type

Due to the lower arch, the footprints are full and the entire foot prints on the ground. Flat-footed people tend to land on the outside of the heel while running, and then roll too far to the inside to form an inversion. Many unacceptable joint injuries can occur if left uncorrected. Flat runners should choose straight or semi-bend shoes with special reinforced arch pads to reduce the degree of varus. Avoid wearing cushions that are too thick, or curved running shoes.

3, high arch type

The outside of the footprint is very narrow and almost interrupted, and the arch has a large internal space. This kind of foot usually does not roll enough to buffer when landing, so the absorption of impact force is not obvious. This type of foot should choose shock absorbing cushions, curved or semi-bent shoes. The flexibility of the sole should better increase the range of motion of the foot, avoiding stable shoes.

In addition, no matter which type and brand of running shoes you choose, try half-size (English and American shoes) to a shoe size (European shoes) when you try on, because the feet will swell during exercise. There must be enough room for this.
