What are the meanings of "AG" and "HG" added at the end of football shoes? What is the difference?

divide sneakers into soles and uppers. Let's talk about soles first:

There are probably SG,FG,HG,TF,IC/IN, MG

AG soles for football shoes.

SG(SOFT

GROUND): That is what we usually call steel nails, which are generally detachable and suitable for wet natural grassland. The number of nails is small and long, generally 6. Basically, we amateurs have little chance to wear them. For the sake of others and our knees, we suggest not to wear them.

FG(FIRM

GROUND): the most common sole of high-end sneakers, which is suitable for hard natural grassland or very good quality artificial grass. The number of nails is more and shorter than SG's, but it is not recommended to wear it on artificial grass, especially if the ankle strength is not strong, it is easy to sprain your ankle. (I learned a lesson from blood ~~)

HG(HARD

GROUND): It is suitable for artificial grassland or soil field. The number of nails is one or two more than FG, and the nails are thicker and shorter. This is my favorite. Basically, they all wear the bottom of HG now. Like the big grassland in our school, it is just right to wear the bottom of HG, just enough to eat nails.

TF: That is to say, broken nails are usually used. This kind of nail has a wide range of uses, and it can be used in cement land or short human grass. For example, TF, the venue next to No.3 Teaching School in our school, is the most suitable.

IC/IN: flat-bottomed room.

AG/MG: the newly developed shoe studs suitable for China's artificial fields in the past two years have basically the same function as HG.

Choosing the right sole for the venue can be said to be the most important part of choosing sneakers, because even if your shoes are high-end and high-tech, it will be no use if the soles don't match the venue. If the spikes are too long and too few to eat in the grass, the stress area of the feet will be reduced, that is, the feet will be broken, and the pressure on the knees will increase, which will cause damage to the knees for a long time, which is very harmful; If the nails are too few and too short, they will slip, and there will be a feeling that they will not be able to start. Therefore, we must choose the spikes suitable for the venue, like our big football field Hg and TF, and some shoes' FG are barely acceptable. Small football fields belong to standard carpet grass, and only TF or double stars are more suitable.
