An AG sole is designed for artificial grass, but the actual surface and pitch rules remain decisive. Here is how to compare models and check their fit.
AG, FG/AG or TF: understanding the intended use
| Sole | Use to consider | Essential check |
|---|---|---|
| AG | Long-pile artificial grass | Explicit compatibility and stud layout |
| FG/AG or MG | Several surfaces specified by the manufacturer | Instructions for the exact model |
| TF | Short, firm artificial turf | Permission from the operator and actual grip |

Choosing a pair for your usual pitch
Identify the surface before choosing a brand
Ask your club about the surface and which soles are allowed. A marketing label such as “4G” is not enough to determine the right footwear. Local rules can differ, even between two artificial pitches. Photograph the label on your current pair and the sole: this avoids ordering an FG version with the same name as the AG version you want.
Compare more than hollow studs
AG configurations vary. Short studs, often rounded, are common; they are not all conical or hollow. Examine the whole sole, forefoot flex and internal width. An explicit technical designation is more useful than a vague promise of “all-terrain” footwear.
Try on both boots with your match socks. Walk, bend your knees and check your heel: it should not slip out of the boot. Your toes should be neither squeezed nor curled up. For children, check the size regularly without buying an excessively long pair to allow for growth.

Grip and cruciate ligaments: avoiding promises
A mechanical study of six shoes on natural grass shows that rotational traction depends on factors including the model and the surface. It does not show that an AG sole or hollow studs prevent an anterior cruciate ligament rupture. Choosing footwear is part of preparation, alongside warming up and an appropriate return after injury. Persistent pain warrants professional advice.

Budget and care
Compare the delivered cost, the return conditions after trying the boots on and the exact sole specification. Remove infill granules after use, leave the boots to air-dry and watch for separation between materials. A discount does not make up for an incompatible surface. For other uses, see the FG and TF guides.
Frequently asked questions
Do AG boots prevent cruciate ligament injuries?
No sole guarantees this protection. Footwear and surface compatibility matters, but a claim of prevention based solely on hollow studs would be excessive.
Is an FG/AG boot suitable for every artificial pitch?
Check the surfaces specified for the exact model and the pitch rules. The dual label is not universal permission.
Do AG and TF refer to the same sole?
No. AG is intended for artificial grass according to the model's specifications; TF uses small rubber nubs for shorter, firmer surfaces.
