Rugby studs come in two types: replaceable and molded. Replaceable studs are usually made of metal and can be removed or swapped out. They are most commonly used on soft ground, where they offer better grip, traction, control, and speed on wet or muddy fields.
If you are using soft ground cleats it is highly recommended to buy back up studs as they can come loose over time and during play. Since there are usually on 8 - 10 studs on a boot (counting heel and forefoot) losing a stud can significantly alter the functionality of the boot.
WHAT TO CONSIDER WHEN PURCHASING REPLACEMENT STUDS:Â
Stud Thread Size:Â Rugby boot studs screw into threaded sockets in the sole of the boot. These threads must match exactly to avoid damage or loosening during play.
Stud Length: The ideal stud length depends on both the playing surface and the player's position. Longer studs provide better grip on soft ground and are typically preferred by forwards, while shorter studs are favored by backs who require greater agility and quick movement.Â
Generally we recommend purchasing studs that are around 11 to 19 mm long (21 mm is the maximum allowed by World Rugby regulations). The longer the studs, the better traction they afford on soft ground as they can penetrate the uneven or muddy ground much deeper making it less likely to simply slip on the muddiest upper layer of the field. Soft ground cleats also only have around 6 to 8 studs each shoe in order to efficiently distribute the weight on each stud digging in the grass.
Stud Material: While most replaceable studs are metal, you can actually purchase non-metal studs to work on firm or artificial surfaces where metal might not be appropriate or permitted. This prevents you from needing to own two pairs of boots for both firm ground and soft ground.
