No they prefer fix rubber or aluminum as the nylon stud frequently breaks down and can cause lacerations or embed in players
Soccer boots are lower cut and and 6 studs - rugby boots are cut slightly high at the ankle and can have 8 studs
Rugby boots need studs in order to offer the player grip on grass and mud, which can be slippy.
The reason why moulded boots or blades are not allowed in rugby is because they could potentially cause harm to other players and the person who is wearing the boots. Moulded boots don't have the same amount of turn as a normal rugby boot and can cause injuries such as broken ankles and muscle strains which i have experienced myself. Also steel blades could be sharpened not maliciously but could cause cut, this is why referees check studs before kick off. I hope this helps Jack
to gain grip in grass and muddy conditions
there where metal studs in the future but as i know today they are not exits.
Yes, six studs are allowed in soccer games but they are best to use when playing on soft ground. The only situation that six studs may not be allowed, would be if you were playing on AstroTurf. Some shoes can be damaging to AstroTurf.
Cleats are normally plastic and moulded to the boot sole there are normally 6 to 8 depending on the make of the boot. The normal rugby boot will have aluminium studs which screw in for replacement and these boots carry 6 to 10 studs
