to gain grip in grass and muddy conditions
Rugby boots need studs in order to offer the player grip on grass and mud, which can be slippy.
Yes you can. However, Soccer studs are shorter beneath the sole of the boot than the regulation Rugby ones ( that is not an issue from a regulation perspective) and it does mean that grip is reduced. You would need to make sure that you have the type off boots that have screw in studs and replace them with the longer version - Normally the heel studs are the regulation length so you need to buy all heels studs. To check on stud regulation you can access the IRB site and search for boot regulations - there is a load of good info there to help you with rugby and the proceures and laws.
it can have 6 or more studs

Many players where soccer boots however, rugby "boots" have a higher ankle area to protect that area when rucking or be rucked over. The term "Rugby boot" actually refers to the earliest foot-ware which were in fact working boots. the studs were small studs which were used to reduce wear on the sole on the boot. These were worn by the players who came from industry especially heavy industry and coal mining.
some forwards prefer to where boots with 6 studs in the front sole and 4 in the heel whilst the majority (normally backs) will wear boots with a standard 4 studs in the front sole and 2 in the heel
No player would wear shin pads in rugby, there is no need for them.
Soccer boots are lower cut and and 6 studs - rugby boots are cut slightly high at the ankle and can have 8 studs
Yes. If you wear metal studs on an icy concrete surface, you will slip all over the place. If you wear rubber studs, they will grip easier. So therefore, rubber studs are better.
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
as long as they meet IRB regulations yes. You will need to check against the regulation on clothing and equipment section on the irb site.
Rugby boots are usually stronger and usually have 10 studs, where soccer cleats have around 16. Depending on which position a player plays in rugby, their boots may be as light as soccer cleats for backs, or heavier and sturdier for forwards.
