To put it simply, the answer is yes. However, this will all depend on the type of steel tip dart that you bought. If you purchased an especially heavy dart, such as a 50g model, then you wouldn’t want to switch over to plastic tips, as this is just too heavy. If the darts that you want to switch over is a bit lighter, in the 20g range, then you would be ok to switch to soft tips. You would also only be able to switch over to soft tips from steel tips if you purchased darts with removable points. If not, then it would be impossible to remove the old, steel tips and put on new soft ones.
