|: What's the difference to conventional mounting?
The plates are mounted farther forward than regular artistic or "disco" type skates. The rear axles are mounted more or less in line with the ankle bone, not in the rear half of the heel like regular skates. A longer wheelbase is used so that the front axles are as close to the toes of the boot as possible, instead of crossing at the ball of one's foot. They're no good for roller disco moves (although you can shuffle just fine with them) but they handle more like an ice hockey skate. The centre of balance is now in the arch of your foot, instead of being more to the rear like roller rink skates. I'll see if I can put together a comparison photo to show the differences better.
