Ah, I have seen conflicting stuff about that. Yes, certainly helpful with balance and body positioning. My wife learnt to ice skate alongside someone who'd roller skated (not on roller blades, before those came out, really). I'd think roller blades are a bit closer to ice skate blades in that they run vertically and centrally underfoot.
