From personal experience, yes. But with a caveat.
First of all, you should stroke on blades the same way you stroke in figure skating. It east to develop a different stroking technique with blades that can spill over to figure skating. My coach made me awarre of that!! I was stroking like aspeed skater, rather than a figure skater.
The second point is to get inline skates that bend like figure skating boots. They now have such skates available and it has made a world of difference. I found that with regular inlines, my knees would hurt after a run. The reason was that the boot flexed differently than my figure skate boot does, resulting in the sore knees. With the new inlines, the knee pain is gone.
I try to get out 4 to 6 days a week and do 10 miles at a time. I found that it keeps my endurance up and my leg muscles in shape, especially in the summer when I don't have as much ice time.
Hope this helps.
