Ugh, I know what you are talking about.
That whole low gravity thing in TES series is killing me.
Same is when you are running down the hill.
Make a faster movement and before you know it, you'll end up as Skywalker wannabe and realize that you are not one by having your legs broken upon falling down.
I mean, it's true that it's not that realistic to run down the hill since you will probably end up with you neck between you knees by the time you reach bottom, but low gravity thing is not the answer that's for sure.
I don't think there's any fixing to be done. If you run full stride down a flight of stairs, you will miss most of them and end up a crumpled heap at the bottom. The answer for me has been to walk.
The thing is that you skip few stairs, not start levitating above them.
I used to run down the stairs a lot and my legs are still fine.
At least better acrobats should be able to run down 10-15 or so stairs and be fine or something like that.
Ugl, I also remember times when you run down the stairs in some dungeon and then low gravity kicks in.
You end up running in the sealing or something like that.
Really annoying in my opinion.
Down have anything about your character being clumsy and breaking few bones if he runs down the stairs, but that whole low gravity thing should be fixed in my opinion.
