Pain with DDR

[PureBlue]

Sometimes my legs will get really stiff if I play DDR for about half an hour to an hour straight, but other than that I don't usually get any sort of pain while playing DDR.

Except for one time when I was playing in a pair of Converse Chuckie T's (very lightweight and not much support) and I tried playing Maxx Unlimited on Heavy. I twisted my ankle after tripping on a bracket during the jumps at beginning. I couldn't walk straight for about 2 days, it was painful .
