I echo everyone's recommendation of drywall stilts. But I have 2 points to make.
Not everyone can use them. I've seen people who are snowboarders and skaters not have the balance to walk on stilts. So it's hit and miss.
But the best advice when using them is to take small steps. People get on them and begin a normal step which translates to a 6 foot stride and it doesn't work well. Small steps translate into a normal stride when you factor in the length of the stilts.
Dura-Stilts are really good. Your foot motions even transfer down, allowing you to stand on your toes. Any set of stilts with similar design should work well.
