Some advice that I learned from my dad on these things, he did a ton of research before buying a pair of these:
First off, I hope you got the high-quality ones. Anything under 300 USD will probably break in a year or two (If you use them strenuously)
Second, make sure everything is perfectly symmetrical on the stilts. My dad measured his, found out one was off by a centimeter or two, called the makers, who immediately told him to send it back to be fixed, as that was WAY too off center. It doesn't feel like much, but it makes you walk awkwardly, and eventually kills the tissue in your knees.
Third: Don't make any mods to the size of these things (that would cause any sort of change in the curve in the back). This will not only probably void the warranty, but make them extremely prone to breakage.
And lastly, not advice, but just some experience. I was once running with them down the road, tripped, and fell onto the concrete. It didn't hurt that bad. I'm not saying try to push the limit, but don't be afraid of a close encounter with the ground.
