Proper shoes, and listening to your body.
I did step aerobics for almost a year, and had no trouble. You DO have to watch your placement, and move at YOUR pace... not the instructor's pace. You have to remember the people who lead thse classes are fit, and do it constantly, and they're choosing where to go! I often stay a step or two behind so that I ensure my foot lands properly.
I have a weak ankle (leftover sprain from a few years ago) but never had trouble, because I was always careful, and wore non-slip shoes. Having the proper height on your step is important, too. Some of our less-able classmates would do theirs flat on the floor when they couldn't do all the steps.
Step aerobics is like any exercise. You have to use good form, be careful, and listen to your body!
