I think the best way to start is in wedges...4-5 in. max. They're a good start b/c you can get the feel of height without the fear of falling. They also give you a good idea of where you need to focus your balance center. Keep your shoulders back and your head "high" and try to put one foot in front of the next. This might sound silly, but try practicing with a shoulder bag or hobo purse. It's a distractor and it gives you some natural pull (sway). Good luck!
