I've heard u can pay huge sums of money to go into space... be
in a no gravity environment and you'll grow taller.
And i have also heard that you can break your legs, and let
carthilage healh and rebuild or somethinglike that, and you'll get
increases in height. But my advice is this: wear your normal shoes,
buy a new pair that will fit your feet while your wearing
yournormal shoes, and wear all the sets of shoes for height. It
makes u look taller without looking like your wearing
platforms.
