  I was thinking some sort of gravity nullification system that evaluates the amount of force the wearer (of the boots) exerts when jumping. It would take training to learn how to use them-no civilian could pick them up and go. I would put the jumping power somewhere around 30ft straight up (give or take a few feet) and as much as 45-60 feet with a running jump horizontally. 
   If the wearer was just trying to move around a null gravity environment the boots could be calibrated to simulate gravity. The boots are extremely high tech-one of the first things the space industry began working on. 

Does that make sense?

Yes it does. Thank you.
