how powerful would "super jump shoes" have to be?

I was just wondering, if there were "super jump shoes", that would hit on the ground and would propell you upwards, how powerful would those shoes have to be?

I was hoping that you could use poweful magnets to do it. If you put like ends of two magnets together, lock them in place, and when you would be ready to jump unlock them so they would repel, how powerful would the magnets have to be?

The force needed depends on how high you want to go when you're propelled upwards.
