Float ore and float stone

This float ore would be found at the bottom of the end islands. The ore would generate with void benith it and only on the outer end islands. It would drop an item called float stone. With these items you could craft boots that give you slight jump boost and slow falling for a short while when in air, similar to how the turtle helmet gives you water breathing for a shor while underwater. This ore could also work like nether gold ore where it would need to be crafted from nuggets to ingots before you could craft the boots.
