Boots of star striding

Boots of star striding  were a type of magical pair of boots that allowed its wearer to walk across gravity planes, outside of spelljamming ships in wildspace.

Powers
In addition to allowing travel across gravity planes, albeit at half speed, these boots continually oriented their wearer to, and between, these planes. The wearer could leap between, fall, or otherwise maneuver between the planes, or the surface of spelljammers, with no oscillation.

Like most magical footwear, boots of star striding shrunk or grew to snugly fit the foot of its wearer.
