What should i look for in a good type of waterproof tape to align my 5th metatarsal and cuboid?

That won't work.: If the metatarsal and cuboid don't line up, as in a lisfranc fracture dislocation, the only way to line them up and hold them in place is with surgery. In order to apply enough pressure to the area with tape to reduce he joint, you would get skin break down beneath the tape so its just not a practical solution to this serious problem.

Not going to work: Tape is not strong enough to do this. See a foot doctor for a recommendation as I am not sure what you are trying to accomplish or what the actual diagnosis is.
