The ease with which they are put on and tightened, then loosened for removing,, is a real plus.
They seem durable and once I'm in the water and working out I barely feel them.
For the first little while though, they are just loose enough around the edges that there is a rubbing sensation which is annoying; it does not, however, result in any irritation to parts of the foot and after a few minutes, they are quite comfortable.
