I am a sailing coach and bought these as an alternative to flip flops on a boat. They are of good quality and have lasted 2 seasons so far. Grip on the fiberglass skiffs is decent and feet don't get hot in warm weather. Drain well and stay tied. The only thing I complain about is that they are a bit pointed at the widest part of the foot and are in no way inferior to mesh or leather. I have a wide foot so it won't be a problem for others.
