I wanted some cheap water shoes to do a tubing trip down a river.  These sufficed, and I would buy them again, but they aren't for a person who plans to walk around a lot in them or if you have small feet.  I bought the smallest size (5) thinking that since I'm a size 5 in some women's shoes these would work, but they were too big and at times I felt weighted me down because they filled with water.  The cord helps keep them on your feet though, so overall they worked for what I needed.
