I bought 2 pairs for my daughter and myself.  We were traveling to Canada, and would be staying on Georgian Bay.  The water was crystal clear, and I knew ahead of time that the bottom was all rocks.  I knew we would need something to protect our feet.  The price was cheap, and we would only be using them for a week.<br />After 2 days of use, my daughters soles came unglued.  After 4 days of use, mine had holes where my toes touched the fabric.  The tread was not good for rock climbing through the water.  Although the larger rocks had algae on them, so we would slide off of those.  They served a purpose for a week.  We swam with them, and walked around the outside of the house with them.<br />These are probably meant more for indoor water activities, or work around the outside of the house.<br />They were comfortable, fit well.  They are now in the garbage.  They served their purpose for a week.
