I spent some time looking for a good pair of water shoes.  I trolled in Target etc and each pair I bought were less than expected and very cheaply made.  Then I found these.  I wear these shoes everywhere.  They are comfortable and I feel I have enough support to wear them on a regular basis.  I, like others, got a blister on my hill the first time I wore them.  This only happened on my right heel and a close look showed that there is a small fabric seam that goes along the upper back of the shoe.  I stopped at a local drug store and picked up some mole skin, which is adhesive on the back, put a small piece up the back seam of the shoe and have had not such problems since.  If it were not for the seam problem this would be a 5 star review. I will definitely be buying more Jambu shoes.  So glad I found these.
