I had trouble finding a "water shoe" for my son's marine science camp that he could put on himself AND that was comfortable and that would be protective in the marshes.
He has in recent years no longer liked his Keens.
We tried many water shoes and these are by far the best!  The zipper style makes it easier for him to do himself than the pair with the bungee cord. I have also washed them in the washing machine and they dry fast.
