I like the feeling of walking on the beach, half sinking into the sand with every step.  I have been looking for a pair of shoes that will allow me to enjoy the walk without having to pay much attention to avoid sharp debris (when barefooted), or have to make frequent stops to empty out the sand cumulated inside the regular walking shoes.  I found it in these mesh slip on water shoes. I tried it out today, even dug deeper into the sand on purpose and  watch the sand flow back out when I took the next step.  I noticed a small amount still cumulated inside the shoe after my walk, but it did not give me any discomfort during the walk.  One clarification though - I only walked on the dry sandy part of the beach (my preference).
