I believe it works. Due to the polar bonding of water molecules, water molecules attract each other. This is why if you bring two drops of water near each other they will immediately combine. This creates a skin on top of the water called Surface Tension. Many bugs and insects use this to climb across water. If a human was able to skim in such a manner that surface tension would support them for a short amount of time, one might be able to take two or three steps before falling. However, since they would slow down drastically during the run, time with foot on water would be increased, not to mention the water would be disturbed from the other steps.
