Just because it's non-Newtonian doesn't mean it's identical to oobleck. All it means is that it's not Newtonian.
Besides, you can run on water (or at least, some lizards can) at high enough speeds, though I'm not sure if water still behaves Newtonian in those situations.

For a human-sized object running on water, it's more about inertia - viscosity doesn't really come into it at that speed and scale. In other words, the Reynolds number is high in that situation.
