How organism like 'pond skaters' can 'walk' on water?

The surface tension of the water is enough to support them because they don't weigh much and their weight is distributed over a relatively large area - spreading bristles on their feet.

If the question that you are asking is "How can the insect known as a pond skater appear to walk on water?" then the answer is simple. Surface area vs surface tension and the minimal displacement of water. Water in it's stagnant state retains a surface tension, much the same as if you fill a glass of water to very top and then a little more water is still visible above the glass. This is a result of surface tension. The pond skater uses this to its advantage as it "skates" across the surface of the water. Displacing its weight by evenly distributing it over six legs and a larger than itself "surface area".

Their feet structures distribute their body weight over the water just enough to not break the water's surface tension.

They are so light weight and have such small feet that they don't break through the surface tension of the water.

those bugs distribute their weight purely the appropriate way, so as that the floor tension of water is powerful sufficient to hold them in that place. observe how they constantly "walk" with their legs outspread in each and every direction.

even distribution of their weight when they get on the water
