Modern life involves much walking on hard surfaces, pavements, reinforced concrete floors, steel decking, and it is worth pondering whether shoes provide adequate cushioning. In modern shoes, your heel hits the pavement first, before the rest of your foot. With the pace of modern life hit is the right word, and the cushioning provided by the heel of your shoe as you pound the pavement is at issue.

I think that the cushioning is inadequate and cannot be improved because the basic concept is faulty. One is better off spending a few months learning to walk barefoot.

Wait a minute. There is no cushioning at all under the heel when you walk barefoot; how can that be an improvement? It is time to get technical and explain the difference between a soft material approach to cushioning and a mechanical approach.
