That's probably an old thinking. Everyone knows that a person with no feet will obviously not need shoes, so he sort of gets used to the notion that he does not need one. But in this fast moving world anyone with feet just needs something on his feet as long he has his feet and not when he does not have them or bother about someone who does not have them.
Its normal for anyone who is not content with what he/she has and want to strive for more, but as long as the path to get these things is right.
