This was a DAW paperback I read in the late 70s or early 80s.
Details are sketchy but here’s what I remember.
It takes place in the far future. Humans are more or less immortal and have stopped having children. All except our hero’s parents, thinking they would start a cool fad the have a child (boy) And when everyone reacts with horror they are forced to keep the kid hid and deny his existence as much as possible.
As he grows older he bugs his parents for a pair of wings (large artifical strap on wings with an anti-grav unit that enable humans to fly). Somehow he hooks up with a young woman and they revive a group of scientists from suspended animation.
Like I said, details are sketchy but if any of this rings a bell let me know. Thanks!
