If you can't stand in front of a breakable wall, glide into them to smash them open. If the wall is by the water, use the Freeze Blast to make a platform in front of them. If the wall is in the ceiling, it depends on the situation. For most of these there
is a path that leads above them, so keep looking for vents and such, or grappable points. In some situations (like in the collapsed streets area) you need to Glide Boost through them from beneath.
There is one in the destroyed city (or whatever it's called) with a riddler trophy above it. It took me a few minutes of thought, but I found that you can glide > Grapple > boost and fly right through it to break it. Other times, if they are on the ceiling,
that means there is another way above it.
