Thing is, the only places available to use it are Hyrule Field, Lake Hylia, and Zoras River. Not much to interact with
Nah. Works in kokiri forest.
There is a very, very tiny spot in the water there where you can swim. You can use it to get "SOL" as you call it.
I also noticed that it is possible to do it without backflip/sidehop. All you need is to get link to float towards the land while having ironboots equipped.
Normally this isn't possible of course, since link doesn't float if you just run towards the land.
However if you are below the water and equip ironboots the moment link surfaces from the water, he will float for a short time, while having ironboots equipped, just like when you do a sidehop/backflip.
From my own experience, it seems like you can do SOL at more places this way, since a sidehop/backflip doesn't always take you close enough to the land before the ironboots start to function.
It also works in the heart piece grotto, lol. :p
You should be able to do it in some temples aswell, but that is pretty useless.
Deku tree & water temple for example.
I can't seem to do it in the fishing pond and lost woods though,
