How to craft elevated elusive / tailwind?

I haven't played in a couple years, don't really have time to dive into it. Can someone just explain how elevated mods are made?

Can it be added to existing boots, or are these not nearly as good as they used to be:

Elevated Mods come from using an Orb of Dominance. They raise one influenced mod by one tier (t1 becomes elevated) and delete another elevated mod. So you need influenced boots with at least 2 influenced mods and then it is a 50/50. Double elevated tailwind/elusive boots are made with your usual method by using an Awakener Orb and 2 pairs of influenced boots, now with the extra steps to elevate them beforehand.
