Tight socks making POTS symptoms worse, what are you using?

My legs feel worse in tight socks and I've been trying to find something that provides some support without restriction. I went through a few athletic brands before someone mentioned diabetic-specific socks as an option because of the non-binding design, and he top doesn't tighten even when my legs are more swollen than usual. Not a medical solution but for everyday comfort it's been the best option I've found so far
