@Mom in NY I'm going to try diabetic socks. When I googled, I found that they were for people with circulation problems, etc. I don't like socks that leave a mark; I don't like the tightness.
Amazon has a lot of diabetic socks from a variety of companies, & I'm going to read the reviews, including those with pics. Lots of other places have diabetic socks too when I googled.
I have low blood pressure, and won't wear compression socks. Even when I bought the lowest compression, they sometimes make me feel light-headed.
I used to buy Legacy trouser knee socks and Louis Dell Olio's trouser knee socks from the Q because they were never too tight & never left a mark. Sometimes, the Louis D O trouser knee socks would creep down & I'd have to pull them up. Legacy was always excellent. I also used to buy Nordstrom's brand of ankle socks that were okay.
Let us know what you find.
