I have Polyneuropathy caused by an autoimmune disease.
My feet are a patriotic red, white, and blue most of the time.
I found sock on Amazon that are like wearing a comfy sweater on your feet. They are cotton (no wool).
The brand is Polar Extreme. They are a bit pricey. I actually bought mine from a discount store (Ross).
There are others made by Columbia.

I also have lymphedema along with idiopathic small fiber PN. I have to wear compression socks which are thin. After struggling putting them on when I was first diagnosed, I found some on Amazon with a zipper in the side that make them easier to put on and have been using them for the past 5 years or so. I recently found a 2 piece compression sock set on OrthoFeet.com that are easier to get on. You put on the compression foot/ankle sock first and then slide on the calf sock over the ankle sock. Neither make my neuropathy feel better. Before the lymphedema was diagnosed I found that socks made with bamboo fiber were really comfortable on my feet. In the winter when my feet are cold, I've found that HotHands Insole foot warmers really keep my feet warm so I keep some around for the colder winter days when I have to go outside - https://www.amazon.com/HotHands-Insole-Foot-Warmers-Activated/dp/B001UQXAT6/
