Query: A liner

It's a liner, not a thick stand alone sock. I wear them underneath my full thickness gold toe socks and they are really comfortable that way. They are very thin which allows my feet to move a little within my shoe. I'm on my feet all day in a factory and I quite like these as an accessory kind of sock/sleeve.Glad I bought the largest size, they are still very snug...I would say the sizing runs on the small side.
