I need long socks that comfortably fit - at the moment , one is fine but the other rolls down as when I buy them in a standard shop they are slightly too tight. I have one pair that are woolly and cable- they are stretchy and I think they must be over the knee ones as they have extra at the top. I literally have no idea where I got them from unfortunately as they are old. Where can I find nice stretchy plus size boot socks?
