i believe there was a company years ago that made sock "garters" for fire service. like ladies langere that held there stockings up only it was at the knees for socks. i can't say if they did or not most my time was volenteer and if i actually had socks on it was a miracle
I have the same problem when I wear waders, I bought a pair of neoprene cuffs I guess you could call them, they are Velcro and you tighten them around the top part of the sock and it keeps them up. Love em.
Don't Tread On Me is what it says and I'll take that to my grave.
