I have used the sock before, but I had issued getting it to stay in...I have used vet wrap with better sucess, but if it gets waterlogged it turns into gum..
SStack. Has gaurd-tex. Its like vet wrap, but not strechy and doesnt gum up. Problem with that is its only available in 4 rool packs and its like $25.
I havent found it anywhere else.
With the socks, I cut them at the top to make four long strands and tie them up near the dock, crossing the back left strand to tie with the front right strand and right back to the left front. I change them every month but they would last much longer if I allowed them to.
