I've used poly liner socks for decades, Ultimax brand. I call them slip socks, because, as Harvey says, it provides an extra mechanical/physical sliding layer. Then Merino wool socks over that. And I carry Millipore paper tape, but only ever used it to patch up other folks with inadequate sock systems...
