Got the vx socks at home, unopened.
Having sc3's, which I now know to frankly dangerous in snow, after sailing through a red light having left loads of stopping distance in fresh 5a.m. snow, and having realised that getting to the top of my road, 400yards slight up hill, with constant right turn, with a hill start at the top on to a main road, that o needed something to aid traction.
A full LPG tank, a full petrol tank, and a load of tools in the boot didn't help. After the snow cleared I was in the dealers. Snow sox bagged. Sat in the packet ever since.
All I know is, abandon all hope all ye who drive on snow with sc3's.
I suspect snow sox will help me get to the top if my road if it snows heavy enough.
That's all I can expect from them, and is all I bought them for.
IMO snow chains serve similar purpose, given my location. Your location will be differant obviously, depends how close you live to a bus route, as that will get gritted first.
Sadly no chains available when I was looking to buy, which was 3 days after the snow, grid lock, and the country had shut down.
