We have had about 2 inches of snow in stoke today so got a chance to try out my snow socks.
Anyone considering them that does most of their driving around town would definitely recommend them. They are easy to put on (5 mins if your hamfisted like me).
I've got some and 18" wheels and no arch clearance mean they're a nightmare to get on. They do work well, but it's having to take them off when you hit Tarmac that's a pain.
