The snow socks can be tricky to put on if you don't jack the wheels all the way up,..a bit like putting on a pair of glove blindfolded. You need 2 person for the job..one to drive back and forth while the other person has to give instruction. That's only way you could get the rest of the socks on. It's a one man's job if you jack the wheels up. Realistically, can't do this at the hard shoulder all the time-it's just impractical. Have a look at the snow chain youtube..looks much easier..there is no need to drive the car few inches away just to get the rest on. Only downside of the chain is i'm unsure about the clearance under the wheel arch..definitely not an option for those who had lowered their Zed.
