honestly, i just use duct tape, twice around each foot. i ride with a swiss army knife in my right hand and i'm fairly adept at cutting myself out on the fly.
granted, i have to ask for assistance if i want to get taped up in a hurry, but most people in tally are pretty nice about helping others out.
although, for snow, i would definitely go with a waterproof tape, like packing tape maybe. you may have to wrap it more, but it will stay until you cut out.
good luck!
