I know a lot of hikers have made the switch to trail runners or lighter shoes from heavy boots, as have I. Just curious as to what some of you are doing for winter when out for an extended time (a week or more) and encountering deep snow and ice? Plastic bread bags inside trail runners w/gaitors? Back to heavy or midweight boots? "Neos" Overboots? I have a pair of microspikes, but I don't think they will fit a heavy boot or overboot (size medium). Thanks.
