I'm planning on doing a 2-day/1-night Presidential Traverse in either January or February with a couple friends. I have a pair of La Sportiva Nepal Evo boots that I used last winter in the Whites and on Rainier in August. Will these be warm enough? Or do i need double plastic boots? My feet haven't been cold in them yet. But, I've also never done a hike being exposed to the elements for so long in super cold condition. I used them this winter on a 2-day attempt at the Bonds and I was fine. We camped one night but had to cut the trip short due to an injury.
I don't like the idea do renting plastics and trying them on such a big hike. I did a 1-day traverse in the spring of this year.
