Any thoughts, opinions, experiences on using these for backpacking, around 45lbs pack, 3 day trip?
Merrell Chameleon 4 Stretch. Has vibram sole



We'll be on a pretty tramped down trail in the Arkansas Ozarks. I just bought them and am wearing them around the house with a weighted (40lb) backpack. Comfortable so far, I got a half size bigger to make up for foot swelling.

There's no ankle support, but we're not doing anything hardcore, plus I do barefoot running (minimal shoes) so I feel my ankles are pretty strong.

Here's a link to the description:
