It would take more than 5-6 days to pack out. You say it's snug but how is the volume? My feet touch the front of my boot but I have a low volume foot, wide feet (in the middle not toes), and really skinny ankles and heel. So I get foot slop unless I stuff foam up the yin yang.
My feet are also wide. The boot feels tight all around but I do get a little heel lift sometimes on a really hard turn on the toe edge. Only my back foot gets heel lift though. Maybe we hhave a similar problem. How did you fix it?
