Why you need to break in your boots

This summer when I was on NOLS there was a girl on my course who didn't get a chance to really break in her boots. After a few days she had a blister we named "Ivan the Terrible." Even after we returned from the field, her foot still wasn't the same. We don't want to see any "Ivan the Terrbiles" on this trip, so even if you don't like the way your boots look, WEAR THEM ANYWAYS!
