I was hiking the Milford Track in NZ a few years ago, and there was one Kiwi on the trail who had to do it in flip flops because one of his big toes was all mangled from some accident a few days before. He achieved legendary status amongst the other hikers on this trip who were finding it a challenge in sturdy hiking boots. He had strangers coming up to him for days to inquire on the toe. He was genuinely surprised at everyone's concern. You should have seen that toe!
He put a little ointment on it but no bandage because they kept falling off as he hiked. Just a mangled toe, open to the air, on a 4 day hike.
