I would not worry about your toenails falling off from a hike even if it was a long one. I am sure your feet are just bruised from the really long hike. In all my years as a nurse I have never seen a case of someone losing their toenails from hiking. I saw a lot of people slam their fingers or toes and lose a nail. From hiking, never saw one person.
