My knees aren’t in the best shape, one in particular. I had a rather devastating 13 hour up-and-down hike on day two of a three day hike, and the last day my knees were hurting every step. What are some ways to take some load off the knees, or other ways to prevent this? Not including ‘taking more time for the hike’. Assume already decent footwear and some kind of stick to balance and spread weight.
Edit: Some good advice is given here, I accepted the answer with less obvious tips but be sure to read all the other answers too.
