>>160930552. Knees bother me, but not unbearable
Do backpacking trips of >70 miles most summers, including this summer
I still do talus and scree
Downhill is always a problem, but I slow down and place my feet carefully
I use a hiking pole
I bring 2 pairs of socks and wash a pair daily to keep them fluffy
At home I rotate my sneakers so that I don't wear the same pair every day and toss out the oldest pair every 4 months
I have walked at least a mile every day for the past 25+ years
I do my shopping by foot, so I carry a heavy load on my back at least once a week
I take MSM and glucosamine occasionally
Hope some of this helps
