Can anybody give a good explanation why trekking poles, such as the WalMart specials noted in
Trekking Poles, come with optional rubber tips?
Yesterday I had trail fever and did a day hike to Trail Camp. When I was getting ready to leave, a ranger walked up to me and looked at my trekking poles. I asked him what he was looking for, and he indicated that a number of people were hiking the main trail with the tips and that a number of dislodged tips have been found on the trail. (I was okay since I had normal tips on my poles).
Lo and behold, I passed a couple of hikers on the trail with the add-on tips. One of them was taking a rest so I confronted him on the subject.
