I am all for adding more gear to my collection if it makes for a more comfortable hiking and/or camping experience, but I question the benefit of buying trekking poles. I have never owed a pair.
In 30+ years of camping and hiking, I have only felt the need to have trekking poles on 2 occasions. Once was while hiking on a glacier in Alaska and once hiking on a snow and ice-covered trail in Switzerland. In those situations, I thought the poles would have likely added more stability.
I have tried them out on a few spots in the southern Appalachians in fairly steep terrain and I have also tried them out in very moderate terrain, and I just didn't feel like they helped much at all.
Am I missing something?
Trekking poles seem to be very popular these days, but are they actually beneficial, or more of a fashion statement?
