Don't laugh at this suggestion but I have been using trekking poles I bought in 2017 at Walmart! They have a cam lock style that has held up incredibly well in the Badlands, numerous high altitude elk hunts and are dirt cheap. The last time I saw them they were $19 for a pair. Lots of threads on LRH about their durability. I am 6'4" 260 with spinal stenosis and spinal arthritis so I depended upon them hard. I use to buy $75-$100 trekking poles each that didn't hold up as well. Check them out! Hopefully they still carry them!
