can adjust. I'm a fan of the hiking poles with the shock absorbers in them, and they're pretty cheap. Not sure if you have used poles before but if not watch a video like this: https://www.youtube.com/watch?v=7q2YwOE4okA

Many people make the mistake of having the their grip set wrong (like he starts showing at 2:18) and it doesn't help with locomotion. It makes a huge difference for me to have gotten the adjustable poles and learned how to adjust to the correct height and how to correctly configure the strap to help provide forward momentum. 2 years ago we hiked TMB which is 110 miles and having the pole set up made a huge difference. When we did Grandy Canyon rim to rim like 5 years ago I did NOT know how to use/adjust poles and it made a big difference. I cant overstate how much difference it makes for me.

Edit: here are the poles I use that I got on Amazon and they're under $30. Aihoye Hiking Trekking Poles, 2 Pack Collapsible,Lightweight, Anti Shock, Hiking or Walking Sticks.

(The only thing I dont like is that they dont have a wider/cushioned wrist strap, so I'll buy similar poles before our next big hike that have a padded wrist strap)
