"I think that Komperdell made these for REI, actually. Whoever is responsible for them did a good job. No shock absorbers on these...they're just the basic Summit poles. After a few years of use I've noticed that I've picked up some grit in the tightening mechanism, so I'll need to clean them before that does some damage. And the very-smooth plastic grips do get a bit slick when wet. I have noticed that they keep my fingers and arms from getting cold from lack of action, and on ascents and descents they save my knees and ankles a lot of impact. They're helpful for balancing across rushing streams and sucky mud as well.

"After spending 4 days in the Yosemite National PArk backcountry, I can say that the trekking poles we purchased were the best investment ever. Although other people were making fun of us, we were the ones crusing up and down the swithbacks with relative ease. As long as your hike is in a hilly area, get em' otherwise leave em' at home"
"Due to recent injury to my knees I decided to try a pair of trekking poles. I am now kicking myself for not getting some 20 years ago (did they exist 20 years ago?). They would be unnecessary for relatively level trails, but for when the trail turns ugly, or for those of us who get off the trail as soon and often as possible these things are excellent! They provide much more stability and balance, and allow you to put a bit of your weight on your arms while ascending or descending. They are especially useful when crossing snow (or mud). I don't recommend any particular brand but don't think shock absorbing springs are necessary (does anybody remember the Allsop "shock absorber" ski poles?). Cork based grips might be nice, but I would avoid the natural rubber ones; they tend to leave a layer of sticky stuff on my hands. The REI poles I have are 3 piece aluminum with a soft plastic grip and cost $60.00/pair."
