I got these a few weeks ago. they weigh almost nothing are easy to adjust and cost enough that I can't blow off walking most nights now...
LEKI Micro Vario Carbon Trekking Pole Pair. They are 200.00 on Amazon
I'm 65 with back and knee problems. These help a lot. Much better upper body exercise and way less likely to fall over and hurt some other body part. Planning to use them as shooting sticks too.
