Im just an oddball. I hate trekking poles and am not fond of super stiff soled "mountain boots" (cant feel whats under foot).
I was crossing a very steep avalanche chute last July and between the poles and the stiff boots I just about met my maker. Couldnt feel just how loose the rocks were under that 2x4 of a sole and started to go down. Normally I would have just flopped down flat as a pancake, but I got tangled up with a friggin pole and ended travelling a little farther than expected.
Than they're always tangling in the brush and such when you arent on a decent trail, getting hung up in deadfall, etc. Or you get to a really steep grade where its pretty much a hands and knee climb up, and you either got screw around breaking em down and stowing em, or they're flopping around in the way on your wrists. I dont really swing my arms when I walk, so it was really weird to me to be "skiing" while walking with all that arm movement. Poles for me end up up "skipping" off the ground a lot when I reach out in front with them, just a really un-natural movement for me with all that arm movement.
For a heavy load I can definitely see where they'd be handy, but unless I got 100 lbs on my back, they arent for me.
