Andrew Skurka officially recommends the Cascade Mountain Tech Quick Lock Poles. He puts in a lot of miles, so they're pretty durable.
I've had a set of the foam-handled ones for a few years now. I'm pretty sure I've put more than 400 miles on them and they're still going strong so you can add my recommendation too :) Hard to beat for $36 on Amazon :)
Light weight, durable and economic - using two helps me more than double the time I can spend on my feet! https://www.amazon.com/gp/product/B00EJP43FA/ref=ppx\_yo\_dt\_b\_asin\_title\_o00\_s00
