These look interesting. I normally don't even give a second glance at any of the Z type poles because all the ones I had ever looked at weren't adjustable.  With these being adjustable I'd be interested in looking at them.

I have been using a pair of Black Diamond with the flip locks.  I like them because they are more adjustable than these. The range is from about 24 inches to 52 inches. They are also aluminum. I run where it's very rocky with a lot of places for the poles to get stuck between rocks. It happens all the time to me. I think Aluminum will flex a little better with out snapping than the carbon, although others may disagree with that. My poles have two small dents towards the bottom where they got caught between rocks. The force on them was pretty severe at the time and enough to cause the dent, but but didn't crack or shatter and are still fully functionable in regards to being adjustable.  I've often wondered if a carbon pole might have cracked or shattered.

The ones you are looking at will collapse into a shorter package then mine will.  They are also about 2 oz lighter.

Thanks for your input.  It's appreciated.

I went ahead and purchased the Leki poles and used them for the first time this past weekend.  I wasn't doing anything to really stress them, but they are incredibly light and very EZ to set up and break down, and I can see how using poles is going to be very beneficial for hill trail runs.
