I bought a pair of Catbells poles at the last minute before a trip to Nepal. My very old and tired poles had failed, so I ordered th very late. Kate and the te rushed them out to me and I have been very impressed. Easy to use, light for aluminium, and comfy.
We were only doing day treks, but with steep gradients poles always help!
They were also used by an older member of our party who was suffering on the descents.
Easy to adjust for different heights.
Overall very pleased, so far...
I have a 3 day ultra next month so will update on how they perform running
