I have been using these as part of my rehab after head trauma. The ones in use at the rehab centre are identical to these from Trekrite in every way except price. Fully telescopic and adjustable to suit the individual and spring loaded to absorb shock should you wish to use it. Perfect for my needs and as me and my partner are avid walkers, they will not become an item for the cupboard, but will be used for many years to come.
If you are looking for hiking poles, you could do a lot worse than these little beauts.
Delivery time was excellent too.
