Used it in Chadar Trek, Very useful worked very well I loved it antishock property. However, its opening and closing froze a few time due to ice.
My parents-in-law bought two poles for me as a Christmas gift but they do not tighten at all - they unscrew but the sections come apart - should they have springs in as mine do not.
Great value product
Any wide Sport shoes
It was slightly heavier than other models, but I preferred the anti-shock spring feature of this model. Also, the grip design is very comfortable and natural.
The antishock makes the pole a little heavy, but the spring feeling that it gives is worth it.
The height adjustment system was a bit confusing at first, as it seems like you should twist the blue rings when you should in fact twist the poles. But once used to it, it's great because the height can be adjusted precisely, it's not restricted to specific steps.
