Now most everyone who uses trekking poles may already know this but just in case I figured I would put this out there. A couple weeks ago while doing a hilly loop, that @HalfTreaded can attest to, I saw another hiker with trekking poles going up one of the steep ascents. He basically had what I can only describe as a death grip on his trekking poles as he put his weight on them. This isn't the first time I have seen someone do this. Imo this isn't really the way to do it. The wrist straps are there not simply to make it difficult to lose a pole in my experience. Your hands should be primarily controlling the poles and, if you need to support weight with the poles as you hike, the wrist straps should be tensioned in a manner so that they support the weight you are distributing to the pole. There are obviously lots of different variations on this theme but this is the basic principle many of these other themes revolve around and since I have often seen this principle overlooked I figured I would put his out there.
