The value of trekking poles is the improved stability they provide to the hiker. This is particularly helpful while traversing across sloped, uneven or slippery terrain. They transfer shock away from joints and ease the workload of your legs. Once you try trekking poles you will never do without them!
Features of Trekking Poles
The common length of trekking poles is between 25 to 56 inches (55 to 123 centimeters) and the weigh is 16 to 20 ounces (454 to 567 grams). Shafts are typically made using a lightweight aluminum or carbon fiber. Some of the manufactured type have been designed to retract. Built in clips give them the added convenience of being able to attach to the side of a pack. When hiking long distances on a slope, the "uphill" pole can be shortened to compensate for the difference in distance. During a descent they can easily be extended for extra length needed to provide the hiker a braking action.
Common Options for Trekking Poles
Optional features include the ability to turn off or lock the shock absorber for the ascent when you need power, and engage it for the descent when used for braking. Spring tips reduce wrist impact by adding spring or cork to cushion the jarring effect while walking. A nice feature a camera clip for mounting a video or digital camera above the grip. Some trekking poles have shafts with extension length markers so you can preset set the length to match your height
