Trekking Poles
How to size, use, and actually benefit from them — they're not just for old knees.

When to use this
Always on descents longer than 500 ft. Optional on flat ground; beneficial on any terrain with loose footing.
- Hikes with significant descent — the biggest benefit is on the way down
- River crossings or loose terrain where balance matters
- Hikers with knee or ankle history, or carrying a heavy pack

What you need
- A pair of adjustable trekking poles (aluminum or carbon)
- Wrist straps used correctly (this changes everything)
Step by step
- 1.Size for flat terrain: hold the grip with the tip touching the ground beside your foot — your elbow should be at a 90-degree angle. Mark that length.
- 2.Shorten 5–8 cm for uphill (poles too long cause shoulder strain on ascent). Lengthen 5–8 cm for steep downhill (longer poles reach ahead of you and take the knee load).
- 3.Use the wrist straps: slide your hand up through the strap from below, then grip the pole. The strap takes the weight through the heel of your palm — you don't need to grip the pole tightly. Most hikers skip this and lose 80% of the benefit.
- 4.Uphill technique: plant both poles slightly forward, push down and back as you step through. Like a four-legged gait.
- 5.Downhill technique: plant poles ahead and slightly outward. As your foot strikes, the poles absorb a percentage of the impact — studies show up to 25% load reduction per step on descent.
- 6.On flat terrain: opposite arm-pole, same-side leg. Left pole forward with right foot. The rhythm becomes automatic.
Pro tips
- Lock the length before relying on them on a descent. A collapsing pole at full weight is a face-plant.
- Remove wrist straps before a river crossing. If you fall in, you want to release the poles immediately.
Common mistakes
- Gripping through the strap from above (thumbs-down). Strap should support the heel of your palm — thread your hand up through from below.
- Using the same length uphill and down. The adjustment is 5 minutes; the knee savings are substantial.
