Trekking poles aren't just a stability aid — they're one of the most effective, evidence-backed tools for protecting your knees on the trail. Research on downhill hiking consistently shows that proper pole use reduces the compressive force on your knee joints by up to 25%, transferring load to your arms and upper body instead.
The science is clear, but most hikers still use poles incorrectly — wrong length, no wrist straps, planting too far ahead. Technique matters as much as the poles themselves.
The Science: What Research Shows
Three numbers every hiker with knee concerns should know.
25%
Knee Force Reduction
Proper pole technique reduces compressive force on the knee joint by up to 25% on descents.
13 kg
Removed From Each Stride
On a loaded descent, poles can transfer up to 13 kg of impact force away from your knees and into your arms with every stride.
3-4x
More Stress Downhill
Descending generates 3 to 4 times more stress on your knees than walking on flat terrain — precisely where poles help most.
Force on Your Knees — With vs Without Poles
Relative compressive force during a loaded descent.
Full impact force transmitted directly through the knee joint with each downhill step.
Roughly a quarter of the load is redirected through the poles into your arms and shoulders.
Pole Types: Folding vs. Telescoping
Folding (Z-Pole)
Pros
- ✓Packs down small — fits in or on a backpack easily
- ✓Lighter average weight than telescoping poles
- ✓Fast to deploy — just unfold and lock
Cons
- ✕Fixed length or limited adjustment range on most models
- ✕Repair in the field is harder if the internal cord snaps
- ✕Generally more expensive than telescoping
Telescoping
Pros
- ✓Fully adjustable length — ideal for steep ascents and descents
- ✓Easy to repair or replace sections in the field
- ✓Usually more affordable
Cons
- ✕Bulkier when collapsed — doesn't pack as small
- ✕Locking mechanisms (twist or lever) can loosen or fail over time
- ✕Slightly heavier on average
Materials: Aluminum vs. Carbon Fiber
Aluminum
Aluminum poles bend under extreme lateral stress rather than snapping — a safer failure mode in the backcountry, since a bent pole can often be bent back into a usable shape.
Carbon Fiber
Carbon fiber is significantly lighter and dampens trail vibration better, but it can snap suddenly under high lateral force — a real risk on technical, rocky terrain.
Grip Materials
Cork
BestMolds to your hand shape over time, wicks moisture and sweat effectively, and stays comfortable on long, hot days. The top choice for most hikers.
EVA Foam
GoodSoft, lightweight and inexpensive. Absorbs shock well but retains moisture and compresses faster than cork over time.
Rubber
Cold WeatherInsulates the hand from cold metal shafts and provides a secure grip with gloves — but tends to cause blisters and retain heat on warm days.

Technique: How to Actually Use Them
- 1
Correct Length
Elbow should form roughly a 90° angle when the tip touches the ground on flat terrain — shorten poles ~5–10 cm for steep descents, lengthen for climbs.
- 2
Use the Wrist Straps
Slide your hand up through the strap from below so it supports your wrist — this lets you relax your grip and transfers load through the strap, not just your fingers.
- 3
Planting Rhythm
Plant the pole opposite your leading foot, in a natural alternating rhythm — like an extension of your arm swing, not a separate deliberate motion.
- 4
Tip Angle on Descents
Plant the tip slightly ahead of your body on descents, angled forward, to brace against the slope and absorb impact before your knee does.
Poles don't eliminate risk: they reduce load, not danger. On exposed scrambles or when you need both hands free, stow your poles. Never rely on poles alone for balance on unstable terrain.
The biggest technique mistake is planting the pole too far forward and pushing off too late. Practice a short, quick plant close to your body — it's more efficient and puts less strain on your shoulders over a long day.
