Do You Actually Need Trekking Poles?
Poles aren't just for older hikers — research shows they reduce knee stress by up to 25% and improve stability on any terrain. Here's how to decide and what to buy.
Trekking poles are one of the most debated pieces of hiking gear. Skeptics see them as unnecessary complexity; converts swear they can't hike without them. The biomechanical research is fairly clear: poles reduce impact forces on knee and hip joints by 20-25%, improve balance on uneven terrain, and allow upper-body muscle engagement that reduces lower-body fatigue on long days. Whether you need them depends on your terrain, load, and physiology.
The Research: What Poles Actually Do
Multiple biomechanical studies show trekking poles reduce compressive forces on the knee joint by 20-25% on descents. They distribute load to upper body muscles, delay lower-body fatigue, and improve stability — particularly with a loaded pack. On technical terrain, they provide two additional points of contact that dramatically reduce fall risk. For hikers with knee issues, weak ankles, or heavy packs, poles are genuinely functional rather than optional.
When Poles Are Most Valuable
- Steep descents — the highest knee impact situation in hiking
- Stream crossings — balance and probing depth
- Heavy pack carries — distributing load to arms
- Technical scrambling — four points of contact
- Loose terrain (scree, gravel) — stability on unstable surfaces
- Snow travel — probing snow depth, balance on ice
Types of Poles
Adjustable poles (twist-lock or external lever-lock) allow you to change length for ascent vs. descent — slightly shorter uphill, longer downhill. Fixed-length poles are lighter but less versatile. Folding poles pack small and are popular with trail runners and ultralight hikers. The lever-lock system (Black Diamond Flick Lock) is more reliable than twist-lock for longevity. Carbon poles are lighter and absorb vibration better than aluminum; aluminum is more durable and cheaper.
Proper Pole Length
The general formula: elbow at 90 degrees when holding the pole with the tip on flat ground. On steep ascents, shorten by 5-10cm; on steep descents, lengthen by 5-10cm. This adjustment matters — poles that are too long force your shoulders up, causing neck and shoulder fatigue. For taller hikers (over 6'), look for poles with maximum adjustability.
The Technique Matters
Most beginners use poles wrong. The correct grip: wrist through the strap from below so you can push down on the strap rather than gripping tightly. On ascent, plant the pole slightly behind you for propulsion. On descent, plant slightly ahead for braking and balance. On flat terrain, poles should swing in opposition to your feet — right pole plants when left foot strikes, creating natural spinal rotation.
