What are the best trekking poles for bad knees on UK trails?

If you have bad knees, hillwalking can feel like a balancing act between the joy of the hills and the fear of pain. The good news is that the right trekking poles can be transformative—they can significantly reduce the impact and strain on your joints, allowing you to walk further and with less discomfort. The short answer is that the best trekking poles for bad knees are 7075 aluminium poles with lever-locks, comfortable cork grips, and a lightweight but durable design. However, the real game-changer is how you use them. This guide covers the best poles, the key features to look for, and the techniques that will save your knees.

The Biomechanics of Knee Pain

Understanding how poles help is the first step to choosing the right ones. Every step you take, especially on a descent, sends a shockwave up through your leg. This impact force is the primary culprit behind knee pain.

• On a Descent: The impact force can be two to three times your body weight. Your quadriceps act as brakes, and your knee joint absorbs a significant portion of that shock.
• The Role of Poles: When you plant a pole and push, you transfer a portion of your body weight from your legs to your arms and upper body. This reduces the load on your knee joint. Studies have shown that using two poles can reduce knee impact by up to 25% on descents. This is a profound difference.

Key Features to Look For

1. Material – Aluminium, Not Carbon

7075 aluminium is the best choice for those with bad knees. It offers a subtle but important benefit: it flexes slightly under load. This micro-flex absorbs a tiny amount of shock before it reaches your arms and shoulders. Carbon fibre, while lighter, is stiffer and transmits more vibration, potentially increasing the jarring effect.

2. Locking Mechanism – Lever-Locks

Lever-locks are more reliable than twist-locks, especially in the wet, muddy UK conditions. A slipping lock is a safety hazard—it can cause you to lurch and put unexpected stress on your knee. Lever-locks are also easier to adjust with cold hands, which is crucial when you need to quickly change length on a descent.

3. Grips – Cork or Comfortable Foam

You will be gripping these poles for hours. A comfortable, non-slip grip is essential.

• Cork: The best choice. It moulds to your hand, becomes tackier when wet, and absorbs sweat.
• High-Quality Foam: A good alternative, but it can become slippery when soaked.
• Rubber: Avoid—it becomes dangerously slippery in the wet.

4. Weight – Light but Durable

The poles themselves should be light enough that you don't feel fatigued swinging them, but robust enough to handle the terrain. Aim for the 240‑280g per pole sweet spot.

5. Shock Absorbers – Probably Not

While shock-absorbing poles might seem like a good idea for sore knees, they are often more trouble than they are worth. The springs add weight, make the pole feel mushy on descents, and can fail. You are better off with a rigid pole and relying on your own technique and bent elbows to absorb shock.

The Knee-Saving Technique

The best pole in the world is useless if you don't use it correctly. Here's how to use your poles to protect your knees:

1. Lengthen on Descents: This is the single most important adjustment. On a steep descent, lengthen your poles by 5‑10 cm from your flat-terrain setting. This allows you to plant the pole ahead of you and use it as a brake, transferring the impact to your arms.
2. Plant Ahead: Plant the pole ahead of your foot, not beside it. This creates a backward angle that helps you brake.
3. Use the Straps: Thread your hand up through the strap. The strap should take the load, not your grip. This allows you to push down through the pole without tiring your hands.
4. Double-Plant on Steep Ground: On very steep descents, plant both poles together ahead of you, take a step, and repeat. This creates a stable, three-point stance that minimises impact.
5. Soft Arms: Keep your elbows slightly bent. This allows your arms to act as shock absorbers, further reducing the load on your knees.

Maintenance for Knee-Friendly Poles

• Check Locks: Loose locks are a hazard. Check the tension screw on your lever-locks before every walk.
• Clean and Dry: Mud and grit can cause locks to slip. Clean your poles after every walk and dry them thoroughly.
