“Keep your heels down.”
“Relax your knees.”
“Stretch your leg.”
If you’ve heard these instructions countless times but your lower leg still swings backwards, your heels keep creeping up, or you constantly lose your stirrups, you’re not alone.
Many riders assume they have a weak position or simply need more practice. In reality, one of the most common causes is something much simpler:
Your stirrup length may not match your body or your saddle.
Surprisingly, many riders spend years trying to improve their position while riding with stirrups that are either too long or too short. And the problem isn’t just your stirrups. It’s the combination of your anatomy, the saddle design and the position of the knee blocks.
Do you recognise these problems?
- Your lower leg swings backwards.
- Your heel won’t stay down.
- You grip with your knees.
- Sitting trot feels difficult.
- You constantly adjust your feet in the stirrups.
- Your instructor keeps telling you to “keep your leg underneath you.”
If several of these sound familiar, there’s a good chance your stirrup length deserves a closer look before you spend more time correcting your position.
Why the traditional advice isn’t always correct
Most riders have learned the classic rule:
“The stirrup should reach your ankle bone when your feet are out of the irons.”
It’s a useful starting point.
But it is not a fitting method.
Two riders with the same height can require different stirrup lengths because of differences in:
- Femur length
- Tibia length
- Hip mobility
- Ankle flexibility
- Saddle design
The goal isn’t to achieve a certain stirrup length. The goal is to create a position where your body can remain balanced without muscular tension. And that’s where many riders unknowingly go wrong.
Before adjusting your stirrups…
Before you shorten or lengthen your stirrups, ask yourself these questions:
✔ Are you sitting in the deepest point of the saddle?
✔ Is your pelvis neutral?
✔ Are your shoulders balanced over your hips?
✔ Is your lower leg naturally underneath your body?
If not, changing your stirrup length alone won’t solve the problem.
