Can flat feet cause knee pain?

If you have flat feet and your knees have been complaining lately, you may be wondering: are these two things connected? The answer is yes, they absolutely can be. Your feet are the foundation of your body. When that foundation isn’t properly supported, the effects can travel upward. First the ankles, then the knees, and sometimes even the hips and lower back can start hurting. The good news? Proper support is the first step toward feeling better.

What are flat feet?

In short: flat feet occur when the arches of your feet collapse or never fully develop. This causes most or all of the sole of your foot to touch the ground when standing.

Some people have flat feet their entire lives without any problems. Others notice symptoms such as foot fatigue, heel pain, swollen ankles, aching arches, knee pain, or even hip and lower back discomfort.

Can flat feet cause knee pain?

Yes, they can. When your arches collapse, your feet tend to roll inward more than they should. This is called overpronation. This changes the alignment of your legs and can put extra stress on your knees.

Over time, this disturbed alignment can lead to:

Pain around the kneecap
Increased wear and tear on the knee joint
Stiffness after walking or standing
Discomfort when climbing stairs
Achy knees at the end of the day

Why support matters for your knees

For years, comfort has been confused with softness. Sure, squishy shoes can feel nice for a moment. But your feet (and the rest of your body) need support just as much as cushioning.

Good supportive shoes help:

Keep your feet in a more natural position
Encourage proper alignment of your ankles and knees
Reduce strain on joints
Make walking easier and less tiring
Help you stay active and comfortable throughout the day

Don't ignore knee pain

Occasional aches happen, but persistent knee pain isn’t something you should simply “walk off”. If your symptoms are severe or worsening, it’s always wise to consult a healthcare professional.
