Best Shoes for Knee Pain: What the Evidence Actually Supports

Flat flexible shoes were standard advice for knee osteoarthritis until trials tested them. What to buy instead, from a foot and ankle surgeon.

Be honest about how much a shoe can do

The foot is the interface between you and the ground, so it is intuitively obvious that what you put on it changes what happens at the knee. That intuition is correct in the laboratory: change the shoe and you measurably change the forces at the knee joint.

What is far less clear is whether those measurable changes translate into people hurting less. They often do not, or they do so by a small amount. Anyone selling you a shoe as a treatment for knee pain is overstating a real but modest effect. Buy the shoe — it is cheap, low-risk and worth doing — but buy it alongside the things that actually shift knee pain, which are progressive strengthening, managing how much you do and how fast you increase it, and weight where that is relevant.

The flat flexible shoe claim, and what the trials found

For years the advice for knee osteoarthritis leaned towards flat, flexible, minimally supportive shoes, on the reasoning that they reduce the load passing through the inner compartment of the knee. The biomechanics behind that were sound enough.

Then it was tested properly. When flat flexible shoes were compared head to head against conventional stable supportive shoes in people with knee osteoarthritis, the flat flexible shoes did not come out ahead. The supportive shoes did at least as well on pain — and were better tolerated by a good number of participants.

This is worth stating plainly because the older advice is still repeated widely. If someone has told you to buy the flattest, most flexible shoe you can find for your knees, the evidence does not currently support that. A comfortable, supportive, cushioned shoe is the more defensible default.

What to actually look for

1. Genuine cushioning under the heel

Every heel strike sends a load spike up the leg. A midsole with real depth attenuates it. Depth matters more than softness: a thin layer of very soft foam bottoms out under body weight and stops absorbing anything, whereas a taller stack of moderately firm foam keeps working. Our Hoka versus Brooks comparison shows how the shoe with the biggest cushioning reputation actually uses the firmer foam of the two and gets its cushioning from height.

2. Stability that matches your foot

If your foot rolls inward markedly as you load it, the shin rotates inward with it, and that rotation arrives at the knee. For people who pronate heavily, a stability shoe can reduce that. For people who do not, a stability shoe adds control nobody asked for and can feel harsh. This is why blanket recommendations fail: the right amount of support is the amount your foot needs. Our walking shoe guide covers how to work out which group you are in.

3. A rocker sole

A curved forefoot rolls you through the last part of the step instead of demanding the ankle and forefoot bend to push off. It reduces the work at the end of stance and, for a lot of people with knee pain, makes walking distances noticeably easier. It is one of the more reliably appreciated features in this category.

4. A shoe you will actually wear

The best-designed shoe in the world does nothing in a cupboard. Comfort on the first wear predicts whether people keep using footwear better than almost any technical specification. If it is not comfortable in the shop, it will not become comfortable at home.

Lateral wedge insoles: probably not

Wedged insoles that tilt the heel outward were widely promoted for inner-compartment knee osteoarthritis, on the same load-shifting logic. They do change the loading a little. Reviews of the clinical trials have generally not found a meaningful pain benefit, and major osteoarthritis guidelines do not recommend them routinely.

That is not the same as saying nobody responds. It is saying that if you try them and they do nothing after a few weeks, that is the expected result rather than a sign you have done it wrong — and it is not worth spending a great deal on them speculatively. If your knee pain sits on the inside of the joint and you want to try something in the shoe, do it with a clinician who can check whether it is helping.

Where the knee pain is changes the emphasis

• Inside of the knee, worse on stairs and after walking. The commonest pattern with medial compartment osteoarthritis. Cushioning, comfort and a rocker. Strength work at the hip and thigh is the main treatment.
• Front of the knee, worse going downstairs, after sitting, or squatting. Patellofemoral pain. Cushioning helps; so does anything that reduces how much load you put through a bent knee. Shoes matter less here than loading and strength.
• Knee pain that started when your feet changed. A collapsed arch, a new flat-footed posture, or a foot problem that has changed how you walk can genuinely refer trouble upward. Our high arch guide and the walking guide cover the foot side.
• Knee pain plus foot pain. Treat the foot properly — limping to protect a painful foot loads the other joints. See the relevant condition guide first.

Skip it if

• Your knee locks, gives way, or is significantly swollen. That is an assessment, not a shoe.
• You are buying footwear instead of doing the strengthening. This is the honest one. Shoes are a small, cheap, worthwhile adjustment. Muscle around the joint and sensible load progression are where the improvement comes from.
• You have been told to buy the flattest, most flexible shoe available. The trial evidence does not support that as the default.
• It is uncomfortable in the shop. It will not improve, and you will not wear it.

This page is general information, not a diagnosis or a treatment plan. Persistent knee pain — particularly with swelling, locking, giving way, or pain that wakes you at night — should be assessed in person.
