Best Shoes for Flat Feet & Overpronation UK

Flat feet (pes planus) are more common than most people realise. Somewhere between 20% and 30% of adults have them. The arch collapses under your body weight, so the entire sole makes contact with the ground.

Flat feet aren't always painful, but they often cause problems through overpronation, where the foot rolls inward too much when you walk or run. That misalignment travels upward and can cause pain in the:

• Heels and arches
• Ankles
• Knees
• Hips
• Lower back

Left unchecked, overpronation can lead to shin splints, plantar fasciitis, bunions, and knee osteoarthritis. I see these knock-on effects regularly in my fitting room.

There are two types, and the distinction matters when choosing footwear:

• Flexible flat feet: the arch is visible when you're sitting or standing on tiptoe, but collapses under full weight-bearing. This is the more common type. Supportive shoes and orthotics usually manage it well.
• Rigid flat feet: the arch is absent regardless of position. Less common, and it may point to a structural issue. If this is you, get assessed by a podiatrist or orthopaedic consultant. Standard supportive footwear on its own probably won't be enough.

Here's what to look for when you're shopping:

• Motion control or stability features: medial posts, guide rails, or dual-density midsoles that limit the inward roll.
• Firm midsole with arch support: a structured midsole stops the arch collapsing further inside the shoe. Avoid soft, squishy midsoles that just compress under the arch.
• Wide toe box: flat feet tend to splay wider, so you need room up front. Without it, you're asking for bunions.
• Low to moderate heel-to-toe drop: 6 to 10mm works well. Very high drops can actually make pronation worse.
• Removable insole: lets you swap in a custom or off-the-shelf orthotic for better arch support than the factory footbed.

These are the shoes I find myself recommending most often for flat feet. All readily available in the UK.

I get asked about children's flat feet a lot. Here's the key thing: flat feet are normal in children under 8. The arch develops gradually through childhood, and most kids will develop a normal arch without any help.

What parents should know:

• Don't buy corrective shoes or insoles without a professional assessment. Unnecessary intervention can actually interfere with natural development.
• See a paediatric podiatrist if your child complains of foot pain, tires quickly during activity, or still has flat feet after age 8.
• Good, well-fitting shoes matter more than "corrective" ones. Look for a firm heel counter, secure fastening, and enough toe room.

Orthotics work well for flat feet, but what you need depends on how severe the problem is:

• Off-the-shelf orthotics: fine for mild to moderate flat feet. You'll find them for £15 to £80 at pharmacies and specialist retailers. Go for firm arch support, not soft cushioning.
• Custom orthotics: worth it for severe flat feet or when off-the-shelf insoles haven't helped. A podiatrist makes them from a cast or scan of your feet. Available through the NHS (GP referral to podiatry) or privately (£150 to £600).

To get NHS orthotics, ask your GP for a referral to podiatry. Wait times vary by region.
