Will My Orthotics Fit in Normal Shoes?

If you've ever slid your orthotic into a shoe and felt your heel pop out, your toes jam against the front, or the whole foot rock sideways on top of the device, you're in good company. I see this in my shop almost daily.

The shoe is usually the problem, not your orthotic.

An orthotic takes up space. It adds height and volume that the shoe wasn't designed for. When there isn't enough room, you end up with pain, instability, and a device that can't do its job.

The good news? Plenty of normal, off-the-shelf shoes will work with orthotics. You just need to know what to check before you buy.

Before anything else, check whether the shoe has a removable insole. This is the number one requirement, and it's non-negotiable.

Your orthotic needs to sit flat on the midsole of the shoe, in the space the factory insole occupied. If the factory insole is glued down, your orthotic ends up stacked on top of it. That raises your foot too high, and you get heel slip, instability, and discomfort.

Quick in-store test: reach inside the shoe, grip the insole near the heel, and give it a gentle lift. If it comes away cleanly, you're good. If it resists or tears, the insole is glued and the shoe won't work.

This one check rules out most incompatible shoes before you even try them on.

A removable insole is essential, but it's not the only thing that matters. You also want:

• Enough depth: after removing the factory insole, there should be room for your orthotic plus your foot without feeling cramped across the top of the foot or toes.
• A firm heel counter: that's the rigid cup at the back of the shoe. Pinch it. If it collapses easily, it won't hold your foot securely over the orthotic.
• Adjustable fastening: laces, Velcro, or buckles let you fine-tune the fit around the instep once the orthotic is in. Slip-ons rarely allow enough adjustment.
• A stable, flat sole: avoid thick, squishy, or wobbly soles. Your orthotic works best on a firm, even platform.

Some shoe types are almost always a dead end. Save yourself the frustration:

• Court shoes and pumps: too shallow, fixed insoles, no way to adjust the fit.
• Flip-flops: zero structure. The orthotic has nothing to sit inside.
• Fashion trainers: many have glued-in insoles and soft heel counters. They prioritise looks over function.
• Ballet flats: far too shallow for any orthotic device.
• Slip-on loafers: no adjustable fastening means you can't secure the foot over the orthotic.

These are your best starting points:

• Lace-up trainers: the most reliably compatible shoe type. Most have removable insoles, firm heel counters, and decent depth as standard.
• Walking and hiking shoes: built for support, with removable footbeds and adjustable lacing.
• Lace-up work shoes: Derbys and Oxfords with removable insoles give you a smart option for the office.
• Some casual shoes: brands offering extra-depth or wide-fit ranges often include removable insoles. Check each shoe individually though.

If you've found a shoe with a removable insole but the fit still feels off, work through these steps:

1. Remove the factory insole completely. Don't leave it in the shoe underneath your orthotic.
2. Check the orientation. Make sure the orthotic is sitting flat with the heel cup aligned to the back of the shoe.
3. Loosen the lacing. Retie the shoe with a bit more room across the instep, then tighten gradually.
4. Consider going up half a size. A slightly larger shoe can make a real difference with a thicker device. See our guide on what shoe size to buy with orthotics for detailed advice.

Buying for a child? Children's feet and orthotics have different requirements. Read our guide on whether orthotics will fit in your child's shoes.

Use this checklist every time you shop. If a shoe passes all five checks, it's very likely to work with your orthotics:

• ✓ The insole lifts out cleanly without tearing
• ✓ There is enough depth for the orthotic plus your foot
• ✓ The heel counter is firm and does not collapse when pinched
• ✓ The shoe has adjustable fastening (laces, Velcro, or buckles)
• ✓ The sole is flat, firm, and stable

Can I put my orthotic on top of the existing insole?

No. Stacking your orthotic on the factory insole raises your foot too high inside the shoe. You'll get heel slip, instability, and discomfort. Always remove the factory insole first.

My orthotic is larger than the shoe's insole. What should I do?

Try going up half a size. If that doesn't sort it, speak to your orthotist about trimming or adjusting the device to match the shoe's footbed shape.

My orthotics fit in my trainers but not my work shoes. Is there a solution?

Work shoes are typically shallower than trainers. See our guide to work shoes for orthotic wearers for options that look smart while accommodating your device.

Will any UK shoe brand definitely work with orthotics?

No single brand guarantees compatibility across its entire range. It depends on the individual model, not the brand name. Always check each shoe against the features checklist above.
