Will My Orthotics Fit in Normal Shoes?

If you have ever slid your orthotic into a shoe and immediately noticed your heel popping out, your toes being squeezed, or the whole foot rocking on top of the device, you are not alone. This is the single most common frustration for orthotic wearers in the UK.

The problem is not your orthotic. It is the shoe.

An orthotic device takes up space inside the shoe. It adds height, width, and volume that the shoe was never designed to accommodate. When the shoe cannot handle that extra volume, you get pain, instability, and a device that cannot do its job properly.

The good news is that 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 for orthotic compatibility, and it is non-negotiable.

Your orthotic needs to sit flat on the bottom of the shoe, directly on the midsole. If the factory insole is glued in place, your orthotic will sit on top of it, raising your foot too high inside the shoe. The result is heel slip, instability, and pain.

Quick in-store test: reach inside the shoe, grip the edge of the insole near the heel, and give it a gentle lift. If it comes away cleanly, you are good. If it resists or tears, the insole is glued and the shoe will not work.

This single check will rule out the majority of incompatible shoes before you even try them on.

A removable insole is essential, but it is not the only thing that matters. For the best results, look for all of the following:

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

Some shoe types are almost always incompatible with orthotic devices. Save yourself time and avoid:

• Court shoes and pumps: too shallow, no removable insole, no adjustable fastening.
• Flip-flops: no structure whatsoever; the orthotic has nothing to sit inside.
• Fashion trainers: many have glued-in insoles, soft heel counters, and prioritise looks over function.
• Ballet flats: extremely shallow with no depth for an orthotic device.
• Slip-on loafers: no adjustable fastening means you cannot secure the foot over the orthotic.

The following shoe types are your best starting points when shopping for orthotic-compatible footwear:

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

If you have found a shoe with a removable insole but it still does not feel right, work through these steps:

1. Remove the factory insole completely. Do not 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. Try loosening the lacing. Retie the shoe with a little more room across the instep, then tighten gradually.
4. Consider going up half a size. A slightly larger shoe can make a significant difference when accommodating 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 for shoes. If a shoe passes all five checks, it is 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 top of the factory insole raises your foot too high inside the shoe. This causes 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 the problem persists, 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 and less accommodating than trainers. See our guide to work shoes for orthotic wearers for specific options that combine a smart appearance with orthotic compatibility.

Will any UK shoe brand definitely work with orthotics?

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