How to Replace Hoka Insoles with Custom Orthotics

Why replace the stock insole?

Hoka sneakers are known for their plush cushioning and rockered sole, but the stock sock liner is a thin piece of foam, not a medical device. If you use custom orthotics to address overpronation, high arches, or other foot issues, the orthotic should sit directly under your foot. Replacing the liner lets the orthotic do its job without interference.

The American Academy of Orthopaedic Surgeons (AAOS) is a professional organization for orthopaedic surgeons, and OrthoInfo is its patient education site. These resources often recommend consulting a specialist before buying orthotics. A professional can tell you whether a Hoka model is suitable for your orthotic and how to fit it.

Check if your Hoka has a removable liner

Before you buy an orthotic, confirm that your Hoka's sock liner is actually removable. Most Hoka models, especially running shoes like the Clifton and Bondi, ship with a thin liner that is not glued down. You should be able to lift the heel edge with a fingernail. If you meet resistance, do not force it; you may damage the shoe or the liner.

If the liner is glued, you can still use an orthotic by placing it on top, but the added height may change the fit. To learn the difference between a sock liner and an insole, see sock liners vs insoles and our guide to removable insoles.

How to remove the stock insole

Start at the heel. Gently lift the liner with your fingers and peel it toward the toe. Work slowly, especially around the arch where it often curves around the midsole. If the liner tears, that is usually because you pulled too fast; do not use a sharp tool.

Once the liner is out, place it on a flat surface. It will serve as a template to compare against your orthotic. Keep the pair together so you can switch back if needed. Check the size marking on the liner if there is one; it tells you the internal size, which is useful when choosing an orthotic.

Fit the custom orthotic into the shoe

Place the orthotic on top of the stock liner. The outlines should match closely. The orthotic should sit flat, without curling up the sides of the shoe. If it is wider or longer than the footbed, you may need to trim it, but only if the orthotic manufacturer allows it. Many custom orthotics already match your foot shape and need no cutting.

Drop the orthotic into the empty shoe. Press the heel down first, then smooth the rest forward. Lace the shoe normally and walk a few steps. You should feel no heel slip and no pressure at the arch that causes pain. For more on how a shoe should fit with an orthotic, read how sneakers should fit.

Trimming and adjusting the orthotic

If your orthotic comes with trim lines, follow the instructions from the maker or your provider. Trim small amounts at a time and test often. Never trim a rigid orthotic that is not meant to be cut. If you are unsure, ask the professional who prescribed it.

A thick orthotic can change the stack height and the angle of your ankle. This may feel odd at first. Give yourself a short break-in period on soft surfaces. If you feel the orthotic sliding, your shoe may be too big or the orthotic may be too wide. See our guide to insole thickness and removability and sneaker insole arch height.

Troubleshooting common fit issues

If your foot slides forward while walking, your heel is slipping or the orthotic is lifting your heel too much. Try a heel-lock lacing pattern. We cover that in sneaker lacing techniques. If the orthotic causes a hot spot under the arch, the arch height may be too high for the shoe. Check the volume of the shoe and consider a lower-profile orthotic.

If the orthotic causes the toe box to feel cramped, the shoe may be too narrow or too short for the orthotic. Consider a wider model or a size up. The best Hoka sneakers guide can help you compare models that have more room.

Caring for the original liner and the orthotic

Keep the stock liner in a dry place. It can be swapped back in when you don't need the orthotic. Replace the liner when it shows signs of compression, like a flattened heel pad or visible creases. Orthotics also wear; follow your provider's advice on how often to replace them.

If you stand on hard floors all day, consider the National Institute for Occupational Safety and Health (NIOSH), a research agency focused on worker safety and health. Their resources on foot comfort and injury prevention may help you decide what cushioning you need.

What to pick for your use

Questions

Can I use my custom orthotic in any Hoka model?

Most Hoka running and walking shoes have a removable sock liner, but the internal volume varies. A thicker orthotic may not fit a narrow or low-volume model. Compare the shoe's stack height and width in the specs. When in doubt, ask the provider who fitted your orthotic.

Should I remove the stock insole before placing the orthotic?

In most cases, yes. Placing the orthotic directly on the midsole gives you a stable base and avoids adding excessive height. If the orthotic is very thin, you might be able to layer it, but that changes the fit and can cause heel slip.

How do I know if the orthotic is too thick?

After lacing the shoe, check that your heel does not slip when you walk and that the laces are not overly tight. If the top of your foot feels compressed, the orthotic is too thick for that shoe. Also, if your toes touch the end of the shoe, the volume is too low.

Can I trim a custom orthotic to fit?

Only if it is designed to be trimmed. Many custom orthotics come with trim lines or are already cut to your foot's shape. Never cut a rigid orthotic without the manufacturer's guidance. When in doubt, return to the professional who fitted you.

How long should a custom orthotic last?

It depends on the material and your activity level. A high-quality orthotic can last several years, but the cushioning may compress over time. Follow the provider's recommended replacement schedule, and replace it sooner if you notice a loss of support or visible wear.
