Are Flat Shoes Always the Healthiest Choice?

Are flat shoes always the healthiest choice? Not automatically. “Flat” describes one feature, not the whole fit. The American Academy of Orthopaedic Surgeons (AAOS) advises checking heel security and toe room even in lower-heeled shoes, rather than judging a pair by heel height alone (AAOS shoe-fit guidance).

The useful takeaway is not to trade one absolute rule for another. A flat shoe is not automatically wrong, and a small heel is not automatically right. Look at the complete shoe and how it feels during the activities you plan to do.

Lower heels do not make every shoe equivalent

There are good reasons to be cautious about high heels. AAOS explains that increasing heel height increases pressure beneath the ball of the foot, while a pointed toe adds further forefoot pressure (AAOS guidance on heels).

But choosing the lowest heel does not finish the comparison. Guy’s and St Thomas’ NHS Foundation Trust advises limiting heel height to under 4 cm, about 1.5 inches, and notes that a wider heel is more stable (NHS footwear guidance). That is general guidance, not a prescription for one exact heel height for every reader.

For example, a low shoe with a crowded toe box still deserves another look. A shoe with a small, broad heel also needs to fit comfortably and stay securely on your foot.

Compare more than the side profile

Use these checks when comparing flats with low-heeled styles. They draw on AAOS and NHS advice about toe space, secure uppers, and fastening:

• Look at the front: Check for enough width and depth for your toes, not just spare length beyond them.
• Check heel hold: Notice whether your heel repeatedly slips as you walk. Do not ignore movement simply because the shoe looks sensible.
• Try the fastening: Adjust available laces or straps so the shoe feels secure without uncomfortable pressure across the top.
• Walk in both shoes: Use your usual socks or hosiery and compare the whole fit, rather than deciding from a seated try-on.

The NHS guide emphasizes that the shoe should hold on to you, rather than you having to hold on to it. Our article on initial comfort and proper support offers another way to assess the whole shoe.

Changing from years of high heels?

A sudden switch to completely flat shoes may not feel comfortable for everyone. Guy’s and St Thomas’ notes that long-term high-heel use can shorten calf muscles and recommends asking a podiatrist for advice when changing from years in heels to flats (NHS advice on changing heel height).

That is a reason to seek individual guidance, not to push through discomfort or prescribe yourself a stretching routine. Persistent pain, numbness, swelling, or a wound should be assessed by a qualified clinician rather than addressed through shoe shopping alone.

The takeaway

Choose the complete fit, not just the flattest-looking sole. If you would like help comparing options, visit Disibio Shoes for one-on-one fitting help and bring the socks you plan to wear.
