Quick Fix: Stop the “hard plate” feel

  1. Remove the shoe’s insole to create space.
  2. Place the AFO on the shoe’s midsole (inside the shoe).
  3. Add a thin comfort insole (e.g., Dr. Scholl’s) above the AFO so your foot rests on the insert—not on carbon/metal.

This simple change eliminates direct contact and reduces most underfoot discomfort.

Dial in Fit & Position

  • Snug, not tight: You should slide one finger between brace and leg at mid-calf.
  • Heel fully seated: Center the brace and make sure your heel sits all the way into the heel cup.
  • Recheck after changes: Swelling or weight change can alter fit—adjust or see a clinician.

Size Range & When to Trim

Many AFOs are sold in size ranges (S/M/L/XL). Example: a Medium may cover up to a men’s size 12. If you’re a size 10, the footplate might run long/bulky and not fit your shoe well.

  • Option 1: Choose the next smaller size range if it still meets your support needs.
  • Option 2: Have a professional trim the footplate (orthotist/clinic) for a perfect shoe fit.

Socks, Liners & Padding

  • Use thin, seamless, moisture-wicking socks (avoid cotton), smoothed with no wrinkles.
  • Interface liners reduce friction and wick sweat for longer wear.
  • Spot-pad pressure areas with thin foam/gel; start minimal to avoid new hot spots.

Shoes That Work with AFOs

  • Removable insoles (essential) + deep toe box + firm heel counter.
  • Adjustable closures (laces/straps) to fine-tune volume.
  • Often 1–2 sizes larger is needed once the AFO is inside.
  • Avoid narrow slip-ons or high heels.

Heat, Moisture & Break-In

  • Wash/dry skin before wear; consider antiperspirant per provider advice.
  • Air the brace during the day if possible; always remove at night.
  • Clean with mild soap/water; dry fully to prevent skin issues.
  • Break-in: start 1–2 hours/day, add time gradually; most adjust in 2–4 weeks.

Maintenance & Skin Care

  • Inspect edges/straps for wear; replace worn parts promptly.
  • Moisturize skin at night (not right before wear) to avoid slippage.
  • Stop use and contact a clinician for persistent redness, blisters, numbness, or swelling.

Frequently Asked Questions

How do I stop the AFO from feeling hard under my foot?

Remove the shoe’s insole, place the AFO inside on the midsole, then add a thin comfort insert above the AFO. Your foot rests on the insert instead of carbon/metal.

Do I need bigger shoes for an AFO?

Usually yes — 1–2 sizes larger with a removable insole, deep toe box, and adjustable closures.

My size 10 foot doesn’t fit a Medium AFO. What now?

Either choose the next smaller size range (if support needs allow) or have a clinician trim the footplate for a proper shoe fit.

What socks are best?

Thin, seamless, moisture-wicking socks (avoid cotton). Smooth out wrinkles before donning.

How long is the break-in period?

Start with 1–2 hours/day and increase gradually; most users adjust in 2–4 weeks. Persistent pain or redness means stop and call a clinician.
