When to replace nursing shoes: signs the foam is gone

When should you replace nursing shoes? Sooner than they look. The upper rarely gives up first. The foam inside does.

The one-minute check

1. Press your thumb into the midsole. If it feels hard or does not spring back, the cushion is done.
2. Put the shoes on a flat table and look from behind. If they lean to one side, the heel has worn unevenly.
3. Look at the tread. Smooth patches mean less grip on wet floors.
4. Ask your feet. If your arches or heels ache earlier in the shift than they did a few months ago, that is the signal.

Two of those four, and it is time.

Why the shoe dies before it looks old

Foam compresses with every step and does not fully recover. Over months it gets thinner under the heel and the ball of the foot. The shoe still looks clean because you wipe it. Looking good is not the same as working well.

The exception

If you rotate two pairs, each pair may last longer because the foam gets a day to recover. Some people also use replacement insoles to get a few more weeks. That only works if the outer shoe is still sound and the tread is good. A smooth sole needs a new shoe, not a new insole.

Pain is not a shoe problem

If your pain is sharp, one-sided, or does not ease after a rest day, see a podiatrist or your doctor. Do not keep buying shoes in the hope that one fixes it.

End of shift

• First to go: the foam under the heel.
• Friday check: stand the shoes on a table and look from behind.
• Write the date you started wearing a pair on the inside tongue with a marker. It stops the guessing.
