Preventing Problems with Used Shoes

Clean and disinfect second-hand shoes thoroughly, ideally with antifungal sprays.

Wear socks to reduce friction and moisture.

Break shoes in slowly.

Choose breathable materials and the correct size.

That yellow bump is your skin’s way of signaling too much friction. Fixing the shoe fit usually solves the problem quickly—and when foot issues persist, professional care can help you get back to comfortable, healthy steps.
