What should I do if the thick cocoon on the sole still hurts?

Wearing high heels for a long time is due to uneven stress on the soles of the feet. After soaking your feet in warm water, exfoliate them with a millstone. If the calluses are thick, gently remove them with a knife, apply vaseline or Baique Ling and Meijiajing moisturizer, put on thick socks, and regularly remove the aged cutin on the feet. If necessary, you can buy some foot film to apply.
