Ashley is a runner who's suffering with a painful corn between toes 4 and 5. And it's infected! He's wondering what more he could do to stop it.
What causes callouses and corns on feet? Callouses are large in surface area but shallow. Corns are small but deep and more likely to be painful.
This pinch callous turned into a blister, in spite of taping. This is common. Taping is not the best option. Then, because it was weakened, this happened!
Some people swear callouses keep them blister-free and build them with pride. Others get them shaved off. So, do callouses protect against blisters?
