Crusties? I’m guessing infections here, either a fungus (athletes foot) or virus (varucas from the papilloma virus) or general wear and tear. The infections are picked up froim the environment – calssically varucas are associated with communal swimming pools. Both are easy to pick up but also easy to treat and very common
If you damage the tissue in your feet by wearing the wrong shoes then over time this can set up a reaction inside the foot which changes their shape. Women who wear high heels a lot tend to have these outgrowths because the body is trying to ptrotect itself from damage and stress.

Oh yuk, feet are disgusting!!
Crusty feet is often just hard dry skin which you can sort out with a pumice stone after a good soak in the bath!
Other foot problems are things like warts which are caused by the HPV virus that Tim mentioned. Something like 7-10% of the population are affected by this. But most people are simply immune to it. If your immune system is weakened you can end up getting really nasty warts as your body can’t fight the infection.
Corns are patches of hard skin that form over bony areas of the feet and are often caused by pointy shoes. If you get it on your big toe it’s called a bunion.
Yuk Yuk Yuk! 🙁
