Warts on feet are caused by HPV (human papillomavirus). In medical terms foot warts are also referred to as plantar warts. There's plenty of ways through which you may come into contact with the virus and develop a wart. Most common example is if you have a small cut on your feet and you're walking barefoot in a public place.

Plantar warts are generally not a serious health concern but they can cause discomfort in your day to day life. Since foot is your weight bearing area, having a wart over there can be more painful than having it on your fingers.
Most people develop immunity towards HPV as they age which is why plantar warts are more common in children and young adults. But if you're not careful, you may still end up coming in contact with the virus and developing a plantar wart. Which is why you should avoid walking barefoot especially in public locker rooms.
Plantar warts are also common in people who have an underlying condition that makes the immune system weaker. One of the examples is HIV/AIDS. The weaker the immune system is, the more the chances of HPV penetrating your skin and resulting into warts.
