Foot Doctor is an education career simulation game similar to the popular Nail Doctor game. It teaches children and youths about conditions of the foot and the treatments used by family doctors, internal medicine physicians, podiatrists, orthopedic surgeons, and urgent-care and emergency room staff.
The player starts by selecting a patient. The game provides a diverse range of patients and even fictional celebrities at the end of the patient list. No matter the selected patient, each one typically has the same problems with their foot. The player must treat inflamed skin, boils or heat blisters, embedded objects and cuts on the sole of the patient's foot. They must also deal with scrapes or open wounds, a large mole and even one or more tattoos on the top of the foot. Lastly, they must correct the uneven edges, cracks and disease impacting the toenails.
In the role of a doctor or other medically trained professional, the player uses a wide range of tools to alleviate the patient's pain and help the healing process. Their basic toolkit includes tweezers, ice cubes, a cauterization device, first-aid antibiotic cream, plasters, and bandages. When dealing with a toenail problem, they also use clippers, cotton balls soaked in medicine, and a nail buffing tool. When the player successfully uses a tool, a burst of light appears on the foot, and then a green checkmark appears atop the foot once they place it back on the tray.
