There can be a few reasons why your toes may hurt when you walk. The most common culprit is a trampling injury (when somebody treads on your foot), which can cause inflammation and damage to the nerves in the feet and toes. Other causes of toe pain may include: ​
A fracture or sprain in one or more of the bones in the foot or ankle
Preexisting conditions, such as diabetes, multiple sclerosis, arthritis, or neuropathy, that affect nerve function
Infection, such as pediculosis (ringworm) orbal disease
Nerve damage from chemotherapy or radiation therapy
