Trauma/Injury to the Foot
Numbness in leg, particularly toes, could be caused due to a fracture in the bone or a joint of the toes. Any trauma caused to the toes, due to some heavy object falling on it or if some surgery has been conducted on the toes, can irritate the nerves, causing numbness in the process. If any joint in the toe gets dislocated, it can make the toes numb too.
