Feiss line

[Henry Feiss, 20th-century U.S. orthopedic surgeon]
A line that extends from the first metatarsophalangeal joint, over the navicular tubercle, to the apex of the medial malleolus. Changes in the angle formed by this line before and during the application of weight can be used to determine excessive pronation of the foot. If the angle formed by the Feiss line is between 30° and 90° while the foot is bearing weight, the foot may be considered hyperpronated.
