A method and apparatus for the diagnosis of abnormalities in the plantar surface of the foot employs an insole fabricated of a bottom layer of cushioning material, such as open or closed-cell foam, and a top, foot-engaging layer including a film embedded with thermochromic liquid crystals. The insoles are sized for a particular patient and inserted within his or her article of footwear. The patient then steps bare foot into the shoe and ambulates with the plantar surface of the foot in contact with the foot-engaging layer of film of the insoles for a sufficient period of time to obtain a thermographic reading on the top surface of the insole. The patient's feet are removed from the shoes, and the insoles themselves are then removed for examination and photographing of the pattern of infrared emissions produced.
