Foot type and location of area of peak pressure under the metatarsal heads were determined for 54 healthy adults between the ages of 21 and 39 years. Feet were classified as neutral, pronated, or supinated. Each subject walked barefoot over a pedobarograph, and the area of peak pressure was identified as being either medial, central, or lateral under the metatarsal heads. A Fisher's exact test determined that there was a significant relationship between the area of peak pressure and foot type. A post hoc λ asymmetric test showed that the relationship was very weak. Nearly half (49%) of the feet were classified as neutral, 36% were pronated, and 15% were supinated. Pressure patterns were as follows: 62% central, 26% medial, and 12% lateral. Other factors besides foot type influence the area of peak pressure under the metatarsal heads.
