A foot pressure measurement insole comprises an insole surface contacting with a sole. Sensors for detecting pressure, at a plurality of detection positions (x0, y0), applied by a foot to the insole are arranged at the detection positions (x0, y0) on the surface of the insole. The foot pressure measurement insole is characterized in that the detection positions (x0, y0) at least include positions,corresponding to a first toe, a first metatarsal, a second metatarsal, third to fifth metatarsals and a heel, on the surface of the insole. The invention further relates to a foot pressure detectionmethod. Therefore, gaits of people can be detected intelligently, and analysis and advices can be further given.
