These 24 foot-types are subdivided into 6 groupings of 4, known as "quads."
Each Quad has its own very specific foot and gait characteristics.This poster illustrates the natural progression of these 24 foot types from the most cavus (upper left), to the most pronated (bottom right), as they would typically appear in relaxed calcaneal stance. The columns reflect rearfoot alignment relative to the floor, and the rows represent associated forefoot deformities.This poster comes with a detailed explanation outlining the chart format and explanation of use. The measurements of this poster are 24''x36'' and is laminated.
