The angle between the Heel Feather Plane and the Last Bottom Feather Line. It occurs forward of the Breast Line and corresponds to the Mid-Tarsal and Tarsal-Metatarsal Joints of the foot. The crank only occurs on high heeled lasts and accommodates the way the foot bends in front of the heel bone when the heel is raised where the toes remain flat on the ground. Some feet bend a lot and some hardly at all. To correspond with these variations, there are high cranked lasts, low cranked lasts and most commonly, mid-cranked lasts.
