Abstract
An insole that functionally adjusts its supporting curvature according to the heel height is disclosed. A first supporting portion is disposed at the metatarsus. A second supporting portion is disposed between the front edge of the calcaneus and the back edge of the metatarsus. The bottom of the second supporting portion is formed with several grooves in the horizontal direction. The width of the grooves is inversely proportional to the heel height, thereby functionally adjusting the supporting curvature.
