  • a claw foot has a small ground contact area, so it easily feels fatigue, pain and inflammation may be generated on the sole of the foot or the toes and knee pain may be generated, and it easily gets sprained in comparison to other people. However, it is supported through wide supporting areas of the first coil spring 21 and the second coil spring 22, so this problem is remarkably reduced.
  • a normal foot compresses the first coil spring 21 first and then the second coil spring 22 is compressed with a short interval.

  • a flatfoot (see a profile F3) strongly compresses the first coil spring 21, the second coil spring 22, and the third coil spring 23. Since a flatfoot has a flatter profile, the distance (stroke) of compressing the arch spring module 20 is greatly increased and strong pressure is felt on an arch. A flatfoot feels chronic fatigued due to a large ground contact area, and the arch is fallen at the inside of the foot and the heel inclines outward, but the insole according to an embodiment of the present invention is used, strong pressure is applied to the arch of a flatfoot, and accordingly, a predetermined level of natural correction effect is achieved. In particular, a normal foot becomes a flatfoot due to aging in some cases, but there is an effect of delaying progression to a flatfoot or correcting a flatfoot due to aging.
