The last design is based on the data of each part of the foot, from the Angle of shoe design, belonging to the first. The design of last shape directly affects the beauty and comfort of shoes.  

1. The foot has four bows, namely the front, rear transverse bow, inside and outside the bow. In the movement of the foot, the four bows play the role of spring, slowing the ground recoil. Design type if the ball when the protruding through here, in this here do shoes for a long time, will cause transverse ligament damage, bow before losing elasticity, make its subsidence, which in turn caused within cross bow, under the longitudinal arch collapse, forming flat foot. Flat feet are easy to cause patients to exercise and to stand for long periods of pain. In the design of the forehand, the design should be based on the foot. The former stilt is based on the natural stilt of the foot, and the height of the stilts of the adult is generally controlled at 15-18, which will lead to a large elevation of the forepaw. The higher the stilt, the smaller the front pallet, the smaller the front stilt, so that the floor area of the front palm can be guaranteed, so that the wearer will not be sprained.    

2. Plantar toe joint is under load is one of the main parts of the body weight and labor, is the key part of bent, when walking here plantar circumference size and the flesh is reasonable, will affect the service life of wearing comfort and shoes. The plantar is large and the foot moves in the shoe, also bad. The height of the last post is generally 20-40 old n.
