Abstract
An improved structure of the sole of shoes suitable for use in sports or any casual wear is characterized in that the mid-sole is provided with resilient spherical bodies within recesses in the front portion and/or the heel portion of the sole, and that the hardness of the resilient bodies can be adjusted to enhance the elasticity of the soles of the shoes by virtue of the fact that the spherical bodies can be inflated and deflated or can be bodily replaced, thereby enabling the requisite shock absorbing effect to relieve impact stress during running and fatigue during long walking to be obtained.
