Abstract
The present invention provides an improved shoe structure to improve the sport efficiency and the wearing comfort of the user. The shoe structure comprises a base portion and a cover portion, wherein a plurality of flexible devices, such as springs, are formed within the base portion of the shoe structure to provide a load-bearing function. The shoe structure of the present invention is designed not only to provide comfort but also to bear a high load of weight such that the foot of the user can be protected by minimizing the impact force produced from the ground when the user steps or jumps on the ground. A plurality of air gaps are formed within the shoe structure to circulate the air within the shoe structure so that the foot of the user can keep dry and active in a clear environment.
