摘要： Disclosed herein is footwear. The footwear includes a midsole, a shock absorbing means, and an outsole. The midsole has on an upper surface thereof an air passage. At least one insertion recess is provided in a lower surface of the midsole and communicates with the air passage. The shock absorbing means is made of an elastic material and movable up and down by flow of air present in the shock absorbing means. The upper end of the shock absorbing means is opened and secured to the insertion recess of the midsole, and the lower end of the shock absorbing means is closed and protrudes downwards. The outsole functions to secure the shock absorbing means to the midsole. The present invention provides footwear having a shock absorbing means having a simple structure and a superior shock absorbing function, thus having high durability.
