Abstract
Disclosed is an air cushion having a support pin structure for absorbing shock, a method for manufacturing the air cushion, and footgear comprising the air cushion which does not exhibit any bulging effect, even upon application of an external pressure, to thereby improve the stability thereof. The air cushion includes: an upper plate having a plurality of support pins arranged at the same height or different height in a downward direction on the bottom surface thereof; a lower plate having a plurality of pin receiving bodies on the top surface thereof opposite to the upper plate, each of the pin receiving bodies having a groove into which each of the support pins is inserted; and a cushion body adapted to surround the coupled state of the upper plate with the lower plate where the support pins are received and fixed into the pin receiving bodies, thereby maintaining the air-tightness therein.
