Automatic inflation pump bladder system

A computer readable medium storing instructions for executing a method performed by a processor, the method comprising:

• obtaining a first air pressure measurement of an inflatable bladder disposed on an article of footwear;
• calculating a pressure differential between the first air pressure measurement of the bladder and a reference air pressure level;
• determining whether the calculated pressure differential is within a predetermined tolerance of the reference air pressure level;
• calculating an air pressure adjustment for the bladder based on the calculated pressure differential;
• and
• actuating a pump disposed on the article of footwear to adjust the air pressure of the bladder based on the calculated air pressure adjustment.
