## Abstract

An article of footwear includes an upper and a sole coupled to the upper. The article of footwear includes an inflation system. The inflation system includes an inflatable bladder, a pump in fluid communication with the bladder, and a control circuitry operatively linked to the pump. The pump adjusts the air pressure of the inflatable bladder. The control circuitry receives a command signal from a remote device, and upon receipt of the command signal, the control circuitry transmits an actuation signal to the pump to adjust the air pressure of the inflatable bladder.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The computer readable medium storing instructions of claim 1, wherein the reference air pressure level is inputted by a user.

### Claim 3 (depends on 1)

The computer readable medium storing instructions of claim 1, wherein the reference air pressure level is determined based on a type of activity inputted by a user, and the type of activity is selected from a group consisting of running, walking, jumping, and participating in an athletic event.

### Claim 4 (depends on 1)

The computer readable medium storing instructions of claim 1, wherein the reference air pressure level is determined by:
obtaining a plurality of air pressure measurements of the inflatable bladder associated with a period of time;
calculating a desired air pressure level for the bladder using the plurality of air pressure measurements associated with the period of time; and
setting the desired air pressure level as the reference air pressure level.

### Claim 5 (depends on 1)

The computer readable medium storing instructions of claim 1, wherein the method further comprises:
determining whether a wearer's foot is received in the article of footwear; and
actuating the pump disposed on the article of footwear to inflate the bladder when determining that a wearer's foot is received in the article of footwear.
