Claims20
A foot support system for an article of footwear, comprising:
- a compressor including a gas intake port and a gas outlet port;
- a first solenoid valve including a gas intake port, a first gas outlet port, and a second gas outlet port;
- a first fluid line connecting the gas outlet port of the compressor with the gas intake port of the first solenoid valve;
- a second solenoid valve including a gas intake port and a gas outlet port;
- a second fluid line connecting the first gas outlet port of the first solenoid valve with the gas intake port of the second solenoid valve;
- a third solenoid valve including a gas intake port and a. gas outlet port;
- a third fluid line connecting the second gas outlet port of the first solenoid valve with the gas intake port of the third solenoid valve;
- a first fluid-filled bladder configured to support at least a first portion of a plantar surface of a user's foot, wherein the first fluid-filled bladder includes a gas port;
- a fourth fluid line connecting the gas outlet port of the second solenoid valve with the gas port of the first fluid-filled bladder;
- a second fluid-filled bladder configured to support at least a second portion of a plantar surface of a user's foot, wherein the second fluid-filled bladder includes a gas port;
- and
- a fifth fluid line connecting the gas outlet port of the third solenoid valve with the gas port of the second fluid-filled bladder.
