Abstract

An article of footwear with a dynamic support system that controls arrays of tiles in the upper of the footwear to adjust the level of support provided in different regions of the upper. Sensors in the sole of the footwear, in the upper of the footwear and/or in an article worn by the wearer of the footwear measure the level of stress or other characteristics and provide input to one or more microprocessors that control motors located in the sole or in the upper of the footwear. When the motors are activated, they may compress or loosen arrays of tiles to adjust the stiffness of the upper in one or more regions of the upper.

First claim

a first array of tiles in a left upper of the left article of footwear, wherein the first array of tiles is mechanically connected to the first reel by a first cable system;
the right article of footwear comprising:
a second microprocessor;
a second pressure sensor in a right sole of the right article of footwear in communication with the second microprocessor;
a second reversible motor in communication with the second microprocessor;
a second reel attached to the second motor; and
a second array of tiles in a right upper of the right article of footwear, wherein the second array of tiles is mechanically connected to the second reel by a second cable system;
wherein the first microprocessor is configured to receive input from both the first pressure sensor and the second pressure sensor, and to respond to input received from the second pressure sensor by activating the first motor to compress the first array of tiles;
wherein the second microprocessor is configured to receive input from both the second pressure sensor and the first pressure sensor, and to respond to input received from the first pressure sensor by activating the second motor to compress the second array of tiles;
wherein the first array of tiles is an array of diamond-shaped tiles that is mechanically connected to the first reel by a first plurality of first cables traversing the tiles diagonally; and
wherein the second array of tiles is an array of diamond-shaped tiles that is mechanically connected to the second reel by a second plurality of second cables traversing the tiles diagonally.

2. The left article of footwear and the right article of footwear of claim 1 , wherein the first microprocessor and the second microprocessor are in wireless communication with each other.

3. The left article of footwear and the right article of footwear of claim 2 ,
wherein the second pressure sensor is in communication with the second microprocessor and wherein the first microprocessor receives data indicative of a level of pressure from the second pressure sensor via wireless communication with the second microprocessor, and
wherein the first pressure sensor is in communication with the first microprocessor and wherein the second microprocessor receives data indicative of a level of pressure from the first pressure sensor via wireless communication with the first microprocessor.

4. The left article of footwear and the right article of footwear of claim 1 , wherein the array of tiles is located in a forefoot region of a first upper of the first article, and the pressure sensor is located in a big toe region of the first upper.

5. The left article of footwear and the right article of footwear of claim 1 , wherein the left article includes an accelerometer sensor.

6. The left article of footwear and the right article of footwear of claim 5 , wherein the accelerometer sensor is in communication with the first microprocessor and wherein the second microprocessor receives data indicative of a level of acceleration from the accelerometer sensor via wireless communication with the first microprocessor.

a first reel attached to the first motor; and
a first array of tiles in a left upper of the left article of footwear, wherein the first array of tiles is mechanically connected to the first reel by a first cable system;
the right article of footwear comprising:
a second microprocessor;
a second pressure sensor in a right sole of the right article of footwear in communication with the second microprocessor;
a second reversible motor in communication with the second microprocessor;
a second reel attached to the second motor; and
a second array of tiles in a right upper of the right article of footwear, wherein the second array of tiles is mechanically connected to the second reel by a second cable system;
wherein the first microprocessor is configured to receive input from both the first pressure sensor and the second pressure sensor, and to respond to input received from the second pressure sensor by activating the first motor to compress the first array of tiles;
wherein the second microprocessor is configured to receive input from both the second pressure sensor and the first pressure sensor, and to respond to input received from the first pressure sensor by activating the second motor to compress the second array of tiles;
