Provided is a self-fitting and automatically adjustable footwear wherein the shoe upper and/or shoe tongue have or are attached to a shape memory material (SMM). Upon stimulation, the SMM deforms and brings the footwear to self-assemble about a foot, which further brings two clasp members close to each other and facilitates the clasp thereof to form a self-assembled and closed footwear. The clasp members may be integrated with straps or shoelaces, and optionally SMM. The footwear may include a motor, a control unit, and sensors which enable a motor-actuated fine tensioning of the footwear. A push button to enable manual opening of the footwear may be affixed on the footwear or removably attached to multiple surfaces/locations. The entire assembly generates data transmittable to health care providers and other data trackers. The footwear may include a battery, which may be charged by placing the footwear on a charge dock station.

Footwear, including athletic footwear, opens very wide, e.g., by moving an ankle containing portion of a footwear upper laterally/sideways with respect to the sole structure or a base portion of the upper (e.g., rotate it to the lateral side). In effect, the ankle containing portion may move/rotate sideways with respect to the sole structure/base portion via a connecting member (e.g., moving akin to rotation on a hinge type structure) to open in somewhat of a clamshell fashion. The rear of the upper base portion in this open condition may appear somewhat as an open backed slipper or slide type shoe. These actions and features open the rear heel area of the upper wide and low to enable easy insertion of a foot into the interior chamber, generally from the rear of the footwear structure. One or more straps can be used to secure the upper to the foot.

A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. A capacitive sensor, such as disposed within or upon the sensor housing, can be configured to provide the foot presence indication. In an example, foot presence can be detected using time-varying characteristics of a signal from the capacitive sensor.

An article of footwear can include a ferromagnetic body disposed in the article, and a magnetometer to measure a strength or direction of a magnetic field that is influenced by a position of the ferromagnetic body. One of the ferromagnetic body and the magnetometer can be configured to move relative to the other one of the ferromagnetic body and the magnetometer, for example according to movement of a foot in the article. In an example, the ferromagnetic body is disposed in a compressible insole and the ferromagnetic body moves in response to compression or relaxation of the insole. The magnetometer can be disposed in a platform or sole portion of the article that is relatively stationary compared to the ferromagnetic body. Rate of change information about the magnetic field can be used to control article functions or to provide information about a foot strike or step rate.

A foot presence sensor system for an active article of footwear can include a sensor housing configured to be disposed at or in an insole of the article, and a controller circuit, disposed within the sensor housing, configured to trigger one or more automated functions of the footwear based on a foot presence indication. In an example, the sensor system includes a capacitive sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

In an example, the sensor system includes a capacitive or magnetic sensor configured to sense changes in a body's proximity to the sensor in footwear. Characteristics of the sensed proximity can be used to update an automated footwear function, such as an automatic lacing function, or can be used to determine a step count, foot strike force, a rate of travel, or other information about a foot or about the footwear.

Articles of footwear, including athletic footwear, include one or more of: (a) a sole structure; (b) an upper having lateral and medial side elements engaged with the sole structure, the upper made from a polymer matrix structure that extends through at least a heel region; (c) a size adjustment mechanism located at the heel region; (d) a heel tongue element located adjacent the size adjustment mechanism; (e) a shoe securing mechanism; (f) an instep tongue member; and/or (g) a bootie member located at least partially within the foot-receiving chamber. Methods of manufacturing such articles of footwear also are disclosed.

A lacing system for tightening an article includes a first guide that is coupled with the article and positioned within a first zone of the article and a second guide that is coupled with the article and positioned within a second zone of the article with at least a portion of the second zone being different than the first zone. A first tension member is guided by the first guide within the first zone and a second tension member is guided by the second guide within the second zone. Tensioning of the first tension member or second tension member causes tightening of the respective zone of the article. A tensioning mechanism is also coupled with the article and with the first and second tension members. The tensioning mechanism is configured to tension the first and second tension members to tighten the first and second zones of the article.
