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 lacing system for an article of footwear has a forefoot region, a midfoot region, and a heel region. The system includes a sole structure, an upper attached to the sole structure, the upper having a lateral side, a medial side, and a tongue, a housing that is disposed along the tongue and entirely within the midfoot region, and an electronics assembly enclosed entirely within the housing. The electronics assembly includes at least a motor and a gear assembly. A first lace extends from the housing through a first aperture and a second aperture, and the first lace is drawn into the housing when the motor is activated by a user.

An article of footwear includes an upper defining an opening for receiving a foot of a wearer and a sole structure affixed to an under side of the upper. The upper has a throat opening provided between a medial side of the upper and a lateral side, and further includes a forward portion for receiving a forefoot of the foot, a rearward portion for receiving a heel of the foot, and an intermediate portion between the forward portion and the rearward portion. The intermediate portion comprises a reactive material extending between the sole structure and the throat opening on both the medial side and on the lateral side of the upper. The reactive material has a negative Poisson's ratio and is bounded on either side by materials that have a positive Poisson's ratio.

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 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.

A shoe is provided with a first forming portion provided on a medial side and a second forming portion provided on a lateral side across a central opening formed forward from a foot insertion portion of an upper on each of which a string passing portion is formed; a first support member a tip end of which is fixed to the second forming portion, including a first string passing structure provided at the tip end, and extending downward so as to abut a medial side of a foot; a second support member a tip end of which is fixed to the first forming portion, including a second string passing structure provided at the tip end, and extending downward so as to abut a lateral side of the foot; and a shoelace which passes through the string passing portion and continuously passes through the first and second string passing structures.

A lacing system of an article includes two laces that are routed through the article of footwear to provide two distinct fastening zones. A first lace can be routed through a first set of lace-receiving passages in a first fastening zone of a body of the article, and a second lace can be routed through a second fastening zone of the body. A method of lacing an article includes routing the first lace and the second lace through the lace-receiving passages of the respective zones.

A footwear assembly includes an upper, a lace cable, a plurality of lace guides and a tensioner. The tensioner includes a tensioning member secured to a side of the upper proximate a toe box and the lace cable, and a floating overlay attached to a side of the upper proximate a toe box and the lace cable. The tensioning members include an elastic member. The tensioning members can be configured to provide a stiff lockout zone and an elastic stretch zone.

Disclosed is a closure system used in combination in any of a variety of applications including clothing, for example as a footwear lacing system comprising a lace attached to a tightening mechanism. The lace extends through a series of guide members positioned along two opposing footwear closure portions. The lace and guides preferably have low friction surfaces to facilitate sliding of the lace along the guide members so that the lace evenly distributes tension across the footwear member. The tightening mechanism allows incremental adjustment of the tension of the lace. The closure system allows a user to quickly loosen the lace and inhibits unintentional and/or accidental loosing of the lace.

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.

An article of footwear comprising a side lacing pattern features laces ending on the same side of the footwear with both lace ends exiting from the side of an intermediate row of the footwear. The lace travels in a single pass between the upper and lower rows of eyelets, beneath the outer surface of the upper such that the lacing uses each eyelet once without overlapping, using right angle turns at each eyelet within the lacing pattern.
