Collapsible tunnel systems or segmented tubular structures may be printed on or otherwise attached to base layers on articles of apparel, articles of footwear, or other articles of manufacture. The collapsible tunnel systems have two or more tubular structures attached to the base layer, with tunnels extending through the tubular structures. A tensile strand may be laced through the tunnels in the tubular structure such that when tension is applied to the tensile strand, the tunnels may collapse into a structure with a continuous tunnel through two or more tubular structures. In some embodiments, two or more segmented tubular structures each have two spaced-apart tubular structures joined by a connecting portion, and a tensile strand extending through tunnels in the tubular structures.

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.

The present disclosure provides a string collecting device and an article having a string, wherein the string collecting device includes a rotating part and a string winding part configured to wind a string; the rotating part is provided with at least one movable part that is capable of moving; the movable part is configured to be engaged with the string winding part when the rotating part is rotated towards a string collecting direction, and wherein when the movable part is engaged with the string winding part, the three, namely, the rotating part, the movable part and the string winding part, are connected in synchronous rotation.

An article of footwear includes an upper having a tensioning element operable to move the upper between a tightened state and a loosened state. The tensioning element includes a first strand having (i) a first portion extending along a lateral side of an ankle opening of the upper to a first turn in the heel region, and (ii) a second portion extending from the first turn and along the lateral side of the ankle opening to a second end at an anterior end of the ankle opening. The tensioning element also includes a second strand having (i) a first portion extending along a medial side of the ankle opening to a second turn in the heel region, and (ii) a second portion extending from the second turn and along the medial side of the ankle opening to a fourth end at the anterior end of the ankle opening.

A sole structure for an article of footwear includes a chassis including a footbed having an interior surface and an outer surface formed on an opposite side from the interior surface, the interior surface defining one or more sockets. The sole structure also includes one or more haptic elements each having a bottom surface received within a respective one of the one or more sockets and a top surface protruding from the interior surface of the chassis, each of the one or more haptic elements having a different hardness than the footbed.

A spine for an article of footwear includes a base extending from a first end to a second end. The spine also includes a sidewall extending transversely from the base from the first end to the second end. The sidewall has a plurality of sidewall supports including a forefoot sidewall support at the first end, a heel sidewall support at the second end, and a mid-foot sidewall support disposed between the first end and the second end and defining a maximum height of the sidewall.

A tightening device for tightening an article includes an elongate panel that is positionable about the article. The elongate panel has a proximal end and a distal end. A tensioning mechanism is coupled with the proximal end of the elongate panel. The tightening device also includes a tension member that is operably coupled with the tensioning mechanism so that an operation of the tensioning mechanism adjusts a tension of the tension member. The tightening device further includes at least one guide member that is coupled with the elongate panel between the proximal end and the distal end. The tension member is operable with the at least one guide member so that the tension member is routed about the article and along a portion of the elongate panel.
