An article of footwear includes a fitting system with an upper member that is supported by the upper and a strand guide that is supported by the sole structure. The strand guide is flexible and flexes in concert with the sole structure. The strand guide has a guide surface. The fitting system further includes a tensioning system with a flexible strand that is configured to bias the upper member toward the strand guide. The flexible strand has a first section coupled to the upper member and a second section extending through the sole structure. The second section abuts the guide surface. The second section is configured to slide across the guide surface as a result of flexure of the strand guide. The first section and the upper member are configured to move relative to the sole structure as a result of sliding of the second section across the guide surface.

Provided are, among other things, shoes having elastic tongue-securing straps. In one representative embodiment, a shoe includes: (a) a sole; (b) an upper, extending above the sole, that includes a front section, a left side, a right side, a rear section, and a tongue that originates from the front section and extends rearwardly between the left side and the right side; (c) a left elastic strap that extends from a left side of the tongue and: (1) extends through a loop that is securely attached to the left side of the upper and has a distal end securely attached to the sole, and/or (2) has its distal end securely attached to the left side of the upper; and (d) a right elastic strap that extends from a right side of the tongue and: (1) extends through a loop that is securely attached to the right side of the upper and has a distal end securely attached to the sole, and/or (2) has its distal end securely attached to the right side of the upper, with the left elastic strap having a proximal end fixedly attached to the left side of the tongue and the right elastic strap having a proximal end fixedly attached to the right side of the tongue.

An article of footwear includes a front end, a rear end, a sole structure, an upper attached to the sole structure, and a strap system engaged with the upper. The upper defines a forefoot region, a midfoot region, and a heel region of the article of footwear, and the upper and the sole structure together define an interior cavity. The strap system comprises a strap configured to tighten portions of the upper within the heel region in response to the user's toe movement within the interior cavity.

An article of footwear includes an upper defining a throat configured to receive a foot. The article of footwear also includes a sole structure coupled to the upper. The article of footwear further includes a panel having a first side coupled to the upper for movement between an open position and a closed position. The panel exposes a portion of the throat in the open position and covers the portion of the throat in the closed position. The article of footwear also includes a strap having a first end and a second end opposite the first end. The first end and the second end are disposed on a first side of the upper with a body portion of the strap disposed between the first end and the second end surrounding the upper.

A material that includes at least one layer made of an auxetic structure and articles of footwear having soles comprising the materials. When the material is under tension, it expands in both the direction under tension and in the directional orthogonal to the direction under tension. The articles of footwear have soles that have at least one layer made of a material that has a pattern of apertures to provide the auxetic structure. The apertures are surrounded by sole portions that can rotate or pivot to change the size of the apertures.

An article of footwear includes a fitting system with an upper member that is supported by the upper and a strand guide that is supported by the sole structure. The strand guide is flexible and flexes in concert with the sole structure. The strand guide has a guide surface. The fitting system further includes a tensioning system with a flexible strand that is configured to bias the upper member toward the strand guide. The flexible strand has a first section coupled to the upper member and a second section extending through the sole structure. The second section abuts the guide surface. The second section is configured to slide across the guide surface as a result of flexure of the strand guide. The first section and the upper member are configured to move relative to the sole structure as a result of sliding of the second section across the guide surface.

A shoe fastening system designed to engage the eyelet holes of a shoe, comprising, an anchor, wherein the anchor has a first end and a second end, wherein the first end has means to detachably engage with an eyelet of a shoe and the second end has a connection means, an attachment member having a first end and a second end, wherein the first end is designed to securely fit within the connection means of the anchor and the second has a closed loop, a strap, wherein the strap is sized to fit through the closed loop of the attachment member and is a predetermined length and width, and a locking mechanism fitted to receive the strap and engage the strap to keep the strap at a specific length.

The elastic closure for footwear is a releasable closure for an open upper of an article of footwear. The elastic closure includes an elastomeric loop having opposed first and second ends, an anchoring member, such as a button, secured to the first end of the elastomeric loop, and an aglet secured to and covering the second end of the elastomeric loop. In use, the aglet and the second end of the elastomeric loop are inserted from above through a first eyelet of an upper of the article of footwear, so that the aglet and the second end of the elastomeric loop may be drawn through a second eyelet of the upper from below. The button prevents the first end of the elastomeric loop from passing through the first eyelet. The second end of the elastomeric loop is then stretched across the upper and releasably secured about the button.

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.

A tensile strand element for an article of footwear is disclosed. The tensile strand element includes one or more tensile strands secured at their endpoints between the sole and upper of an article of footwear, creating one or more looped portions. The unsecured looped portions may extend into the fastening region of the footwear and engage with a fastening system to tighten the footwear upper snugly against a wearer's foot to provide added support.
