A variable ankle supporting shoe assembly includes a shoe including a perimeter wall having a lining comprising a foamed material. A magnetorheological fluid impregnates the foamed material and is alternated between a first state wherein the foamed material is bendable and a second state wherein the magnetorheological fluid forms a rigid structure within the foamed material such that the foamed material is not bendable. The lining forms a rigid and supportive shell when the magnetorheological fluid is in the second state. An actuating system alters the magnetorheological fluid from the first state to the second state when a condition has been met. The condition is met when the actuating system detects a combination of a threshold angle and a threshold pressure has been surpassed by the sole.

A shoe includes a sole, an upper, and a welt. The sole and upper define a seam. The welt overlies the seam. The sole includes flex grooves. The upper includes perforations. The welt includes flex slits.

An article of footwear is provided, which may include an upper and a sole structure. The upper may include an exposed outer layer forming at least a portion of an external surface of the upper. The upper may also include a polymer foam material selectively located on an inner side of the exposed outer layer and adjacent portions of the exposed outer layer, thereby forming padded portions of the upper. The padded portions of the upper may be located in areas of the article of footwear that correspond with predetermined bones of a foot of a wearer of the article of footwear.

The present invention concerns a shoe upper, including (a) a first sheet, (b) a second sheet, (c) a connecting region in which the first sheet is connected to the second sheet, and (d) a first coating. The first coating is applied onto a first region of the first sheet, a second region of the second sheet, and a third region of the connecting region. The first region, the second region, and the third region are connected.

The invention is a high heel shoe with an upper that will provide comfort and flexibility for the wearer. In a preferred embodiment the upper consists of two at least two materials: 1) a firm fabric, such as leather, that will hold the shape of the design and have limited flexibility; 2) a flat knitted elastic, such as knit elastic, which will not narrow, or not narrow significantly, when stretched. In addition, the firm fabric is configured to have a flex-point and in a preferred embodiment is formed of two pieces of the firm material having a split between them providing the desired flex-point.

An article of footwear and a method of manufacturing the article of footwear are disclosed. The footwear may include an upper and a sole structure. The upper incorporates a textile element with edges that are joined together to define at least a portion of a void for receiving a foot. The textile element may also have a first area and a second area with a unitary construction with varying stitch configurations. The upper may also incorporate longitudinal ribs extending along the lateral and/or medial sides of the upper. Various warp knitting or weft knitting processes, including circular knitting, may be utilized to form the textile element.

Aspects of the present disclosure provide a flexible, form-fitting, slide-type sandal, which includes a footbed and a strap affixed to the footbed on two sides. The strap comprises an underlay that spans the width of the footbed, as well as lateral and medial overlays with an expansion joint therebetween. The expansion joint between the lateral and medial overlays allows the underlay to flex and provide a better fit for the wearer.

An article of footwear may have an upper and a sole structure secured to the upper. The sole structure has a plurality of support elements, and each of the support elements include a shell and a core. The shell defines an interior void and is formed from a polymer material that extends around substantially all of the void. The core has a shape of the void and is located within the void, with at least a portion of the core being a polymer foam material. The polymer foam material of at least two of the support elements may have different densities.

Articles of footwear having an upper that includes a tensile support structure are described. The tensile support structure is formed by a plurality of strands that are arranged in a chain-linked configuration. The chain-linked arrangement of the strands assists with distributing tensile forces over portions of the upper of the article of footwear and helps to conforms the upper to a foot of a wearer upon the application of tension.

Described are shoes for ball sports including an upper having an outer surface. An actuator is configured to change at least one surface property of a portion of the outer surface of the upper, and a sensor is configured to be sensitive to movements of the shoe. A processing unit is connected to the actuator and the sensor and configured to process sensor data retrieved from the sensor and to cause the actuator to change the at least one surface property of the portion of the outer surface of the upper if a predetermined event is detected in the sensor data.
