An article of footwear, such as a shoe, includes an upper and a sole. The upper may be formed with an outer layer and a floating textile layer relative to one or more portions of the outer layer. The floating textile layer has an apparent elongation that is less than an apparent elongation of the outer layer in response to an equal tensile force applied to each of the floating textile layer and the outer layer along a same axis of orientation. The differential in apparent elongation of the outer layer and the floating textile layer may increase wearability and functionability of the upper.

A shoe system includes a sole and a shoe upper connected with the sole. A gap is disposed between a first upper portion and a second upper portion. The shoe system also includes a first permanent connector permanently connected to the first upper portion; a second permanent connector permanently connected to the second upper portion, and a removable and printable connector strap connectable with the shoe upper. First and second releasable connector portions of the removable and printable connector strap are releasably connectable with the first and second permanent connectors, respectively.

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.

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.

Disclosed are a vamp construction and a method of vamp construction utilizing multiple layers in a multi-part vamp. This construction provides increased flexibility and comfort, more efficient material utilization, and aesthetic appeal. More specifically, the vamp includes a layer of vamp material, a layer of fabric, and a layer of elastic material.

An article of sports footwear that changes shape in two ways. Firstly, a change of shape occurs when such footwear is used to kick a ball with the toes. This change of shape maximizes the area of contact with a ball that is kicked with the toes. Secondly, a change of shape occurs when the article of sports footwear bends during running. This change of shape shortens the entire length of the article of sports footwear in order to prevent tripping. A flexible toe cap encases the foot and parts of a traditional article of footwear and attaches at or near the tarsometatarsal joint of a wearer.

Disclosed are devices, kits and methods for an enhanced pointe shoe for ballet. In some embodiments, an enhanced pointe shoe includes light-emitting diodes (LEDs) and sensors that may activate the LEDs based on the ballet performers movements. For example, the sensor may be a pressure sensor that activates the LEDs when a ballet dancer stands en pointe. In other embodiments, a kit that includes a power source, LEDs, one or more sensors, a toggle switch and connecting wires may be used to enhance a pointe shoe. In yet other embodiments, a ballet pointe shoe cover, which for example, may be made from spandex, and that includes the power source, LEDs and sensors may be used to enhance a pointe shoe for ballet performances.

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 may be utilized to form the textile element.

An article of footwear including a tensioning system is disclosed. The tensioning system is adjustable and includes a first layer and a second layer that is moveable and extends over the first layer. The article can include elements that are capable of distributing tension over the article. The article may include a tensile element, guide elements, and one or more strap guides attached to an underside of the second layer.
