An article of footwear can include provisions for facilitating the installation of various components. During manufacture of the article of footwear, the upper and/or sole structure can include one or more specialized compartments designed to receive the components. The components can be installed in compartments after manufacture of the article of footwear. In some cases, the components can be used to perform different functions in a motorized tensioning system.

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 sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

Describes are support elements for a sole of a shoe, in particular a sports shoe, a sole and a shoe with such a support element, as well as a method for the manufacture of a support element. As examples, the support element includes a first partial member formed of a first material, and a second partial member formed of a second material. The first partial member is mechanically joined to the second partial member in a connection region, wherein the connection region is configured to allow the first partial member to rotate or slide relative to the second partial member. The first partial member, the second partial member, and the connection region can be co-molded and joined together in a single fabricating step.

In one possible embodiment, the inventive subject matter is directed to a foot covering, comprising: a thin, flexible compartment for receiving a foot. The compartment has a forefoot section, a midfoot section, and a rearfoot section of selected rigidity. The compartment has a top surface for securing the foot and a ground-facing surface having a sole divided into at least two portions comprising (1) a forefoot portion and midfoot portion and/or (2) a midfoot portion and a rearfoot portion. At least one sole portion comprises a midfoot portion disposed between a forefoot portion and/or a rearfoot portion. In the foot covering, each pair of sole portions is divided along a flexural line running generally transverse to the longitudinal axis of the foot. The sole portions and flexural line(s), in combination with the flexible compartment, have a material construction and are arranged so as to facilitate the close conforming of the foot covering to the foot of an intended user through plantar flexion to dorsiflexion.

Insole or shoe sole, which has a sensor device (10) having a plurality of sensor fields (1-9) for pressure detection and an electronic unit (15) that is electrically connected to the sensor fields (1-9) and has electronic components (17), wherein the sensor device (10) is formed in the manner of a sandwich with a middle layer (12) made of a piezoresistive material, a top layer (13) arranged above the middle layer (12) and a bottom layer (11) arranged underneath the middle layer (12). The top and bottom layer (13, 11) each include an electrically conductive material (14) in the region (1a-9a; 1b-9b) of a respective sensor field (1-9). The top and bottom layer (13, 11) each have a protruding flexible tab (23, 22) having conductor tracks (24-26) for electrically connecting the sensor fields (1-9) to the electronic unit (15). The electronic unit (15) has contact regions (29), against which the tabs (23, 22) bear by way of their conductor tracks (24-26).

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 sensor configured to sense changes in a capacitance signal in response to proximity of a body. A dielectric member can be provided between the capacitive sensor and the body to enhance an output signal from the sensor.

In one aspect of the present disclosure, a knitted component may include a knitted layer at least partially formed with a plurality of first yarns and a retention system formed in the knitted layer. The retention system may include a plurality of floating portions of the first yarns, and may be movable from a first state to a second state. In the first state, the plurality of floating portions of the first yarns may assume a slack state, where a float length of the first yarns may be greater than a dimension of the retention system.

Shoes and/or shoe elements facilitate natural foot motion and/or reduce forces tending to fight natural foot motion. In at least some such structures, a wearer's heel is secured to the hindfoot region of a shoe (e.g., by a strap system) in a manner that permits heel/forefoot rotation and that allows the lower leg to remain straight. In other structures, a shoe can include a heel supporting component that is separate from a midsole component, and this heel supporting component can move toward the lateral side and/or medial side of the shoe along an interface between the heel supporting component and the midsole component. Other suitable shoe and shoe component structures also are described.

A system, recharge apparatus, and method includes transmit coils positioned in a pattern to allow at least one of the transmit coils to establish a wireless link with a receive coil positioned in proximity of the recharge apparatus. A power source is coupled to the transmit coils and configured to selectively energize ones of the transmit coils to transfer power to the receive coil. An energy efficiency detection circuit is configured to detect an electrical response of each one of the transmit coils when energized by the power source, the electrical response indicative of an energy efficiency between the one of the transmit coils and the receive coil. The power source selectively energizes ones of the transmit coils, selected according to a statistical analysis of an historical record and the electrical response indicative of the energy efficiency meeting a minimum efficiency criterion for energy transfer to the receive coil.

A stalk sock can provide improved stealth by reducing foot impact noises and the like. The stalk sock can cover a foot, with or without a boot or other shoe, and can include a leg covering and a foot covering portion that extends from the leg covering. The stalk sock can be worn over a pant leg or it can be integrated with a pant leg.
