The present disclosure discloses a cord tightening and loosening device, a shoe, a glove, a medical protective equipment and a storage device. The cord tightening and loosening device includes a rotary knob, a pawl disc, a base, a reel and a chassis. When the first meshing part is meshed with the second meshing part and the rotary knob rotates in a first clock direction, the rotary knob can drive the pawl disc to rotate, and then the pawl disc drives the reel to rotate, so that the cord tightening and loosening device can be in a tightening state and the cord can be wound around the winding part to tighten the cord.

An article of footwear may include an upper configured to receive a foot of a wearer, the upper including one or more elastic portions and one or more substantially inelastic portions. The footwear may further include a plurality of lace receiving members fixedly attached to an outer surface of the upper on the inelastic portions of the upper. Also, the footwear may include a sole structure fixedly attached to the upper. In addition, the footwear may include a motorized tensioning system including a motorized tightening device and a tensile member extending through the plurality of lace receiving members, the tightening device being configured to apply tension in the tensile member to adjust the size of an internal void defined by the article of footwear by drawing two or more of the plurality of lace receiving members closer to one another.

In a fastening structure, a third guide member located on the medial side and a third guide member located on the lateral side overlap each other in a foot length direction of footwear as viewed in the foot length direction. A tightening member is guided such that intermediate portions of the tightening member, which are located on the medial and lateral sides, extend in a direction including a component of the foot length direction without crossing each other in a foot width direction of the footwear.

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 or magnetic sensor configured to sense changes in a body's proximity to the sensor in footwear. Characteristics of the sensed proximity can be used to update an automated footwear function, such as an automatic lacing function, or can be used to determine a step count, foot strike force, a rate of travel, or other information about a foot or about the footwear.

An article of footwear including a sole, an upper joined with the sole, and a lacing system. The lacing system is configured to secure the footwear to the wearer's foot and includes a primary lace support, a secondary lace support, and a lace. The primary lace support has a plurality of primary loops disposed on an exterior surface of the upper. Portions of the secondary lace support are inserted through the primary loops to form a plurality of secondary loops. A lace extends through the plurality of secondary loops. The lace is slidably adjustable within the secondary loops and the secondary loops are slidably adjustable within the primary loops to adjust the fit of the article of footwear on a wearer's foot.

A closure system for a shoe includes a single shoelace which can be secured and tightened through the use of one hand. The shoe includes a button around which the shoelace is wrapped to facilitate easy removal of the shoe. In one embodiment one end of the shoelace is secured under the upper of the shoe near the toe and a second end of the shoelace is secured in a slider that is slidably mounted on the rear of the shoe to provide micro-adjustments of the tightness of the shoe. Alternatively, the shoe includes a strip of piping around the rear of the shoe and a slider in which the second end of the shoelace is secured slides along the piping when the user wants to make micro-adjustments. The adjustment of the tightness of the shoe can also be made by sliding a barrel that is located over the top of the tongue.

A shoe may include an upper and a sole structure. The upper may include a shell and first, second, third, and fourth sets of tensile restraints. Each of the sets may have one or more tensile restraints extending over and/or through a corresponding portion of the shell. The shell may be engaged with the sole structure and define an interior void configured to receive insertion of a user's foot. The first, second, third, and fourth sets of tensile restraints may be configured so that, upon securing of one or more structures to tighten the upper and connect the sets of tensile restraints, two linear axes of tension with anchors located in the forefoot and heel region extend diagonally across the article from one side to the other.
