An upper for an article of footwear includes a first material defining a void operable to selectively receive a foot. The first material includes an outer surface. The upper also includes a first edge at least partially circumscribing the void at an uppermost extremity of the upper and a second edge disposed at a lowermost extremity of the upper. The upper further includes a first biasing member (i) disposed at the outer surface of the upper, (ii) attached to the first material, and (iii) spaced apart from the first edge and the second edge. The first biasing member is operable to exert a biasing force on the first material to bias the first edge away from the second edge.

An upper for an article of footwear includes an inner boot having an ankle opening and an instep region formed between the ankle opening and an anterior end of the upper and a cushioning member disposed over the instep region of the inner boot and including a first side fixed to a medial side of the upper and a second side tethered to a lateral side of the upper.

An article of footwear includes an upper and a sole coupled to the upper. The article of footwear includes an inflation system. The inflation system includes an inflatable bladder, a pump in fluid communication with the bladder, and a control circuitry operatively linked to the pump. The pump adjusts the air pressure of the inflatable bladder. The control circuitry receives a command signal from a remote device, and upon receipt of the command signal, the control circuitry transmits an actuation signal to the pump to adjust the air pressure of the inflatable bladder.

Hot melt sequins and methods of applying these sequins are disclosed. A method of attaching two components includes stitching a hot melt sequin to one of the components and heating the hot melt sequin to bond the two components together. Sequins can also be applied to articles to create structural elements such as heel counters, toe covers, and lace cages. Sequins can be applied in 1D, 2D, and 3D patterns as well as in dispersive patterns. Sequins can be applied to vary the abrasion properties of a portion of an article.

Article of footwear include an upper and an insole that can be easily attach and detached from the upper. An article of footwear includes an upper, an insole, an outsole, and outsole retention fasteners. The upper includes flexible attachment straps. The insole is configured for removable coupling with the upper via the flexible attachment straps. The outsole is configured for removable coupling with the insole via the outsole retention fasteners.

A bladder for an article of footwear includes a first chamber having a first segment extending along a first side of the bladder and a second segment formed on an opposite side of the bladder from the first segment. The bladder further includes a second chamber at least partially surrounded by the first chamber and disposed between the first segment and the second segment. A manifold is in direct fluid communication with each of the first segment of the first chamber, the second segment of the first chamber, and the second chamber. A web area connects each of the first chamber, the second chamber, and the manifold. The bladder may include a first series of ports formed in the first segment of the first chamber and a second series of ports formed in the second segment of the first chamber.

An article of footwear may include an upper with an outer layer, an inner layer, and a chamber element positioned at least partially between the outer layer and the upper layer. The chamber element may be formed of two layers of a transparent colored polymer material and may be sealed to enclose a fluid. The chamber element may also have a plurality of subchambers. The outer layer may have a plurality of apertures. Each subchamber may protrude at least partially through a corresponding one of the apertures.

A cushioning element for an article of footwear includes a bladder having a first barrier layer and a second barrier layer joined together along a seam to define a chamber and a support element disposed within the chamber and having a support member and a plurality of flexible support legs each extending from a first end attached to the support member to a second end disposed between the first barrier layer and the second barrier layer within the seam.

Bladders for footwear uppers, footwear uppers including the bladders, articles of footwear including the bladders, and/or methods of making and using such bladders are described. At least one bladder chamber is provided in the instep and/or tongue area of the upper/article of footwear. In some examples, force applied to the instep based bladder chamber(s) moves fluid to one or more additional bladder chambers located in the arch and/or midfoot areas of the upper/article of footwear, and/or other areas of the wearer's foot. This movement of fluid increases fluid pressure and/or volume in the arch, midfoot, and/or other areas of the wearer's foot to provide additional support.

A dynamic pressure controlling footwear is disclosed and includes a main body, a control box and plural dynamic pressure controlling components. The main body includes a vamp disposed on an airbag. The control box includes a microprocessor and is disposed on a top surface region of the vamp. Each dynamic pressure controlling component is positioned on the airbag and includes an actuating pump and a pressure sensor packaged on a substrate by a semiconductor process. The substrate is positioned on the airbag and electrically connected to the microprocessor of the control box through a conductor. The actuating pump is in fluid communication with the airbag for inflating the airbag. The pressure sensor detects an inner pressure of the airbag to generate a pressure information. The microprocessor enables or disables the actuating pump according to the pressure information, so that the inner pressure of the airbag is adjusted.
