An article of footwear has an upper including a body and a unitary support frame attached to the body. A sole structure may be attached to and underlie the upper. The unitary support frame may support the body over the sole structure, and the body may define a foot-receiving cavity over the sole structure and an ankle opening in communication with the foot-receiving cavity. The unitary support frame may define a medial peak at a medial side of the article of footwear and a lateral peak at a lateral side of the article of footwear and may extend forwardly and downwardly from the medial peak and the lateral peak.

Described are shoes having an upper, and at least one of an outer sole and a midsole connected to the upper, with at least one of the outer sole and the midsole formed of knitwear. A shoe includes an upper and a midsole coupled to the upper. The midsole includes a textile material that forms a plurality of hollow spaces. A particle foam is disposed in the plurality of hollow spaces.

An upper for an article of footwear is configured to be connected to a sole structure and is configured to receive a foot. The upper includes a knitted component having a strobel portion that is configured to be disposed underneath the foot. The strobel portion defines an interior surface and an exterior surface of the knitted component. The strobel portion defines a strobel passage between the interior surface and the exterior surface. Also, the upper includes a tensile strand that extends through the strobel passage.

An article of footwear includes a knitted upper component including a heel reinforcement area and monofilament in the heel reinforcement area. The article of footwear also includes a thermoplastic polyurethane yarn stitched into the knitted upper component. The thermoplastic polyurethane yarn is fused with the knitted upper component at the heel reinforcement area. The article of footwear may include at least one of an outer sole and a midsole connected to the upper, with at least one of the outer sole and the midsole formed of knitwear.

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.

An article of footwear may include an inner knit layer forming a void dimensioned for receipt of at least a portion of a foot, along with an outer knit layer, where the outer knit layer at least partially surrounds the inner knit layer. The outer knit layer may define window for viewing of the inner knit layer, the window being located at an overfoot portion of the article of footwear, and the window exposing a portion of the inner knit layer. The inner knit layer may be movable relative to the outer knit layer at the window.

In one aspect, the present disclosure provides an article formed of a knitted component. The article may be an upper for an article of footwear. The knitted component may have a first portion and a second portion, where the first portion of the knitted component at least partially forms a foot-receiving portion of the upper, where the second portion of the knitted component at least partially forms a strap of the upper, where the strap includes a first edge and a second edge secured to the first portion of the knitted component, and where the strap includes a third edge that extends from the first edge to the second edge.

An article of footwear with a dynamic support system that controls arrays of tiles in the upper of the footwear to adjust the level of support provided in different regions of the upper. Sensors in the sole of the footwear, in the upper of the footwear and/or in an article worn by the wearer of the footwear measure the level of stress or other characteristics and provide input to one or more microprocessors that control motors located in the sole or in the upper of the footwear. When the motors are activated, they may compress or loosen arrays of tiles to adjust the stiffness of the upper in one or more regions of the upper.

A warp knit element for an article of footwear includes a plurality of cell structures that extend from a sole structure to a lacing region of an upper.

A knitted component for an article of footwear may have an overfoot portion and an underfoot portion, a first yarn, where the first yarn at least partially forms the overfoot portion and at least partially forms the underfoot portion, and a second yarn, where the second yarn at least partially forms the overfoot portion and at least partially forms the underfoot portion. The first yarn may include a first material composition with a first melting point and the second yarn may include a second material composition with a second melting point. The first melting point may be at least 20 degrees Celsius higher than the second melting point.
