Abstract: Footwear upper components include a fabric element and a bladder component that defines a sealed interior chamber. The bladder component includes: (a) a first major surface engaged with the fabric element, wherein this first major surface defines at least part of a first perimeter seam surface and at least part of a first surface of the sealed interior chamber, (b) a second major surface opposite the first major surface, wherein this second major surface defines at least part of a second perimeter seam surface opposite the first perimeter seam surface and at least part of a second surface of the sealed interior chamber opposite the sealed interior chamber's first surface, and (c) and a fluid chamber between the first and second major surfaces. The first major surface (and optionally the second major surface) may include texturing, e.g., texturing corresponding to texture present on a surface of the fabric element.

Abstract: Footwear upper components include a fabric element having a first thermoplastic polyurethane component and a bladder component that defines a sealed interior chamber for containing a fluid. The bladder component includes an outer perimeter seam that extends at least partially around the sealed interior chamber, and at least a portion of this outer perimeter seam is engaged with the first thermoplastic polyurethane component of the fabric element. The outer perimeter seam seals two thermoplastic sheets together to form the bladder component.

Abstract: Footwear with integrally knit uppers having features for increasing containment around a wearer's foot, improving strength and durability, and incorporating touch feedback through increased coefficient of friction while removing weight due to traditional additional components. The knitted component may be radially knitted so that courses converge towards a common area, like the throat region of the upper. Additionally, a fusible yarn may be knit on at least the exterior-facing surface of a containment area of the knitted component to create additional lock-down along lines of containment. Further, tensile elements may be incorporated within the containment area to provide strength and lock-down along desired lines of containment. Additionally, the fusible yarn may be a grip yarn that creates areas with greater coefficients of friction.
