The outer perimeter bond may be shaped such that the interior chamber forms: (i) a foot support chamber portion for supporting at least a portion of a plantar surface of a wearer's foot, and at least one of items (ii) and (iii) below, in which: item (ii) comprises a first side chamber portion (e.g., forming at least part of a first securing strap or a first footwear upper component), and item (iii) comprises a second side chamber portion (e.g., forming at least part of a first strap-engaging member or a second footwear upper component).
