Abstract
Footwear uppers include a footwear upper base having an instep region; one or more lace-engaging components located at a first side of the instep region; and one or more lace-engaging components located at a second side of the instep region. A bladder at the instep region includes: (i) a tongue and/or instep chamber, (ii) a first sealed seam region extending along a first side edge of the bladder, and (iii) a second sealed seam region extending along a second side edge of the bladder. The tongue and/or instep chamber extends between the sealed seam regions. A lace may apply a force to the tongue and/or instep chamber of the bladder. This force may move fluid from the tongue and/or instep chamber to a heel and/or ankle support chamber of the bladder. The lace may extend through a lace-engaging opening provided in a seam of the bladder.
