Abstract
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.
