Abstract
A fluid chamber for a shoe may be formed using pressure channels in a forming mold, eliminating the need to insert a nozzle or needles into the chamber for inflation. A fluid chamber so formed may have a smaller seal area than a chamber formed using an inflation needle, making the chamber more visually pleasing. Apparatus and methods for forming a fluid chamber in this fashion are also disclosed.
