Abstract
A fluid chamber (20) for a shoe may be formed using pressure channels (190) in a forming mold (100A), 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 disclosed.
