Abstract
The present invention is an upper for an athletic shoe which substantially takes the form of an inflatable chamber. The upper is formed from first and second laminates which are welded together at various locations to form several fluid impervious chambers. The chambers, which are visible, are inflated with fluid to provide lightweight support and comfort to the foot of the wearer.
