ABSTRACT:
A foot-support element such as an insole or a part of an insole is provided with a checkvalve through which it can be selectively inflated, the top and bottom walls of the insole being bridged by partitions which retain the shape upon pressurization. The insole is formed with upper and lower parts in upper and lower die members working together with an intermediate die member which, upon removal, allows the upper and lower die members to be brought together to fuse the parts of the insole together.
