ABSTRACT:
Apparatus for lasting of shoes has an elastic and flexible pad disposable in a cavity provided in a suitable housing. A portion of the pad is relieved for conforming to the configuration of a shoe last suspended in the housing cavity. Proper relieving of the pad permits same to stretch nonuniformly to conform to the irregular configuration of the last when a substantially uniform fluid pressure is applied to the pad, and this conforming of the pad to the last forces an upper arranged between the pad and last to be wiped over edges of the last and into contact with an insole disposed on the last for facilitating the securing of the upper to the insole.
