SECTION V - GLOSSARY

ASSEMBLED SHOE

includes within its scope the upper and sole when they are secured together. In shoe making, the upper including various parts thereof, such as the vamp, toe tip, quarters, linings, etc., are assembled and secured. The thus assembled upper is generally conformed to shoe shape by a lasting operation and attached to a sole. When the upper and sole are attached the product is known as a shoe in the trade. It will be noted that this term includes within its scope, (1) partially completed shoes, (2) shoes having outsoles and heels which are ready for wear, and (3) shoes being worn by their wearers.
