What is a shoe "Pull Over" This is not a shoe?!

What is a shoe "Pull Over" https://shoemakersacademy.com/glossary/pullover Pullover A prototype sample shoe upper for checking pattern and fit. When a shoe is made, the first thing you will see is a pullover with no outsole and usually without logos or art. The pullover will not be made with color-correct materials, it will be made with an overstock color. During the development process, you may make several pullovers to get the pattern correct. You will also see pullovers made of each size during the pre-production phase. The pullover will also be sent to the outsole factory to ensure the shoe bottom will fit correctly.
