What is the name given to the top edge of the vamp of a shoe?

The correct term for the top edge of the vamp of a shoe is called the throat. The vamp is the portion of the shoe that covers the top of the foot and the throat refers specifically to the area where the vamp meets the opening of the shoe. This part is crucial since it affects both the fit and the style of the shoe. In various shoe designs, the throat can dramatically influence how the shoe conforms to the foot as well as its overall aesthetic appeal.

The other terms listed refer to different components of a shoe. The collar typically refers to the part around the ankle or opening of a boot or shoe that may offer additional support or cushioning. Lining refers to the material inside the shoe that provides comfort and protection to the foot. The upper encompasses all parts of the shoe that are above the sole and includes the vamp, but it does not specifically identify just the edge where the vamp meets the opening.
