What is the term for the front part of the heel of a shoe?

The term for the front part of the heel of a shoe is "heel breast." This terminology is specific to footwear design and construction. The heel breast is the area where the heel of the shoe meets the upper part, providing a defined shape and support. Understanding this term is essential for those involved in the design and manufacturing of shoes, as it helps in discussing various components of a shoe's structure and ensuring proper fit and comfort.

In contrast, heel cap refers to a protective covering for the heel, toe box refers to the front part of the shoe where toes are located, and the sole is the bottom part of the shoe that contacts the ground. Each of these terms relates to different parts of shoe construction but does not specifically address the front part of the heel, which is why "heel breast" is the accurate term in this case.
