A heel breast is the vertical part of a heel on a shoe, located directly beneath the arch. It's the portion of the heel that extends from the shoe's sole, supporting the wearer's weight. Think of it as the part of the heel that's directly under your arch when you're wearing the shoe.
Several sources confirm this definition:
- Dictionary.com: Defines heel breast as "the forward side of the heel, adjoining the shank of a shoe." https://www.dictionary.com/browse/heel-breast
- Footwear News: Describes the heel breast as "the vertical part of a heel located under the arch of the shoe. Often, this portion of the shoe is a continuation of the sole." https://footwearnews.com/shop/shoes-guide/anatomy-of-high-heels-1203232986/
The term "heel breast" is primarily used within the context of shoemaking and design. It's a specific anatomical part of a shoe's heel, not related to the human breast.
