A shoe may include sole portions that are interchangeable with one another. That is, one of the sole portions may be removed from the shoe and replaced by another one of the sole portions. The interchangeable sole portions may include a common set of features (e.g., structure, design, color, etc.). Alternatively, each of the interchangeable sole portions may include a unique features, such that features of the shoe may be modified by exchanging sole portions. |
