You have a dress you can wear 100 ways to Sunday, so shouldn’t your footwear be just as versatile? The 4-in-1 Stack Shoe, which received a 2010 Red Dot Award for product design, offers its wearer four different options—boot, high-top, low-top, or mule—through a system of snap fasteners. But the real magic happens when two or more pairs come into play. Since the pieces are modular in nature, you’re free to mix and match different colors to create your own two-toned designs.
The shoe allows you to “stack” different heights of shaft on top of a base, which in turn can be worn as a slide.
A new construction based on buttons rather than zippers allows you to “stack” different heights of shaft on top of a base, which in turn can be worn unencumbered as a slide or mule. The addition of a quarter, the part of the shoe’s upper that covers the sides and back of the foot, results in a low-top running shoe. A thicker wedge turns it into a high-top, while a tall ankle support converts the 4-in-1 into a boot. Both the tongue and the shoelace are equally extendable (and interchangeable), making this shoe as much a sum of its parts as the talents that went into creating it.
