The first Nike Shox OZ shoes prototype is inspired by an exceptionally springy indoor running track at Harvard. The prototype looked more like a medieval torture device called The Boot and performed much the same way. This first Nike Shox OZ shoes prototype was used to find the optimal spring rate, but it’s clumsy and heavy metal frame did nothing to improve performance.
Based on the information extracted from its predecessor, the section prototype of the Nike Shox OZ shoes line was a scaled down, more stable shoe using a leaf shaped spring to provide the optimal spring of the first unit. Easier on the eyes with good cushioning, it lacked stability and durability.
The third attempt at Nike Shox OZ shoes produced a simpler, and more attractive cushioning system utilizing a closed leaf shaped spring, but still disappointed in durability, comfort, and stability.
The next generation of Nike Shox OZ shoes prototype attempted to solve the problem of durability and stability by replacing the closed leaf spring with a hinged carbon fiber shell, creating a something that looked like a running shoe on a diving board. This breed of spring failed completely to provide enough resistance on impact.
