Shox R4 is technology developed by Nike and incorporated into several of their flagship athletic shoes. Shox are small hollow columns that make up the midsole of the shoe. They are mostly made of rubber. There are many different formations that Shox R4 come in, but they usually come with four circular columns in a square formation for maximum cushioning. There can also be five or six Shox that vary in height, and triangular and rectangular Shox that provide better stability. Some shoes have midsoles made entirely of Shox.

1984
The first Shox 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 Shox prototype was used to find the optimal spring rate, but it’s clumsy and heavy metal frame did nothing to improve performance.

1984-1986
Based on the information extracted from its predecessor, the section prototype of the Nike Shox 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.

1986
The third attempt at Shox produced a simpler, more attractive cushioning system utilizing a closed leaf shaped spring, but still disappointed in durability, comfort, and stability.

1987
The next generation of Shox prototype attempted to solve the problem of durability and stability by replacing the closed leaf spring with a hinged carbon fiber shell, creating something that looked like a running shoe on a diving board. This breed of spring failed completely to provide enough resistance on impact.

1990
A few years later, and still a decade from launching the Shox shoe line, Nike tests the first shoes that are a recognizable ancestor of the modern Shox. By integrating the stability of the spring plate from the previous designs with injection-molded support columns, Nike finally made progress in the creation of Shox technology.

1997-1998
New, high tech, high durability materials make the leaf spring obsolete and bring about the current form for Nike Shox: four cushioning columns between two resilient plates. The results is an effective cushioning system with a high energy return.

2001
Nike releases the first Shox based shoe.

2004
The release of two popular Shox basketball shoes, the Nike Shox Explosive and the Nike Shox Elevate. The Shox VC IV, Shox signature shoe for Vince Carter, is also released
