ASICS' I.G.S. (Impact Guidance System) is a fundamental design philosophy around which ASICS’ technical footwear is built. The aim of I.G.S is to encourage the foot to perform in a more natural manner. This is achieved primarily by encouraging the shoe to work with the foot rather than trying to control it.
The I.G.S philosophy was conceived in 2001 when ASICS footwear developers began to completely rethink the conventional wisdom commonly accepted in athletic footwear design. The main focus of I.G.S is the principle of ‘dynamic stability’. This involves incorporating systems into a shoe that will address all the forces applied to the foot and lower limb throughout the movements of a particular sport.
The most important thing to remember about I.G.S is that it is not just one feature working in isolation, but a series of interdependent and linked components. Any shoe wearing the I.G.S Badge of Approval comprises a series of inter-linked technical features that work together with the foot to produce more natural and therefore healthier foot motion.
If a shoe has an I.G.S badge, it means this particular model has been designed to operate at the absolute highest standard, given the biomechanical requirements of the particular sport it was designed for.
The I.G.S philosophy was originally inspired for the Running Shoe Category, but has now grown to cover a vast array of sports. To encourage natural motion, ASICS Footwear developers painstakingly scrutinise the individual needs of the shoe for biomechanical efficiency in that particular sport whether it be Running, Walking, Netball, Tennis, Football etc.
The result of all this research, scrutiny and development is arguably the most sophisticated performance shoe system ever produced - ASICS Impact Guidance System. (I.G.S)
