On a summer's day after the end of last season, the Arsenal defender visited the ASICS Institute of Sport Science located in Kobe, Japan, to find out more about his footwear.
In the institute, research and development has been carried out based on 'human-centric science', with the company's vision to 'create quality lifestyle through intelligent sport technology' leading the way.
Research on human characteristics, including the deformation and load of the body during exercise, has helped figure out the necessary functions for ASICS' products, while there has also been development of materials such as resins, rubber and sponge used in shoe soles and other parts.
On top of this, the institute places emphasis on quality control, including product durability. Everything is concentrated here.
