Every KD shoe is famous for balancing the comfort and feedback of shoes. In order to achieve this goal, KD 12 changed the structure of traditional shoes, and turned the often neglected elements into the key points to improve performance. And this element is: midsole. Leo Chang, senior creative director of Nike basketball shoes, said: "The midsole is the unsung hero in the structure of sports shoes. In the past few decades, the application of midsole has hardly changed, but it is its existence that separates the foot from the cushion. "

Nike announced kevin durant's 12 signature shoe: KD 12, but the midsole provided limited upper structure and support. Because there is no other function, the existence of the midsole blocks the contact between athletes and the cushioning air cushion of sports shoes. However, Zhang Chuanxi and Nike engineers improved the position of the air cushion in sports shoes by further connecting the full palm Air Zoom air cushion with the upper. Qi Li, an expert from the fields of manufacturing, design and testing, cooperated to find a better solution. For example, the shoe factory, which is responsible for sewing the midsole with precise technology, helps to determine where the air cushion needs elasticity. The groove pattern design similar to the air cushion in KYRIE 5 is also applied to the Air Zoom air cushion in KD 12, so that it can bend according to the wearer's movement direction.

What is a midsole? The midsole is a thin layer of textile, usually sandwiched under the insole and above the midsole. It provides the structure, support and shaping of the upper. Zhang Chuanxi said, "Because the size of the midsole determines the size of shoes, more than half of KD 12 has corresponding air cushions, ranging from US7 for boys to US 18 for kevin durant. This is also Nike's further efforts to adjust the size range of air cushions. Let everyone who wears KD 12 have a more suitable configuration. "

Zhang Chuanxi's manuscript KD 1 2 KD12' Children of the 1990s' will be first sold in Nike and Nike designated retail stores on April1day. The black-and-white color matching KD KD 12 "Day One" will be sold in Nike designated stores on April 7th.
