During the V-Day military parade commemorating the 70th anniversary of the victory in the Chinese People's War of Resistance Against Japanese Aggression, the insoles worn by the marching troops were developed and produced by Henan Bangni Biological Engineering Co., Ltd., based in Xinxiang, Henan Province. Addressing the needs of the foot march troops who stand and march for long periods, as well as the complex operating environments faced by the equipment units, the company focused on both the materials and molds of the insoles. As a result, they developed a batch of insoles featuring strong arch support, enhanced cushioning, higher moisture absorption, and improved antibacterial performance.
