According to the searched information, a double-layer composite flexible upper has the following characteristics: the upper is composed of a knitted surface layer and a TPU (thermoplastic polyurethane) yarn layer. The TPU yarn layer is attached to the surface of the knitted surface layer, covering the entire upper and providing additional support and protection. The upper structure TPU yarn layer may contain shock-absorbing protrusions and reinforcement stripes to enhance the wear resistance and support of the upper. The rear of the upper may be equipped with a strap and an anti-collision layer to provide additional safety and security. The design of the air perforations allows the upper to maintain ventilation and improves wearing comfort.
