What are the names of Li Ning's running shoes?

Ultra-light 1 generation RUNFREE sole adopts ultra-light PHYLON and ultra-light rubber technology, which is light in weight.

On the basis of ultra-light generation 1, the ultra-light second-generation hummingbird enhances the support of the midsole and improves the comfort.

Ultra-light 3rd generation Tianyu has increased the support of arch and optimized the use of sole rubber on the basis of ultra-light 2nd generation. The decorative design of Phyllostachys pubescens can reduce the amount of rubber, reduce the weight of shoes, ultra-light PHYLON midsole and minimize the weight of products. The leaf stem TPU supports the arch of the foot, and the key parts of force transmission are made of anti-torsion and anti-slip rubber to ensure sports safety. Ultra-light rubber outsole, 20% lighter than ordinary rubber, minimizes the weight of the product.

The design concept of ultra-light 4th generation comes from China's Swallow Kite. The leather material of the vamp and the eager supporting structure of TPU refer to the skeleton structure of Swallow Kite, showing strong China characteristics. The sole is 22.7% lighter than the ultra-light third-generation sole, and the whole shoe is about 14% lighter. The sole adopts injection molding technology, and the material is more wear-resistant than the ultra-light third-generation sole. Rubber is used in key parts, which reduces the weight of the shoe body and is non-slip and wear-resistant.

The ultra-light fifth-generation Yu Xiang ultra-light fifth-generation running shoes based on swallows came into being. The light wings composed of progressive colors and 3M reflective support rods highlight lightness, the dovetail lines and silver decorative strips highlight speed, and the interlayer on the shoe body provides the guarantee of ventilation and comfort as always.

The hollowed-out design of the sole intuitively conveys the light information, the feather-like rubber distribution makes the contact between the sole and the ground feel smoother and softer, and the TPU support piece at the waist increases the strength of the bottom. Make the ultra-light fifth-generation products more stable and comfortable than the previous styles of this series. It can also provide anti-torsion protection during running. For the first time, the midsole is made of PHYLON material with high compression resistance, which has better toughness and elasticity. With thick insoles, sports performance has been greatly improved.
