The biggest selling point of these shoes is the silk upper, which is so thin and really excellent! The traditional saro weaving method is adopted, which enhances the strength and toughness of the upper and ensures breathability. 䨻 Silk is a nylon material with the characteristics of lightweight, high strength, and high toughness, which is 24% lighter than traditional mono yarn. In order to increase the strength of the shoe upper, in addition to strengthening the toe position, there are also support treatments on both sides of the shoe, and the faintly visible blue color is the support strip. The midsole is owned by Li Ning, and compared to the TPE material used in the non filament version of the Feidian Discovery, it has been replaced with aliphatic TPU material, which is lighter and more resilient. In terms of the outsole, the use of full palm tuff rb material is not a problem with wear resistance, but online evaluation shows average anti slip performance, and caution should be exercised on roads that have rained.
