At the same time, it has the advantages of rich colors and various patterns, and the price is cheaper than leather fabric, so it is popular with consumers. The super shock absorption function can protect the human body from strain during exercise, reduce the exercise pressure, and achieve the effect of relieving fatigue. At the same time, this insole is also light, and will not add additional weight to the exercise. The PU insole is commonly used for sports shoes of large brands.
