The midsole is made of U4ic composite material, which has a similar wearing feel and performance as AP+. It is lighter than EVA at the same volume, providing a more comfortable running experience. The midsole is equipped with INFINITY WAVE, which further improves performance. The two parallel WAVE layers are connected through high-elastic shock-absorbing connecting columns to more effectively absorb and disperse the impact on the foot, providing good cushioning and stability. The X10 wear-resistant rubber outsole is rich in rubber material and can effectively enhance the friction when the heel hits the ground.
