Ultra-light material provides lightness, quick start, and full energy feedback and rebound feeling. The fiber material is both lightweight and can effectively transfer the force between the front and rear palms, strongly improve the torsion resistance of the arch of the foot, and increase the rigidity and stability of the entire shoe body. The shoe body uses Peak's new seamless technology to connect the shoelace system and the heel. Different materials are superimposed on the heel to enhance the locking of the ankle. The shoelace system is located on the inside to enhance the sense of wrapping. It is lightweight and beautiful while strengthening the integrity of the shoe and foot.
