The three drops on toe, heel and bottom produce the whole shoe and represent the singularity of CCILU. The structure is strengthened by rib-like energy bars on the side wall. A Nylon shank on the arch stabilizes wearer’s foot. The rubber outsole provides a slip-resistant feature and the drop in the middle is diffused by covering the entire outsole and its' different color enhances the visual effect. With tech upper design, Diffusion boot is stylish and functional.
