Built on an entirely new platform, the Bikila features a Dri-Lex® covered 3mm polyurethane insole (thickest under the ball) and a 4mm anatomical pod outsole design that offers more plating protection, and distributes forefoot impact without compromising important ground feedback essential to a proper forefoot strike running form. A more athletic padded collar and topline, a single hook and loop closure, 3M reflective surfaces, and tear resistant TPU toe protection finish off this breakthrough design.
