Unlike any other running shoe on the market. A breakthrough in running shoe design,Bikila® is our first model designed specifically to promote a more natural, healthier and more efficient forefoot strike. While many folks have been running in their Vibram FiveFingers® for years, the Bikila® is our first model created exclusively for a more natural running experience. Built on an entirely new platform, the Bikila® features a Dri-Lex® covered 3mm polyurethane insole (thickest under the ball of the foot) and a 4mm anatomical pod outsole design that offers more plating for underfoot protection. It also distributes forefoot impact without compromising important ground feedback essential to a proper forefoot-strike running form. To finish off this breakthrough design, the upper has a more athletic padded collar and topline, a single hook-and-loop closure, 3M™ reflective surfaces and tear-resistant TPU toe protection.
