The Bikila Shoe by FiveFingers is designed to create a more natural and efficient forefoot strike while providing plenty of ground feedback. These are the perfect shoes for runners seeking an almost-barefoot experience with durable FiveFingers protection. A 3mm polyurethane insole combined with a 4mm anatomical rubber outsole allows flexibility while distributing forefoot impact. The shoes have a single hook and loop closure as well as tear-resistant toe protection. They also have 3M reflective surfaces to help keep you safe.
