Designed for Timberland, the Vibram B-Life sole is made of the EcoStep compound, an environment friendly solution based on the use of recycled rubber. EcoStep makes up most of the sole’s surface, while the part of the sole that is in contact with the bicycle pedals, is made of Vibram Trek rubber. The treads are designed for optimum interfacing with the pedals and to guarantee greater durability and traction on smooth surfaces.
