PHASE is constructed using the latest lamination techniques, with a minimal single-layer mesh upper and laminated reflective details. With an asymmetric lacing system and unique IBR outsole, PHASE provides maximum performance with minimum weight and interference. Zero-drop, 11mm stack height.
PHASE is built on our revolutionary IBR (Injection Blown Rubber) platform. R02 pushes the boundaries of material technology. IBR offers better abrasion resistance, grip and compression-set than injected EVA with lower density and weight than rubber. This provides a runner with incredible ground feel and running comfort in an amazingly durable, flexible and lightweight complete package.
