Sir Isaac

Neutral Guidance Trainer

The Sir Isaac Neutral Guidance Trainer is designed for all runner types for everyday base-building and slower-paced running. Like all Newton shoes, the Sir Isaac offers highly responsive cushioning and ground feel, with a more level-to-the-ground platform and lighter weight. As our most traditional, structured and supportive running shoe, the Sir Isaac helps you transition into the Newton running experience.
