Sir Isaac Wide

Neutral Guidance Trainer

The Sir Isaac (Wide) Neutral Guidance Trainer accommodates a EE width and 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.

Through the end of June, Newton Running will donate $5 to Red Cross Colorado for every shoe purchased to benefit Black Forest fire victims.
