Good to know

  • The Saucony Switchback ISO is a trail running shoe that is strategically intended for those who have neutral foot mechanisms.
  • With the utilization of the ISOFIT dynamic upper, the mesh quickly adapts to the shape, size, and movements of the foot. As a result, a sock-like fit is experienced by the runner.
  • Along with the ISOFIT technology is the integration of a BOA lacing system. This is essential in the easy and natural hugging and wrapping of the foot without sacrificing its comfortable and soft feel.
  • Integrated into the midsole of the shoe is the full-length, low profile EVERUN. This component of the Saucony Switchback ISO provides durable underfoot cushioning, flexibility and enhanced energy return.
