    The Saucony Zealot is an all-around very solid shoe. The technologies that reside in this shoe, including the ISOFIT system and PWRGRID+ are really very sound advancements.

  • 86 / 100 | Road Trail Run

    I expect long term outsole wear to be outstanding. The ISOFIT upper is a comfort and fitting innovation.

  • 78 / 100 | Runblogger

    I have to start this review off by saying that the Zealot is a fantastic looking shoe, and the Viziglo orange colorway that Saucony sent me is bright. Very bright!

  • 78 / 100 | Running Competitor

    It wasn’t quite agile enough for faster turnover sessions on the track.
