Saucony ISO Series

Saucony ISO Series

Saucony's premium cushion footwear, including the Triumph, the Hurricane, and the Zealot*, all feature the new ISOFIT System, designed to give runners a more comfortable, flexible fit than ever before.

ISOFIT System

It’s common for running shoes that offer lots of cushioning to feature bulky uppers that can feel heavy and stiff. Saucony's design team’s approach to the ISO•SERIES uppers was different. By combining a plush inner fit sleeve with a flexible external cage, ISOFIT technology provides a system that dynamically adapts to each individual part of the foot. In other words, it moves with the runner’s foot in motion. There is none of the bulkiness and stiffness traditionally associated with models in this class. The shoes are amazingly lightweight and flexible, especially when you consider how much impact protection they provide. 

*The Saucony Zealot is not currently in stock at Fleet Feet Knoxville. Please call us at (865)675-3338 to check for availability.
