Coming February 2015 Saucony will release the Zealot running shoe. The Zealot is basically a replacement for the current Cortana with a 4mm offset and outstanding cushioning. It also features Saucony’s new Isofit system in which the laces attach to a cage external to the upper and adapts to the foot’s shape and movement using a stretchable mesh. In the midsole, the Zealot utilizes Saucony’s new PWRGRID+, which Saucony claims is a 20% increase in cushioning and a 15% increase in resiliency over the POWERGRID found in the Cortana 4 and many other Saucony shoes.
If you are currenty running on the Saucony Kinvara and feel you need a bit more support on your longer runs, then you should definitely consider the Zealot.
