The Saucony Hurricane ISO (also known as Hurricane 17) is the second model (after the Triumph ISO and just before the Zealot ISO, which will continue the Cortana 4) from ISO series to reach the market: premium running shoes with much more cushioning, sockless fit and the stabilizing support the Hurricane is well known for.
Most important update from its predecessor the Hurricane 16 is a complete new upper. Saucony's ISOFIT™ is basically composed of two elements: a plush inner fit sleeve and a flexible external cage. The floating support cage sits like a saddle over the fit sleeve, cradling the midfoot and moving with the runner’s foot in motion. A more solid heel counter helps providing a better stability.
Another major change takes place in the PWRGRID+™ midsole which has been increased by adding 3mm of foam to both the heel and forefoot providing 20% more cushioning without touching 8 mm offset delivering outstanding comfort and more impact protection.
Outsole has been redesigned adding an extra vertical flex groove to increase flexibility for smooth transition and features iBR+™ in more frequent impact zones to assure better response and durability.
