EVERUN and ISOFIT are things of the past as the new era of Saucony shoes is here, now featuring PWRRUN and FORMFIT on the Hurricane 22! PWRRUN is the next evolutionary step of EVERUN giving you an even more plush cushioning without losing responsiveness, and did we mention it's 25% lighter than its predecessor? FORMFIT is a luxurious 360-degree wrap around the foot to feel locked in without pressure points or too much tinkering. Still supported like previous iterations for a medial posting, the Hurricane is back and better than ever and ready for you to take it for a spin!
