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!
